|Specifies the path name to the raw CD device. If this option is not used, the default device to be used is the first drive set up with the xmcd configuration program (See below).|
|-help||Causes command line usage information to be displayed on stderr.|
Causes verbose debugging diagnostics to be displayed on stderr.
The level specifies the type of debugging messages desired:
1 General debugging 2 Device I/O debugging 4 CD information debugging 8 User interface debugging 16 Remote control debugging 32 Sound DSP and output file/pipe debugging 64 Message of the day debugging
You may add the values together to enable multiple debugging types (i.e., A value of 3 turns on both General and Device I/O debugging).
|Causes xmcd to install its own colormap. This may be desirable if xmcd is to be used at the same time as other color-intensive applications, which would otherwise cause xmcd to be unable to allocate all its needed colors. Note that when running on an X display that does not support many concurrent colormaps, this may cause other windows to change colors when xmcd has the input focus.|
Causes a command to be sent to another running
The command and appropriate arguments are specified at the
invoking shell (or shell script) as command-line arguments,
After the command is delivered, the "sender"
xmcd process exits,
and the "receiver" process responds by executing the command.
In effect, the sender becomes a remote control for a running
xmcd session. See "COMMANDS" below for a list of supported
The sender xmcd process can be invoked on the same host or on a different host than the receiver xmcd process. By default, the sender will attempt to locate an xmcd process running on the same X display (determined by the DISPLAY environment variable or the -display option), and controlling the same default CD device. You may specify the device via the -dev option to override the default. Use of the -dev and -rmthost options on the senders command line can resolve ambiguities when there are multiple xmcd clients displaying on the same X server.
|This may be used with the -remote option to specify the host on which the receiver xmcd client must be running.|
|-c device (Solaris only)|
|Same as the -dev option.|
|-X (Solaris only)|
|Causes the exitOnEject parameter to be set to True.|
|-o (Solaris only)|
|This option has no effect.|
Xmcd has many adjustable X resources to customize its look and feel, as well as its behavior. Notably, the colors of virtually every feature on xmcds windows can be changed, as well as the text fonts. All text labels can also be changed (for example, to another language).
There are too many resources to list here, but the resource names and their defaults (plus descriptive comments) can be found in the XMCDLIB/app-defaults/XMcd file (where XMCDLIB is the xmcd library directory specified during installation, typically /usr/lib/X11/xmcd). It is not recommended that you change values in the XMCDLIB/app-defaults/XMcd file, unless you want the changes to be forced upon all users of xmcd on the system. Instead, make a copy of this file, change the copy as you see fit, then place it in your $HOME/.xmcdcfg directory. Your custom resource settings will then override the defaults when xmcd is subsequently started.
You may specify a command as an xmcd command line argument, to make xmcd execute the command after initial startup. For example, the following command starts xmcd and then begins playing at track 4:
xmcd play 4 &
If the -remote option is used, then the command is sent to another running xmcd process for execution (See "OPTIONS" above).
The supported commands are:
Some of these commands, when used in start-up mode, do not perform a meaningful function. For example, the "track prev" command is not useful just after xmcd startup. It is more appropriate to use this command in the remote control mode.
stop Stop playback. play [track# | min:sec | track#:min:sec] Start playback. You may also specify the starting track number, and/or the starting minute and second offset. pause Pause the playback. You may resume the playback by using either the pause command again, or the play command. sample Start sample playback. This will play the first 10 seconds of each track. disc lt;load | eject | prev | next | disc#> Perform a disc operation: Load or eject the CD, or change to another disc on a multi-disc changer. track <prev | next | track#> Perform a track operation: Change to the previous or next track, or a specified track number. index <prev | next> Perform an index operation: Change to the previous or next index. lock <on | off> Enable or disable the caddy (or disc tray) lock. When enabled, pressing the eject button on the drive will not eject the CD. You can only change the lock state when a CD is loaded and is not playing. shuffle <on | off> Enable or disable shuffle (random play) mode. Shuffle can be enabled in this manner only when playback is not in progress. When shuffle is enabled, any program sequence is cleared and segment play is canceled. repeat <on | off> Enable or disable repeat mode. program <clear | save | track# ...> Clear, save or set a track program sequence. Track numbers may be space or comma-separated. When a program is set in this manner, shuffle mode will be disengaged and segment play will be canceled. volume <value# | linear | square | invsqr> Volume control operation. You can specify a numeric value to set the volume level (The range is 0 to 100), or change the volume controls taper characteristic: linear, square, or inverse-square. This control operates the hardware volume control on the CD drive in Standard playback mode, or the computers audio hardware in CDDA playback mode. It has no effect on the data of the CDDA save to file or CDDA pipe to program outputs. balance value# Balance control. The value should be between 0 and 100. 50 is center, 0 is full-left, and 100 is full-right. This control operates the hardware volume control on the CD drive in Standard playback mode, or the computers audio hardware in CDDA playback mode. It has no effect on the data of the CDDA save to file or CDDA pipe to program outputs. route <stereo | reverse | mono-l | mono-r | mono | value#> Channel routing control. Use one of the appropriate keywords, or a value as follows:
0 Normal stereo 1 Reverse stereo 2 Mono-L 3 Mono-R 4 Mono-L+R
outport <speaker | headphone | line-out | value#> CDDA playback output port selection. The speaker, headphone and line-out keywords are toggles. Alternatively, you may specify a numeric value, as follows:
1 Speaker 2 Headphone 4 Line-out
You may add the values together to enable multiple output ports (i.e., A value of 3 turns on both Speaker and Headphones). When the value is set to 0, the port setting is unmodified. Note that this command may be meaningful only on some platforms, and only certain ports may be available on a particular architecture. See the PLATFORM file for details.
cdda-att <value#> CDDA attenuator level. The valid range is 0 to 100. Note that in contrast to the volume command, this setting does not operate any hardware. It works by scaling the CDDA audio samples, and thus has no effect in Standard playback mode, but affects all CDDA modes (CDDA playback, CDDA save to file and CDDA pipe to program). time <elapse | e-seg | e-disc | r-trac | r-seg | r-disc> Change the time display mode. Select from elapsed track time, elapsed segment time, elapsed disc time, remaining track time, remaining segment time or remaining disc time. on-load <none | spindown | autoplay | autolock | noautolock> Enable or disable options when a CD is loaded. The spindown option will cause the CD to stop after loading to conserve the laser and motor. The autoplay option will cause the CD to automatically start playing after loading. The autolock option causes the caddy or disc tray to be automatically locked. The none, spindown and autoplay options are mutually-exclusive. on-exit <none | autostop | autoeject> Enable or disable options when xmcd exits. The autostop option will cause xmcd to stop playback, and the autoeject option will cause xmcd to eject the CD. Use none to cancel these options. on-done <autoeject | noautoeject | autoexit | noautoexit> Enable or disable options when xmcd is done with playback. The autoeject option causes xmcd to eject the CD. The autoexit option will cause xmcd to exit. on-eject <autoexit | noautoexit> Enable or disable options when xmcd ejects a CD. The autoexit option will cause xmcd to exit after ejecting the CD. changer <multiplay | nomultiplay | reverse | noreverse> Enable or disable multi-disc changer options. The multiplay option specifies that xmcd plays all discs in sequence. The nomultiplay option will cause xmcd to stop after the current disc is done. The reverse option implies multiplay, except that the disc order is reversed. mode <standard | cdda-play | cdda-save | cdda-pipe> Selects the playback mode. See "PLAYBACK MODES" below for details about the modes. jittercorr <on | off> Enable or disable CDDA jitter correction. trackfile <on | off> For CDDA save to file mode, specifies whether a separate file should be created for each CD track. subst <on | off> For CDDA save to file mode, specifies whether space and tab characters in the output file path name should be substituted with underscores (_). This makes the files easier to manipulate while using the UNIX command shell. filefmt <format> Specifies the output audio file format if running in CDDA save to file or CDDA pipe to program modes. The format is one of the following: raw, au, wav, aiff, aiff-c, mp3, ogg, flac, aac or mp4. outfile <template> Specifies the output audio file path name template if running in CDDA save to file mode. See the help file for the CDDA output file path template text box for a description on the special tokens that could be used in the template. pipeprog <path [arg ...]> Specifies the external program to which the audio stream will be piped to when running in CDDA pipe to program mode. compress <<0 | 3> [bitrate#] | <1 | 2> [qual#]> Selects the compression mode for compressed file formats, as follows:
For MP3, the modes are as follows:0 Constant bitrate (CBR) 1 Variable bitrate (VBR, old algorithm) 2 Variable bitrate (VBR, new algorithm, faster) 3 Average bit rate (ABR)
For Ogg Vorbis and MP4, all modes are VBR, as follows:0, 3 Use an average bit rate 1, 2 Use a quality factor
For FLAC, the modes are as follows:0 None 1 Enable exhaustive LP coefficient quant. search 2 Enable encoding correctness verification 3 Enable both
For AAC, all modes are VBR, as follows:0 Use an average bit rate, MPEG-2 1 Use a quality factor, MPEG-2 2 Use a quality factor, MPEG-4 3 Use an average bit rate, MPEG-4
For modes 0 and 3, an optional bitrate (in kb/s) sub-argument can be specified. The supported bitrates are a discrete set of numbers from 32 to 320. A value of 0 can also be used to indicate the use of an internal default. For modes 1 and 2, an optional quality factor (from 1 to 10) sub-argument can be used. Lower bitrates and quality factor values yield smaller files whereas higher numbers produce higher audio quality. For AAC and MP4 formats, the bitrate you specify will be double the actual bitrate (e.g., if you specify 128kbps, the actual bitrate used will be 64kbps). The bitrate or quality values, if specified, are ignored for the FLAC format.
min-brate <bitrate#> In average bitrate and variable bitrate modes, this commands lets you specify a low bitrate limit. The encoder will not drop below this limit while dynamically changing the bitrate. A value of 0 can be specified to indicate the use of an internal default. This parameter has no effect on the FLAC, AAC or MP4 format. max-brate <bitrate#> In average bitrate and variable bitrate modes, this commands lets you specify a high bitrate limit. The encoder will not go above this limit while dynamically changing the bitrate. A value of 0 can be specified to indicate the use of an internal default. This parameter has no effect on the FLAC, AAC or MP4 format. coding <stereo | j-stereo | force-ms | mono | algo#> This command selects the stereo mode and encoding noise-shaping/psychoacoustics algorithm.
For MP3, the algorithm is a number from 1 to 10. Lower numbers gives faster encoding whereas higher numbers produce higher audio quality.
For AAC and MP4, stereo disables the mid/side coding, j-stereo and force-ms are synonymous, and mono is not supported. An algorithm value of 10 enables temporal noise shaping (TNS).
For FLAC, the stereo modes have no effect, but the algorithm value selects between faster encoding versus slightly better compression.
For Ogg Vorbis, this parameter has no effect.
lowpass <off | auto | freq# [width#]> This allows a lowpass filter to be added. The off setting means no filter, the auto setting causes the encoder to determine whether a filter should be added and its parameters. Specifying a frequency (and optionally, a width) will enable the filter in manual mode. The frequency and width are both in Hz. The valid frequency range is from 16 to 50000 Hz. For MP3, the filter functions fully as described. For AAC and MP4, the freq can be used to limit the bandwidth, but the width value is ignored. For Ogg Vorbis and FLAC, these parameters have no effect. highpass <off | auto | freq# [width#]> For encoding to MP3 files, this allows a highpass filter to be added. The off setting means no filter, the auto setting causes the encoder to determine whether a filter should be added and its parameters. Specifying a frequency (and optionally, a width) will enable the filter in manual mode. The frequency and width are both in Hz. The valid frequency range is from 500 to 50000 Hz. The lower limit is imposed by the polyphase filter implementation in the MP3 encoder. For non-MP3 formats, these parameters have no effect. flags <[C|c][O|o][P|p][E|e][I|i]> This allows you to specify some MP3 header and frame flags. The letter c denotes the "copyright" flag, the letter o denotes the "original" flag, the letter n denotes the "no res" (disable bit reservoir) flag, the letter e denotes the addition of a 2-byte checksum to each frame for error correction, and the letter i indicates strict ISO compatibility. The use of a upper-case letter turns on the flag, and lower-case turns off the flag. Multiple flags may be specified together. tag <off | v1 | v2 | both> This command specifies whether CD information (such as album and track artists and titles, genre type, etc.) should be added to the CDDA output file. For MP3, the information is added to either the version 1, version 2 or both versions of the ID3 tag areas. For Ogg Vorbis, FLAC and MP4, the information is added to the metadata area. to
Note: An ID3v2 tag will not be added to the CDDA pipe to program MP3 stream regardless of the setting of this command.
lameopts <<disable | insert | append | replace> [options]> This command allows you to query or set command line options to be passed directly to the LAME MP3 encoder, and control how those options will be passed. This facilitates the use of advanced or experimental LAME features that cannot otherwise be invoked via the xmcd graphical user interface for setting encoding parameters. The following keywords control how the command line options are to be passed:
disable: No additional command line options are to be passed.
insert: The specified options are to be inserted before the standard options.
append: The specified options are to be appended after the standard options.
replace: The specified options are to be used instead of the standard options.
Standard options refers to the command line options that xmcd generates, based on the current settings of the controls in the "Encoding Parameters" options window.
motd Retrieve and display messages from the xmcd MOTD server, if any. window <modechg | iconify | deiconify | raise | lower> Xmcd window control. The modechg command causes the main window to toggle between the normal mode and basic mode. In normal mode, all controls and indicators are available. In basic mode, xmcd shrinks to a smaller size and only basic controls are shown. The iconify, deiconify, raise and lower commands cause the xmcd window to change as specified. quit Causes xmcd to exit. debug <level#> Set the debug level. When debug level is non-zero, xmcd generates verbose debugging diagnostics to be displayed on stderr. See the description for the -debug option above for supported level values.
The X resources described in the previous section affect the general appearance and behavior of xmcd. There are two additional configuration files which are used to adapt xmcd to your site requirements. The first of these contain common parameters, and the second contain configurable parameters that must vary on a per-drive basis. For example, in some cases xmcd must operate the drive differently depending upon the brand and model of the drive. Thus, there must be a separate configuration file for these parameters per-device. The common parameters file is XMCDLIB/config/common.cfg and the device-specific parameters file is XMCDLIB/config/DEVICE (where XMCDLIB is typically /usr/lib/X11/xmcd and DEVICE is the base name of the raw device special file for the CD drive; e.g., /usr/lib/X11/xmcd/config/rcd0). A configuration program XMCDLIB/config/config.sh is provided to make maintaining these configuration file easy (Note: on SCO UNIX/Open Desktop/Open Server systems the configuration program can also be invoked as "mkdev xmcd").
You should always use the configuration program to set the configuration parameters when installing xmcd for the first time, or when the CD hardware configuration has changed. If this is not done then xmcd will probably not operate correctly with your CD drive.
WARNING: If xmcd is not correctly configured, you may cause xmcd to deliver commands that are not supported by your CD drive. Under some environments this may lead to system hang or crash.
You can override some of the device-specific configuration parameters by adding your own configuration files. Xmcd will also look in the $HOME/.xmcdcfg/common.cfg and $HOME/.xmcdcfg/DEVICE files for common and device-specific parameters (where $HOME is your home directory and DEVICE is as specified above). Parameters found in this file will override the system defaults (except those parameters that cannot be overridden; see the comments in the XMCDLIB/config/device.cfg for details).
The basic functions of xmcd are designed to operate the same way as on a real stereo CD player. The pictorial symbols used on the main window buttons are intended to illustrate the function in a non-language-specific manner. If enabled, a small "tooltip" will appear after a short delay, when you position the mouse cursor over any xmcd main window feature. The tooltip contains textual description of the feature.
The CD information and track programming functions are operated via the CD Information subwindow. You open the subwindow by clicking the CD Information button (file cabinet symbol) on the main window (See "CD DATABASE" below).
There is not a per-item description of all the features here, because full on-line help is available (See "ONLINE HELP" below).
For general information about xmcd, click the wwwWarp (world symbol) button on the xmcd main window and select Xmcd help... in the menu. You can also get specific help information about each button, control, indicator, text entry area, selection list by positioning the mouse cursor over the desired item, then clicking the third mouse button. A pop-up window will appear, containing the relevant help text.
You can program xmcd to play only certain tracks, in a custom sequence. To do so, invoke the CD Information window (by clicking the CD Information button on the main window). Select the desired track by clicking on the entry in the Track list, and click the Add button to add to the play sequence. Notice that the track number appears in the Program sequence text field. You can also type the track numbers, separated with commas or spaces, directly in the Program sequence field. Repeat until all desired tracks have been entered, then click the Play/Pause button (on the main window) to start the program play.
When a program sequence is defined, the prog indicator in the main window display area "illuminates". To erase the program sequence, click the Clear button on the CD Information window. You may also Save a program sequence, so that the next time you load the same CD the program will automatically be applied. The Clear button will also delete the saved program.
Unless explicitly disabled, xmcd will automatically query the Gracenote CDDB Music Recognition Service for information about the loaded CD. This information includes the artist/title, track titles, genre, and much more, and is displayed on the CD Information window and several of its sub-windows.
You may also add, modify or enhance the displayed information, in the rare circumstance that CDDB does not have data pertaining to your CD, or if the CDDB-supplied data is incomplete or in error. You can then submit the changes back to CDDB.
You should perform a "submit" operation (click the Submit button) after typing in the changed information before ejecting the CD or exiting, or the information will be lost.
The CD Information window should prove to be intuitive to use. You may use the on-line help system to obtain specific help information about the various buttons and items.
The CD information, once queried from CDDB, is stored in a local cache and managed by the CDDB library. This reduces unnecessary Internet connections to the CDDB servers.
This release of xmcd also supports reading the CD-TEXT data from the disc for CD information. Only some recent CDs are produced with CD-TEXT data and this data can only be read on CD drives with CD-TEXT capability.
For backward compatibility, this release of xmcd will also read the old-style local CD database files previously generated by xmcd versions 1.x and 2.x. No capability is retained in this release to write/update the old-style CD database files.
The priority of the CD information schemes (CDDB, CD-TEXT or local CD database files) is controlled via the cdinfoPath parameter in the common.cfg file.
For more information about Gracenote CDDB, read the CDDB file included with this release, and visit the http://www.cddb.com web site for details.
While xmcd is running, the file /tmp/.cdaudio/curr.nnnn (where nnnn is the hexadecimal representation of the CD drives device number) contains the device node path, the music genre, and disc identification information pertaining to the currently loaded CD. Other applications may read this file to identify the currently loaded disc.
This release supports the following user-selectable playback modes (via the Options pop-up window):
More than one of the three CDDA modes can be selected at the same time. For example, if both the CDDA playback and the CDDA save to file buttons are selected, the two functions will be performed simultaneously. Note that on most systems, only one program can access the systems DSP at a time, therefore you will likely not be able to select CDDA playback and CDDA pipe to program at the same time, where the external program is itself an audio player.
Standard playback When playing an audio CD, the audio output is the analog "line out" connection on the back of your CD drive. There should be an audio cable connecting this output to your computer audio hardware CD input (or to an externally amplfied speaker or stereo system). The audio output is also available at the CD drives front panel headphone connection, if so equipped. The volume control slider bar on xmcd affect the CD drives built-in volume control, if the drive has such controls. This is the mode that previous releases (xmcd version 1.x through 3.0) supported.
CDDA playback When playing a CD in this mode, xmcd extracts the CD digital audio data off the CD drive over the data cable (e.g., SCSI or ATAPI/IDE). Then, it sends the data to the DSP (digital signal processor) device in your computers audio hardware for real-time playback. The audio is typically heard through the computers built-in speakers. No signal is produced at the line-out or headphone connections of the CD drive. The xmcd volume control slider bar affects the computers DSP device.
CDDA save to file When playing a CD in this mode, xmcd extracts the CD digital audio data off the CD drive over the data cable (e.g., SCSI or ATAPI/IDE). Then, it writes the data into a file of your choosing. The xmcd volume control slider does not affect the data written to the output file. The output file format can be selected to be one of the following:
Format Ext Description ------ ----- --------------------------------------- RAW .raw Little-endian, 16 bit, 44.1 kHz, stereo AU .au Big-endian, 16 bit, 44.1 kHz, stereo WAV .wav Little-endian, 16 bit, 44.1 kHz, stereo AIFF .aiff Big-endian, 16 bit, 44.1 kHz, stereo AIFF-C .aifc Big-endian, 16 bit, 44.1 kHz, stereo MP3 .mp3 MPEG 1.0 Layer III compressed Ogg .ogg Ogg Vorbis compressed FLAC .flac Free Lossless Audio CODEC compressed AAC .aac AAC (MPEG-2 or MPEG-4) compressed MP4 .mp4 MP4 (MPEG-4) compressed
The file can be played later using an appropriate playback utility, or converted to another format. This mode will typically run faster than real-time with the non-compressed formats. With the compressed formats, it depends on the CPU performance of your system.
CDDA pipe to program When playing a CD in this mode, xmcd extracts the CD digital audio data off the CD drive over the data cable (e.g., SCSI or ATAPI/IDE). Then, it pipes the data stream to an external program that you specify. The output format is selected as in the CDDA save to file mode. This mode can be used with an external audio player, encoder, or other digital audio manipulation program. The external program must be capable of accepting audio data on its standard input, in one of the formats listed above.
NOTE: The CDDA (CD digital audio) modes will function only on CD drives that provides this capability, and only on some OS and hardware platforms. See the RELNOTES file for details about platform support and other CDDA related notes.
There is full localization support in xmcd if it is compiled with X11R5 or later header files and libraries.
The "classic" CDDB service supplies data in the ISO Latin-1 format only, multi-byte characters are not supported.
The CDDB2 service supplies data in UTF-8 data format, which is identical to US-ASCII for single-byte characters. Multi-byte UTF-8 characters are also supported when xmcd is linked with X11R5 or later. By default, xmcd will translate the characters to ISO Latin-1 (ISO 8859-1, for English and many European character sets). By changing the setting of the charsetConvMode parameter in the common.cfg file, you can have xmcd display the UTF-8 data without conversion (good for US-ASCII or if you are using UTF-8 fonts), or attempt to convert UTF-8 strings to the default character set as specified by the LANG environment variable. This conversion will occur only if the systems list of locales also support UTF-8. As distributed, xmcd is configured to display in a generic family of X fonts denotes similar to the following:
This will normally work correctly with English and any ISO Latin-1 European character set, as long as your X display server supports all the required fonts. To display in other languages, you must set your LANG environment accordingly, and change xmcd to use the appropriate fonts. That can be accomplished by modifying the various XMcd*classname.fontList parameters in the XMCDLIB/app-defaults/XMcd file (system wide) or your $HOME/.xmcdcfg/XMcd file (per-user). Be sure that the fonts you specify is actually supported by your X display server. See xlsfonts(1) and your X window system documentation about font configuration.
Moreover, all titles and descriptions in xmcd are configurable in the XMcd X resource file. US-English is distributed by default, but the file may be modified to use any other language as desired. See "X RESOURCES" above.
Not all platforms and CD drives support all the features of xmcd. For example, some drives do not support a software-driven volume control. On these drives the xmcd volume control slider may have no effect, or in some cases it is made to function as a mute control (i.e., it will snap to the full-off or full-on positions only). Similarly, the caddy lock, eject and index search buttons found on xmcd may not have any effect on drives that do not support the appropriate functionality.
The remote control feature (using the -remote option) is governed by the standard display server security mechanisms of the X window system. In order for an xmcd sender client to communicate with a running xmcd receiver client, the sender must have the appropriate access permissions to the receiver clients X display. See xhost(1), xauth(1) and Xsecurity(1) for more information. If logging is enabled, remote control activity is logged by the xmcd receiver client in the $HOME/.xmcdcfg/remote.log file for each xmcd user.
The lame(1) MP3 encoder program must be installed on your system in order for xmcd to perform CD ripping to MP3 format files. Similarly, the faac(1) encoder program must be installed on your system for the AAC and MP4 formats.
Your copy of the xmcd executable must be compiled and linked with the Ogg Vorbis and FLAC encoder libraries in order to perform CD ripping to these formats. See the INSTALL file for details.
The LANG environment variable sets the default character set. See "LOCALIZATION" above.
For the wwwWarp feature, xmcd invokes the Netscape, Mozilla, Galeon or Opera web browser to display the contents. Xmcd searches a number of "standard" locations for the web browser executable. If you have multiple browsers installed and would like to direct xmcd to use a particular executable, or if your browser executable is installed in a non-standard location, then you may set the BROWSER_PATH environment variable on the shell command line to the web browser executable you desire.
(For Bourne Shell and Korn Shell users): BROWSER_PATH=/usr/local/bin/mozilla; export BROWSER_PATH
(For C Shell users): setenv BROWSER_PATH /usr/local/bin/mozilla
you may put the above command in your $HOME/.profile (sh/ksh) or $HOME/.cshrc (csh) to set this automatically each time you log in.
The LAME_PATH environment variable may be used to specify the path to the lame(1) MP3 encoder program.
The FAAC_PATH environment variable may be used to specify the path to the faac(1) AAC and MP4 encoder program.
The AUDIODEV environment variable may be used to specify an alternate audio device when running xmcd in the CDDA playback mode. The default audio device is write method dependent as follows:
AIX write method: /dev/paud0/1 (PCI audio) AIX write method: /dev/baud0/1 (MCA audio) ALSA write method: plughw:0,0 HP-UX write method: /dev/audio Linux/OSS write method: /dev/dsp OSF1 write method: 0 Solaris write method: /dev/audio
In addition, with the OSS and ALSA write methods, the MIXERDEV environment variable may be used to specify the PCM mixer channel device. The default is /dev/mixer for OSS, and default for ALSA.
On FreeBSD with ATAPI CD drives, xmcd will automatically use either the CDIOCREADAUDIO ioctl or the pread(2) system call for CDDA reads, based on the running kernel version. You may override the default by setting the environment variable CDDA_USE_PREAD to 0 or 1, respectively. Normally this is not necessary.
