NAME

ustreamer-dump - Dump uStreamer's memory sink to file

SYNOPSIS

ustreamer-dump [OPTIONS]

µStreamer-dump (ustreamer-dump) writes a local stream from ustreamer to a file or redirect it to other utilities (such as ffmpeg).

ustreamer requires at least the --sink option to operate.

To output ustreamers sink "test" to ffmpeg, and into a file called test.mp4:

ustreamer-dump \

--sink=test \ # Use ustreamer sink "test"

--output - \ # Output to stdout
| ffmpeg -use_wallclock_as_timestamps 1 -i pipe: -c:v libx264 test.mp4

-s, --sink name: Memory sink ID. No default.
-t, --sink-timeout sec: Timeout for the upcoming frame. Default: 1.
-o, --output filename: Filename to dump output to. Use '-' for stdout. Default: just consume the sink.
-j, --output-json: Format output as JSON. Required option --output. Default: disabled.
-c, --count N: Limit the number of frames. Default: 0 (infinite).
-i, --interval sec: Delay between reading frames (float). Default: 0.

--log-level N: Verbosity level of messages from 0 (info) to 3 (debug). Enabling debugging messages can slow down the program. Available levels: 0 (info), 1 (performance), 2 (verbose), 3 (debug). Default: 0.
--perf: Enable performance messages (same as --log-level=1). Default: disabled.
--verbose: Enable verbose messages and lower (same as --log-level=2). Default: disabled.
--debug: Enable debug messages and lower (same as --log-level=3). Default: disabled.
--force-log-colors: Force color logging. Default: colored if stderr is a TTY.
--no-log-colors: Disable color logging. Default: ditto.
