<B>WARNING:B> This does not work on any old SWF! It has to be a
video/audio-dominated SWF. Dont be surprised if it fails to extract
content from some arbitrary SWF you built or download. In particular,
it does not handle vector animation.
Supports Flash MX and Flash 8 video (that is, Sorenson H.263 and On2
VP6.2 respectively). Flash screen video and VP6 with alpha are both
untested but might work.
Supports MP3 audio. Other audio formats are untested but might work.
Does not support multiple video or audio streams in the same file.
Emits Greenwich time in the creationdate meta tag, not local time.
