swf2flv - Transform a video SWF into an FLV
swf2flv [options] file.swf file.flv

With respect to video and audio content, FLV and SWF files have very similar data inside, and differ primarily in metadata. Very roughly, one can think of an FLV file as a subset of a SWF file.
Therefore, one can easily transcode from SWF to FLV and back without much work apart from fiddling with headers and the like.
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.
