I haven't been able to get production quality, but then I'm no artist. ;-) Yesterday I commited ports of: mpeg_encode -- UCB's mpeg-I encoder mpegedit -- A buggy editor for mpeg video streams mplex -- an mpeg audio/video => system multiplexor splitmpg -- a system de-multiplexor and I've got ports on the way of mpeg_bits and mpeg_blocks They work with mpeg_encode to tune a parameter file. It wouldn't be too tough to edit nearly any mpeg stream as follows: 1) get the file, say http://www.heuris.com/clips/martini.mpg 2) use splitmpg to de-multiplex the audio/video 3) use musicout to dump the audio to pcm; sox to convert to somthing usable; I haven't found anything to dump video frames, yet. 4) use mpeg_edit, auedit, whatever to muck with these. 5) reconvert the audio to mpeg; re-roll (with mpeg_encode) the video if you somehow unrolled it 6) multiplex the streams back together with mplex (or system_encode) 7) play it on your favorite player. eric. -- erich@lodgenet.com http://rrnet.com/~erich erich@rrnet.com
