Hi, This made me test Gem on my machine as well and it turns out that:
mjpeg: Does not play, throwing lines of the following onto the console: [mjpegb @ 0xb7405b48]not mjpeg-b (bad fourcc) mpeg4: Takes 99% cpu on a 1.6GHz CoreDuo from Intel This is with pd 0.40-2 and a recent cvs Gem checkout. Any pointers appreciated, gem and video codecs nightmare otherwise. regards, Peter patrick wrote: > hi, > > i am on linux running the very last version of gem from cvs. i am trying > to find a good codec for gem. here's my basic research: > > --------------------------------------- > the best codec for quicktime is jpeg: > transcode -i yourvideo -y mov,null -F jpeg,,jpeg_quality=70 -o gem.mov > > gem cpu usage is 38% > mplayer cpu usage is 27% > ffplay cpu usage is 16% > lqtplay cpu usage is 1% ** > > --------------------------------------- > for avi i tried ffmpeg / mjpeg: > transcode -i yourvideo -y ffmpeg,null -F mjpeg -o gem.avi > > gem cpu usage is 33% > mplayer cpu usage is 33% > ffplay cpu usage is 22% > > --------------------------------------- > the really best codec around is mpeg4: > transcode -i yourvideo -y ffmpeg,null -F mpeg4 -o gem.avi > > gem cpu usage is: crashed** > mplayer cpu usage is 16% > ffplay cpu usage is 11% > > > * lqtplay seems to make a excellent job for decoding is own codec. would > it be possible to make a pix_qt based on the source of this player??? > > ** anybody can test this codec? that would be my second choice... after > lqtplay ported to gem... > > pat > > > _______________________________________________ > [email protected] mailing list > UNSUBSCRIBE and account-management -> > http://lists.puredata.info/listinfo/pd-list _______________________________________________ [email protected] mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
