hi IOhannes, thank you for your interest. here's the video (long life to gary burton).
http://www.workinprogress.ca/pd/gem/ i was wrong! lqtplay takes the same cpu as gem when not rendering (pix_texture). ffplay is the best player for the quicktime jpeg with only 16% of my cpu. why i would like to have ffmpeg / mpeg4 in gem is because of the size of the movie (3.5M for mpeg4 / 10M for quicktime and mjpeg). i would like to know what format / codec people use with pix_film under linux. patrick IOhannes m zmoelnig wrote: > 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% ** >> >> * 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??? >> >> > > which coded is Gem using to decode the mov? > if it is quicktime4linux, then the results for _decoding_ should not > differ so much. > > apart from the fact that Gem uses openGL to display the video, which is > portentially slower than xv-overlay...could you test to only decode the > videos with [pix_film], without any [pix_texture] and compare these? > and put your video-files online so other people can participate in the > review? > > > fmar > IOhannes > > _______________________________________________ > [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
