hi,
first of all, gem is now compiling fine under gutsy (no more problem with avifile).
what i am looking for is to playback the video back and forth, skip frames etc... there's an option when encoding with ffmpeg to put a keyframe every frame. so maybe not just jpeg codec can do the job... example:
ffmpeg -i cow.avi -deinterlace -cropleft 40 -cropright 40 -b 300 -intra cow.mpg (-intra = keyframe every frame)
will produce a mpeg1video. trying to load this movie in gem doesn't work. gem report 0 frame (it doesn't crash).
mpeg3toc cow.mpg cow.toc and loading cow.toc will crash gem.
if i load the DV (cow.avi) in gem, 35% of my cpu is used. that's not bad...
