I thought I might redo those benchmarks:


mplayer -vfm ffmpeg -benchmark -vo null -nosound reloaded_teaser_1_640.mov
BENCHMARKs: VC:  29.901s VO:   0.016s A:   0.000s Sys:   2.624s =   32.541s
BENCHMARK%: VC: 91.8891% VO:  0.0483% A:  0.0000% Sys:  8.0625% = 100.0000%


mplayer -vfm qtvideo -benchmark -vo null -nosound reloaded_teaser_1_640.mov
BENCHMARKs: VC:  38.829s VO:   0.027s A:   0.000s Sys:   2.839s =   41.695s
BENCHMARK%: VC: 93.1270% VO:  0.0636% A:  0.0000% Sys:  6.8094% = 100.0000%



mplayer -vfm ffmpeg -benchmark -vo null -nosound trailer_final_1000_dl.mov
BENCHMARKs: VC: 180.500s VO:   0.034s A:   0.000s Sys:   5.768s =  186.303s
BENCHMARK%: VC: 96.8855% VO:  0.0183% A:  0.0000% Sys:  3.0962% = 100.0000%


mplayer -vfm qtvideo -benchmark -vo null -nosound trailer_final_1000_dl.mov
BENCHMARKs: VC: 232.988s VO:   0.045s A:   0.000s Sys:   5.976s =  239.009s
BENCHMARK%: VC: 97.4810% VO:  0.0188% A:  0.0000% Sys:  2.5002% = 100.0000%


So ffmpeg has improved quite a lot while qtvideo performance is
slightly worse.  This was latest CVS.  What puzzles me is that if I
play the complete trailer_final_1000_dl.mov qtvideo drops 1723 frames,
while ffmpeg drops 2029 frames...
