[MPlayer-dev-eng] Strange effects on Yamaha soundcard

[Bohdan Horst]

hmm strange effect on my Yamacha YMF719 card:
(on Sound Blaster not observed)
FreeBSD 4.4S, AMD 333

MI2 trailer(44kHz) recoded with ffmpeg:
ffmpeg -i  MI2.avi -b 512 -ar 44100 44.avi
ffmpeg -i  MI2.avi -b 512 -ar 22050 22.avi


RESULTS:

44kHz
-nosound: BENCHMARKs: V:   6.214s VO:   4.187s A:   0.000s (V+VO: 10.401s)
-ao oss : BENCHMARKs: V:   6.918s VO:   6.978s A:   0.744s (V+VO: 13.896s)

22kHz
-nosound: BENCHMARKs: V:   6.231s VO:   4.134s A:   0.000s (V+VO: 10.365s)
-ao oss : BENCHMARKs: V:   6.696s VO:   5.209s A:   0.507s (V+VO: 11.905s)


SUMMARY:

Video decode + Video output:
nosound: 10.4s
22kHz  : 11.9s (14% more)
44kHz  : 13.9s (33% more)


any solutions ? (maybe add downsample to mplayer will help with bad soundcards ?)

best regards
