Running SMPlayer as my MPlayer (version svn 34540 (Debian Wheezy)) front end.
I have two .avi video files. Both are identical to each other except for the audio codecs used (FYI, both use the "mpeg4 (Simple Profile)" video codec). One file uses the "pcm_u8" audio codec and one uses the "adpcm_im_wav" audio codec. Note that the codec nomenclatures reported here are those reported by the
SMPlayer (and MPlayer) play the video file with said "adpcm_im_wav" audio codec just fine. However, when these players are used to play the video file with said "pcm_u8" audio codec, the video track plays faster than does the audio track. Note that said problem is not a bias-related problem, it is a rate-related problem...
It is interesting to note that both videos play fine using Parole (v. 0.2.0.2 (Debian Squeeze)). FYI, Parole is a front end for the GStreamer framework.
Any ideas as to what the problem may be?
