Hi , I guess what this value is about because I've muxed with ffmpegX a divx (xvidffmpeg preset) file with ac3 audio and I can't hear any sound with VLC or QT(ac3 and divx component installed). Then I muxed the same two files wit D-vision 3.0 and it worked.
The only difference is about the sample value in the audiocodec info, which is -0 for the file muxed with ffmpegX and -2 for the file muxed with D-vision.
Any idea?
