Hi,
Maybe this is a corner case, but I'm trying to add an audio track to a m2v MPEG stream with Avidemux.
The problem (I think) is that the m2v file was encoded from an Avisynth script that yields a 19.75 fps progressive stream, then adds AssumeFPS(25) so that HCenc will accept it (for PAL).
The resulting m2v is then corrected with DGPulldown 19.75-->25 to run at the correct speed.
(Full story here : http://forum.doom9.org/showthread.php?t=161493 )
All this works fine, except when I try to add an mp2 (or ac3) sound track in Avidemux, using copy video and audio to MPEG PS.
The resulting MPG looks OK, except that the audio stops playing before the end of the video, although the sound track is longer than the clip itself.
The audio duration is roughly equal to 19.75/25 of the clip length, so I'm guessing that the pulldown is messing with Avidemux's calculations...
Is there any way around this, or should I use some other tool (that I haven't found yet) ?
Thanks for any hints,
