[Mjpeg-users] audio sync problems

[Jean C. <et...@gm...>]

hi ...
first i like to say that problably this is a stupid question, but i have
bothering me like 2 weeks now; here is the deal im encoding a video (a
clients request to translate an a avi file to dvd) so i tried to make a
dvd format compilant but the audio is not synced, and i dont know what
im doing wrong, here is the method im using

-----------------------------------------------------------------------
for video:
mkfifo stream.yuv

cat stream.yuv | yuvdenoise | yuvscaler -M WIDE2STD -O DVD -n n |
mpeg2enc -a 2 -n n -F 4 -s -f 8 -o video.m1v&

mplayer -nosound -vo yuv4mpeg input.avi

for audio:
mkfifo audiodump.wav

cat audiodump.wav | mp2enc -V -o sound.mp2&

mplayer -ao pcm  input.avi

mixing both:
mplex -o dvd.mpg sound.mp2 video.m1v
-----------------------------------------------------------------------

it seems that somewhere its frame dropping cuz the video goes faster
than the audio track

Any suggestion will be appreciated

Jean
