Hello,
I have (probably broken) avi file, which I want convert by mencoder. When
I try it encode using 3-pass encoding, destination file has audio delayed
(and video is some seconds shorter). Mencoder doesn't writes any warning
or error messages.
mencoder -ovc frameno -o frameno.avi -oac copy zeroframes.avi
mencoder -ovc lavc -lavcopts vcodec=mpeg4:vpass=1:vbitrate=650 -oac copy
zeroframes.avi -o zeroframes.avi.out.avi
mencoder -ovc lavc -lavcopts vcodec=mpeg4:vpass=2:vbitrate=650 -oac copy
zeroframes.avi -o zeroframes.avi.out.avi
When I try use one-pass encoding, destination file has audio OK, but
mencoder at some few positions at begin of file reports
"duplicate 1 frame(s)!!!" message for 5 - 30 frames consecutive.
(These places are exactly in positions of black screen between titles,
therefore it may not be the error, but empty frames with zero length
in source file.) When I take destination file and encode it by mencoder
again, messages about duplicated frames are the same and at the same
places.
mencoder -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=650 -v -oac copy
zeroframes.avi -o zeroframes.avi.out.avi
I think, that mencoder can't correctly process empty frames (with zero
length) in source avi file when 3-pass encoding is in progress. And in
one-pass encoding it copies zero length frames to destination file correctly, but
it writes message about duplicating frame.
I am not sure, that my ideas are right, but I can't find other
explanation.
