Hi there
I'm using MEncoder 2:1.0~rc2 on ubuntu 8.10
I'm trying to convert an h264/ogg .mkv video into an xvid/mp3 .avi,
according to mkvinfo my video is 2 minutes 59 seconds long, has a resolution
of 1264 x 608, and has 25 frames per second,....

It finished but sent me lots of Skipping frame! and some duplicate frame(s)
warings
Problem here is that the resulting file is shorter than the original .mkv,
it is 2 minutes 41 seconds long while the original is 2 minutes 59 seconds
long, when I play it, the video track goes a little bit faster than the
audio track, when the file reaches the end, the video track finishes but the
audio is truncated, it seems to be a muxing problem, maybe I'm missing some
option
The next thing I did, was to encode each track by extracting them from the
original mkv file....

The resulting avi file looks fine, it's 1264 x 608, XVID MPEG-4, 25 frames

The file audio_track.ogg I extracted with mkvextract is also 2 minutes 59

Looks like I can't just copy the audio track

Just like before lots of Skipping frame! warnings
The resulting file is also short, 2 minutes 41 seconds and has no audio
track, also looks like I don't have some library related to the facc encoder
(how can I very this?)
So I turned the -noskip flag on and went back to mp3lame......

Also lots of Skipping frame! warnings and the resulting file got even

Don't know what else to do
