Apologies for top post, but there's not a good place to insert this
post, since I don't have a direct response for your issue below.
I did come up with a solution a year ago that worked pretty well for
converting MKV into AVI (without recoding). This is what I did:
for file in *.mkv; do
newf=`echo ${file/.mkv/.avi}`;
tmpf=`echo ${file/.mkv/.tmp.avi}`;
gst-launch-0.10 -m -v -T filesrc location="${file}" ! \
matroskademux name=d d.audio_00 ! queue ! faad ! lame ! \
m.audio_00 d.video_00 ! queue ! m.video_00 avimux name=m ! \
filesink location="${tmpf}";
avidemux --force-b-frame --load "${tmpf}" --audio-codec COPY \
--video-codec COPY --fps 23.976023 --rebuild-inex \
--output-format AVI --save "${newf}" --quit;
rm "${tmpf}";
done
Perhaps that's useful to you?
