Hi,
1. My cam create mpeg-ts files with h264+ac3+pgs tracks
2. I don't want to keep mpeg-ts container so I convert to matroska with these commands :
a. ffmpeg -i 00001.MTS -vcodec copy -acodec copy -scodec dvdsub -f matroska 00001.mkv # I need to convert pgssub to vobsub because a raw copy doesn't work.
b. mencoder 00001.mkv -ovc frameno -nosound -o /dev/null -sid 0 -vobsubout 00001 # I need to re-extract the vobsub track with mencoder because ffmpeg
doesn't create a sub track I can use with mkvtoolnix (no CodecPrivate).
c. mkvmerge -o file1.mkv 00001.mkv 00001.idx # I create my final file1.mkv (1: video track 2: audio track 3: vobsub track).
d. running same commands for 00002.MTS
e. mkvmerge -o final.mkv file1.mkv + file2.mkv # I want to concatenate all my two mkv files to one single file.
3. Then I can read final.mkv with subtitles (which display date) with mplayer.
But sometimes I have a problem. The video freezes for about 5 seconds where
mkvmerge concatenate files. If the final.mkv has no vobsub track, mplayer works fine. So the problem
seems to be a bug from mplayer when reading vobsub.
I can play the same final.mkv with ffplay without problem.

Sorry to not send a part of the video file. It's private.
Thanks.
