[MKV] Why does this file not play?

[modulation]

Since my new PC has a BD-Rom Drive i just tried to rip my BluRay Movies to 720p h.264 mkvs. I use ffmpeg (latest git) on Linux to crop/scale and reencode the Movies but so far not with much success.

The movie plays back on my PC without problems but if i open the file on the NMT (latest firmware 5th April[/code]) the Screen gets black for a few seconds before it jumps back to the menu. Then i have to reboot the NMT.

I use following command line:

Code:

ffmpeg -i 00000.m2ts -threads 0 -v 3 -loglevel info -vf crop=1920:784:0:148,scale=1280:528 -sws_flags bilinear -async 1 -map 0.0:0 -map 0.3:0 -level 41 -vcodec libx264 -preset slow -profile main -tune film -crf 17 -acodec copy -alang ger -sn -bufsize 10000000 -f matroska /data/down/movies/temp.mkv

Could anybody give me a hint on what could be wrong or a working method to reencode m2ts to mkv on Linux?

---

Just found the solution. It seems the NMT can't playback lavf muxed mkv files. I remuxed with mkvtoolnix and now it works.

I have been having problems playing COMPULSION's uploads to the newsgroups. They use the LAVF encoding library.

Re-muxing solved the problem and saved me some downloading.

Thanks for the tip.
