Hrm. Even using HandBrake I still get a file that only plays now for 10
minutes. Here's my HB command line:
HandBrakeCLI -i /storage2/3093_20150215155900.mpg -o /storage2/3093_20150215155900.mkv -f mkv -e x264 --x264-preset faster --x264-profile high --x264-tune film -q 21 -E copy --decomb --crop 60:60:0:0 -w 720 -l 360
And when done, I rebuild the seektable:
$ mythcommflag -v all --loglevel debug --nologserver --rebuild --file /storage2/3093_20150215155900.mkv

No I-frames found, rewinding...
2015-02-15 20:32:27.738431 E [matroska,webm @ 0x1ece600] File is broken, keyframes not correctly marked!

2015-02-15 20:33:37.316427 E decoding error
eno: Unknown error 541478725 (541478725)
And when I play in mythavtest it now thinks this 30 minute file is only
10 minutes log when Mplayer is perfectly capable of playing the full 30
minutes long.
