the best playback I can obtain is with -demuxer lavf -mc 10, and even so
either the lavf demuxer ot the lavc decoder complains of wrong
Since interlaced H264 is so complex the native demuxer doesn't have a
chance to set timestamps correctly, so the lavf demuxer is the only way
to go, I'm afraid.
IIRC the decoder corrects the video pts, but unfortunately it doesn't
seem to be enough to use the native demuxer.
