[Ffmpeg-devel] FFmpeg + X264 questions

[David Shirley]

Ok fair enough - really the problem is mythtv which uses ffmpeg as I
am sure you know!

Is there a utility that will tell me if a given mpegts file (with H264
codec) is interlaced?

That way I can be sure its a playback issue rather than encoding and
report the problem to mythtv-dev's.

Cheers
Dave
