Hello,


Thanks for helping to look into this!

OK, here are the characteristics of one particular clip.

(This is not even the worst one, I think: the 50-fps clips recorded by my 
camcorder are played back even more slowly. I don't have one of those at hand 
right now, though. Will post later.)

Format: AVC
Format profile: High at L5.1
Resolution: 1920x1080
ReFrames: 16 frames
Nominal bitrate: 11.3 Mbps
Frame rate: 23.976 fps

mplayer -va vaapi -vo vaapi -fs

Is this OK?


Kind regards,
