I apologize if there are any mistakes in my English writing.

I have analog clock movie.


This movie encode H.264, Mpeg-TS formats.
This file played 'Windows Media player', smoothly.
I execute 'ffmpeg -i clock.ts -f image2 %5d.jpg' from command line.
jpeg file is not smooth seconds hand.
seconds hand of 00057.jpg is back to 00056.jpg.
00087.jpg, 00117.jpg too.

I found error code
[h264 @ 047928C0] error while decoding MB 72 67, bytestream xx
[h264 @ 047928C0] cabac decode of qscale diff failed at xx xx
[h264 @ 047928C0] Reference 2 >= 2
But, output timing is not there jpeg make it.

What am I doing wrong?

Best Regards,
