I would upload the file to the FTP (it’s too big to attach here), but upload.ffmpeg.org seems down at the moment. You can reproduce this with any file with h264 video though.

was it merged into ffmpeg2.0 branch?

Replying to tborisow:

Yes, it is fixed in the 2.0.2 release.

comment:9 by Vit, 11 years ago

Seems this error still not fixed completely. I have part of h264 video encoded by Format Factory 3.1.1 and see almost the same error. The same happened with every of 5 tested h264 files from Internet, some of them I have re-encoded by Format Factory and HandBrake, but nothing changed. See h264-file in attachment above.

The sample you uploaded contains exactly one keyframe (the first one), -skip_frame -nokey does not make much sense for this sample / works fine.

comment:12 by Carl Eugen Hoyos, 11 years ago

If you only want to report that -skip_frame -nokey shows warnings, please open a new ticket, the warnings were shown since forever, this ticket was about a regression that affected the actual functionality of the option.
