[null @ 0x1d73ca0] Encoder did not produce proper pts, making some up.
[h264 @ 0x1d59420] data partitioning is not implemented. Update your
FFmpeg version to the newest one from Git. If the problem still occurs, it
means that your file has a feature which has not been implemented.
[h264 @ 0x1d59420] If you want to help, upload a sample of this file to
ftp://upload.ffmpeg.org/incoming/ and contact the ffmpeg-devel mailing
list. (ffmpeg-devel at ffmpeg.org)
