Thanks Carl.

Sorry I wasn't clear above. The FFmpeg versions I was referring to
were the ones used to capture the video from the IP camera on a Linux
machine. I used the latest git head with ffprobe on OS X to produce
the output above.

Would the patch you suggested need to be applied to the capturing device?

I'm looking at the 'corrupted' video on OS X, so I don't think V4L
applies. I couldn't see any equivalent uses of
AVSTREAM_PARSE_FULL_ONCE to alter. Should I test on Linux instead?

Thanks again,
