fmpeg

Here is a log I have, I need help, what's wrong here?

Consider increasing the value for the 'analyzeduration' and 'probesize' options

Answer 1

You didn't even show any arguments. I don't think there are many telepaths here.

Answer 2

You don't give ffmpeg the PPS and SPS from the h264 stream, without them it won't be able to decode it. Either this is not an h264 stream, and you set it with parameters, or you give bare frames.
