Hello Mike

 

In my particular case, I was looking for lost packets (RTSP over UDP) in
order to figure out how I should deal with those in the codec and also what
the RTCP packets were containing, since I couldn't figure out the weird data
I was getting.

 

The graphs don't tell me much either. Not only do they contain bars that
span the entire Y-axis, they also suffer from severe redraw issues, once you
zoom in on some spots... I tend to look mostly at the list of packets and
then use "Jump To" to further inspect the packets in the main window.

Subject: [Live-devel] Very large P-frames in a recording

 


Roland 

Thanks for the suggestion. We've confirmed that the large frames contain
only a single picture by searching for the MPEG-2 start codes. 

We're working on a filter that will truncate a frame when it exceeds a given
size, so that excessively large frames are not written to the file. 

What exactly do you look for in Wireshark? I can see that it recognizes the
RTP streams, but I didn't see where to get a more detailed analysis -- it's
hard for me to tell what the analysis graphs are really measuring.
