[Live-devel] H.264 presentation time

[Engin Kurutepe]

Hi,

The encoder configuration of your H.264 file is also important  
besides those two live555 parameters. If you are using hierarchical B- 
pictures, FFMPEG and therefore VLC do not support them correctly. In  
my experience GOP up to 8 frames works OK, but larger GOP values with  
hierarchical B-pictures can create visible decoding artifacts in  
FFMPEG/VLC, even if you set those parameters correctly.

Cheers,
Engin.
