[Live-devel] Streaming H264: quality issue

[Christophe Lemoine]

Hi,

As I mentioned, if I play the file directly in VLC the quality is 
perfect, so VLC is probably not the issue.
Network should not be an issue as I either stream on the same PC where I 
play the video, or from a server connected on a local 100M switch.
Is there a way I can check the PCR timestamps ? Maybe I need to give 
some additional parameters to ffmpeg when I generate the TS file ?

Thanks for your help
Christophe
