Hello,

I have a question : I haven't understand how VLC use timestamp
which are received in case of streaming of RTP stream (TS/MPEG2 over RTP).

Can you explain to me ?

Thanks a lot.

vlc can read ts over rtp in two different ways. First way (the old way) completly ignores the rtp timestamps and uses only the mpeg ts timestamps. The other way users the livedotcom module, and it somehow uses the rtp timestamps, but there are larges known problems with this way, and measures have been taken since 0.8.1 was released to reduce the chances of this module kicking in when the other module would work.

Hello Sigmung,

Thanks for your response.

Can you indicate to you where timestamp use are done in VLC ?
(In witch module).

I have 0.8.1 windows version and I don't understamp how
RTP timestamp is processed.
As timestamp is quite the main feature of this protocol,
I want to understand because I'm developping an IP set top box witch is connected a VideoLan streaming server.

Thanks

Regards

for the livedotcom module all rtp packet processing, including timestamp reading are done by the live.com streaming media library available at http://live.com
