RTP statistics

Postby evertek » 18 Jul 2008 23:23

I would like to get the packet loss from RTP for a streaming program I am working on. I'm using libvlc and I've gotten access to the input_item stats, but this is just generic media stream info. Does anyone know a good way to look at RTP packet loss or if there is plans to add this to the RTP module. If not, I'd be interested in looking into it, so if anyone has any information on it, please let me know. Thanks.

Unfortunately, the RTCP statistics are not currently collected by VLC.

The RTP receiver converts the RTP timestamp to the VLC clock frequency (1MHz) and stores the resulting PTS to the i_pts field of the received data block. The codec can simply read the p_block->i_pts value if it needs the RTP timestamp.

Sorry, I'm still confuse,

Where can I get sent time and arrived time of each packet in VLC Code in Client Side (not server side) ?

Thank You So Much
