Video keyframe requests #114

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi,

In order to make codecs such as H.264 work effectively, it's useful to be 
able to request the far end send a key frame (if the first few packets 
of video have been missed, or packet loss is occuring).

How we can request the Video Keyframe to the far end using libjingle (via XMPP)?
Or the video keyframe request is done via RTCP?

It's being done through the RTCP, namely, you need to send Full Intra Request 
(FIR).
Refer to RFC5104 - Codec Control Messages in the RTP Audio-Visual Profile with 
Feedback (AVPF) Section 4.3.1: http://www.faqs.org/rfcs/rfc5104.html
