Hi everyone,

I have an issue with VP8 (testing video call between Linphone application and Janus)

I figured out that, in some cases, the webrtc does not send the keyframe and I must wait for about the next 3000 frames until the keyframe is forced to send to Linphone application.

So, my question is how to adjust or force the webRTC (inside janus.js configuration) to send keyframe in an interval.

Thanks.

Sorry for my bad English.

There's nothing in the SIP plugin that requests a keyframe programmatically, you'll have to add it to the plugin yourself. Usually it's not needed because it's the other party that requests the keyframe, which I suspect Linphone is not doing.
