Hi,

You could try to set cricket::VideoCodec::H264()->keyFrameInterval given to webrtc::VideoEncoder::InitEncode

May I ask how to set up H264 decoding? I think the default VP8 is currently used, right？

Hi,

codec is negociate between codec supported by client and supported by server. It could be VP8 or H264 or VP9. You could use setCodecPreferences to set preferences.

In which code is setCodecPreferences set? Can you provide more details? Also, I found that when sharing the screen or reading rtsp, if it is local opencv playback, there will be no lag. If it is web playback, it will lag. Do you know why this is?

Hello, why do I lose frames when I play RTSP during the day but play smoothly at night? How can I make RTSP playback smooth during the day?
