Re: [FFmpeg-user] H264 IP-camera dump causes wrong duration/bitrate

Is it possible that your camera actually captures at a lower framerate at night/in low light condition? I think framerate is fixed rate. The probrem is in frame detection. Talking about the sample, the bitrate at night has bigger than day time one. I think the frame in night doesn't need more

[FFmpeg-user] RTCP RR when streaming RTP over RTSP/TCP

Hi, I'm just looking to confirm whether or not ffmpeg sends RTCP RRs when streaming over TCP (RTP over RTSP/TCP). Sniffing the traffic seems to indicate that ffmpeg does not send them. If not, are there any plans to add such functionality? Thanks! Ralf -- This message is subject to t
