I noticed the fragment "Same/old NTP timestamp (1682463356176 <= 1685498991970) for incoming frame. Dropping." Is it due to the camera needing a calibration timestamp? @mpromonet

Hi, It may be camera sending b frame. You may try using option -o that doesnot uncompress or disable b frame in camera configuration. Or modifify the webrtc video decoding. Best Regards Michel

I used the option -o from the beginning,but it doesn't work. On the contrary, I didn't use the -o parameter and the console only printed some error messages, but it still played normally. In addition, I calibrated the camera clock with the option -o and the situation improved. These phenomena make me a little confused, so I need your help @mpromonet
