ERR: too many reordered frames

[cedricve]

Hey there,

I'm running one of the examples client-read-format-h264-save-to-disk using the master branch. I have the majority of my IP cameras working well, the RTSP streams read out properly, except one is throwing strange errors. Anyone an idea?

Hello, the problem here is that there's not enough bandwidth between the camera and the server, and there are a lot of lost packets. Consequently, the DTS extraction algorithm get confused since it receives incomplete frames.

Increase the available bandwidth between the camera and the server, or lower the bitrate.
