change the source video framerate when pipeline is running

if this rtsp stream apply 30/1 fps at first, some how fps changed to 25/1 fps or something else which triggered the pipeline renegotiated with new caps, nvv4l2h264enc won’t produce any buffer to filesink. it’s only accept buffer on it’s sinkpad but not any buffer on it’s srcpad produced.

Can you capture the stream into TS stream or other kinds of video for us to reproduce the problem?

Can u reproduced this problem with this ts stream?

I can reproduce the issue. We will investigate the problem and get back once there is any progress.
