RTSP stream from Nx server provides H263 frames even IP camera provides H.264 frames.

Hi.

A customer face the issue that RTSP stream from Nx server provides H.263 frames even the source IP camera provides H.264.

Could you support me and investigate the root cause?

Let me share result of ffprobe command with RTSP stream from Nx server and the IP camera as below.

Please check that you don't have Image rotation enabled for this camera

I confirmed that it is enabled as 180 degree.

And I confirmed RTSP stream from Nx server provides H.264 after it is disabled.

Could you fix this issue?

Thank you very much.

Hi,

The fix is scheduled to version 5.2. No terms yet for version 5.2 release.
