@joseph-chircop_497308027822318 I didn't know what you meant until I tried it, but lowering the resolution from 3840x2160 to 2560x1440 also changed the encoding from H265 to H264, which helped me. Thanks for that. I don't think this is the best UX for doing that but better than nothing!

When I record the H.265 main RTSP stream (rtsp://aa:bb@192.168.23.19:554/h265Preview_01_main) on my RLC-823A with auto-tracking I get a lot of choppy images and green artifacts.

Is there any way to solve that?

Relatedly, what is the FLV url for the H.265 stream? I am able to use the following for the substream:

http://192.168.23.19/flv?port=1935&app=bcs&stream=channel0_sub.bcs&user=aaa&password=bbb

However the equivalent for the main stream does not work:

http://192.168.23.19/flv?port=1935&app=bcs&stream=channel0_main.bcs&user=aaa&password=bbb

Thank you.
