Hi, the latest firmware seem to use hevc h265 for the 2560x1440 stream, and messing up with my ONVIF NVR setup, as it do not support h265. 

stream url rtsp://192.168.120.182:554/stream2
[Rebroadcast Plugin]: -hide_banner -use_wallclock_as_timestamps 1 -r 25 -rtsp_transport tcp -i rtsp:[REDACTED] -rtsp_transport tcp -vcodec copy -acodec copy -pkt_size 32000 -f rtsp rtsp://127.0.0.1:32971/f431eb34b844de3b

The firmware release note make no metion about switching codes, the product description page also not updated.

How can I switch back to H264 with current firmware, and how can I downgrade the firmware if I cannot switch back to h264.

Thanks a lot!
