Expected Behavior
Although it is mentioned in #8522 and #10029 that YouTube does not yet support 10-bit AV1 live streaming, custom RTMP services may support it, and AV1 encoding should be allowed when using custom RTMP services.
Current Behavior
Error message: HDR output is currently disabled for this output.
Even if a custom RTMP server actually supports it.
Steps to Reproduce
- Enable 10bit/HDR settings
- Set the encoding to AV1
- Configure a custom RTMP service
- Start streaming
Anything else we should know?
I'm currently using a self-written RTMP server, and I'm not sure which existing implementations support HDR live streaming, but my RTMP server can handle HDR AV1 streams pushed using ffmpeg.

Research direction
No source file, test, or entry point is named. Start by reproducing the four listed steps with the attached OBS log, then trace the validation that emits “HDR output is currently disabled for this output”; done means custom RTMP permits HDR AV1 while unsupported services retain their restrictions.
