Expected behavior

Actually this is the expected behavior, but can it not be though?

DistroAV/src/ndi-output.cpp

Lines 182 to 200 in 6640cb4

	case VIDEO_FORMAT_NV12:
	o->frame_fourcc = NDIlib_FourCC_video_type_NV12;
	break;
	case VIDEO_FORMAT_I420:
	o->frame_fourcc = NDIlib_FourCC_video_type_I420;
	break;
	case VIDEO_FORMAT_RGBA:
	o->frame_fourcc = NDIlib_FourCC_video_type_RGBA;
	break;

hope you're well, sorry to be a bug, I installed the current version of NDI expecting it did indeed support HDR; however, seems the plugin doesn't at this time? why is that, and do we expect this to be added? if so locating it is difficult, can it be included in the readme/OBS plugin page so people know in advance please?

Needs NDI sdk advaced, aka comercial licensing. For the time being its not supported by us.

Can we eat it as VIDEO_FORMAT_BGRA like the preview does?

DistroAV/src/preview-output.cpp

Line 131 in 6640cb4

voi.format = VIDEO_FORMAT_BGRA;

I'm sending the HDR output from one OBS instance (youtube), to another for SDR (twitch); i'm honestly new to the video part of audio video so this may be a very silly request.

[RayneYoruka]

If I don't remember wrong there was issues with BGRA and NDI (latency, sync and so on). It was discovered by a user within the discord server.

HDR is out of the question for the time being.
