Hi
Just purchased a Startech USB C to HDMI 2 adapter as a test really... I want to try playing back HDR graded content from my editing/colour software. I figured I'd playback some hdr content with VLC to test but although it looks good (colour space conversion seems to kick in nicely, if a bit saturated) the HDR system message doesnt seem to appear on my TV (LG) as it does with other content. I read somewhere that VLC doesnt support HDR on a mac - is this still the case? Anyone have any ideas how I can output hdr 4k material from my 2019 macbook pro? If not, struggling to see what the point of an upgraded HDMI adapter acutally is...
Thanks!

Hi, it is still the case unfortunately, we are tonemapping the video. It is mostly because the main video output on macosx is an opengl one and the main focus of apple is Metal nowadays, but it'll eventually come, we're evaluating multiple solution to bring support for it on macosx.

Thanks for your reply. VLC is awesome, by the way. Cheers

Is there any news ? nPlayer handles HDR on my 5K iMac but I don't know how they manage to do it.

What's the latest with HDR10 support from VLC on OSX Catalina to an external HDR10 display? By the way, does VLC on OSX Catalina even support RGB10 output or only RGB8 windows? It's clear OSX now supports 10 bit displays, but I'm unclear if VLC outputs 10 bit to it's GL display. Also, is there any news on OSX Metal Graphics support?

Hello People? anything new yet with RGB10 support for HDR10 external displays via VLC on OSX ??

We don't have much to announce for now. We will do a metal based video output and it will support HDR10. However, this is out-of-scope for the v3 series and will be exclusive to v4 (which will still support Catalina). For the release, I don't have a date and the work is not merged yet, so you cannot even test nightly builds.
