Do you have a sample recording of this channel?

Can you confirm if recordings are affected or only Live TV?


Both Live TV and Recordings are affected.

I have made a fresh install of the latest stable release (2019.04-1), activated Tvheadend client addon and played the SES channel.

The channel is played back as 8 bit SDR.
A sample recording is linked below. 20MB
Meidainfo of the file shows is as 10bit.

I suspect that the channel transmissions are HLG although this is not shown in the file info and I can’t confrim this. When I toggle the HLG bit using my HDFury Vertex there appears to be more highlight detail shown on the TV.
I cannot rule out whether the earlier nightlys were ouptuting the wrong colour space. It did look much better though and I was used to it…

We haven’t added HLG support yet but it will come soon.
