[TESTING] Vero V: Dolby Vision TV led support

Testing

Wrong IP in your SSH? Do you have any Vero 4ks active?

I have no idea how that happened. I do have 4Ks but this is weird.
Here are the correct logs from the Vero V. These are slightly edited:

No sign of a DV-capable display in that log. Was a TV connected?

Yes. And it showed Dolby Vision on the TV when I started viewing the movies.

Thought Iā€™d do a quick test of Dolby Vision playback on my Vero-V (+ Yamaha RX-A2A/LG OLED48CX6LB)

After updating to to the development sources - ā€˜osmc-devl.listā€™ (noting that I am on kernel 4.9.269-72-osmc), I tried a couple of test files with the following results :

  1. Profile 7 - ā€˜Hybrid HDR10Plus DV Sample.mkvā€™
    The TV indicated in that it had detected ā€˜Dolby Visionā€™ (top right hand corner of the screen), however the screen remained completely blank/black with the audio playing OK.

  2. Profile 5 - ā€˜dolby-vision-amaze-(dolby-vision)-(www.demolandia.net).mkvā€™
    The TV indicated that it had detected ā€˜Dolby Visionā€™, the screen remained completely blank/black with staggered audio playback.

  3. Profile 4 - ā€˜LG Demo DolbyVision Comparison.mkvā€™
    Seemed to play OK, but TV did not detect this as DV.

The debug log is here https://paste.osmc.tv/arocabiriv and should show these three attempts.

Is there an obvious answer to this ? Do I need to adjust any settings on the TV ?

The Vero-V Player Settings were set to allow DV (i.e. HDR processing is set to HDR (Auto)).

Hi Chris

Regarding Profile 4: please see the Implementation section of my original post. This is expected behaviour.

Will check the other issues reported shortly. Thanks for the log.
