Shield ATV HDR

[CBers 6771]

@ Which values did you change in the file header, as @@FrostByte and I have been amending both the "Video Pixel Height" and "Video Display Height" to 2160, but HDR still doesn't trigger ?

 

 

You change the display height not the video. I'll post a screenshot in a little while.

"Video Display Height" ?

[Guest asrequested]

Here you go, guys. No need to run a library scan after you save the change. Doing this has nothing to do with Emby.

Yep, that's what I did earlier, but it made no difference, HDR wasn't triggered in Emby.

Works everytime, for me

[vdatanet 1549]

For me it also works, if I set Video Display Height to 2160 it triggers HDR.

OK, I'll try again in a while.

 

You didn't need to do anything in Emby?

No, I changed the value and I played start the movie.

[Guest asrequested]

You just save the change, and play the video. No need to scan or restart anything emby.

[CBers 6771]

OK, so changing just the Video Display Height to 2160 triggers HDR now !!

[Guest asrequested]

So that's the issue. Android has to run at full screen for it to activate HDR (same as Windows). It looks like Exoplayer/shield is circumventing that by setting frame size according to the video frame. I would imagine that the other apps like plex are probably making sure that Android maintains full screen, regardless of video frame ratio.

[CBers 6771]

I wonder if somehow Plex is setting the "Video Display Height" value to 2160 before playback starts.

 

I wonder if @@ebr can do something similar.

If you were to correct this by changing that, you'd have to add padding, so that Android sees information in those last 5 pixels. Or it would just stretch the image.

[CBers 6771]

I have changed the "Video Display Height" value to 2160 on a few other samples/movies I have, but they are not triggering HDR.

[CBers 6771]

For 2 samples that do trigger HDR, are in fact stretched.

 Can you share one? Or link me to it?

I'll do it tomorrow, as getting ready for New Year now, plus I've had enough of it today

[vdatanet 1549]

In my testing, if it triggers HDR video is stretched. If HDR is not triggered video is not stretched.

 

(1) triggers hdr.txt -> After setting VDH to 2160 triggers HDR but video is stretched

(2) not triggers hdr.txt -> After setting VDH to 2160 not triggers HDR and video is not strecched

 

File (2) is supposed to be HDR, but I think it's not and obviously doesn't trigger HDR, and plex doesn't too.

triggers hdr.txt

not triggers hdr.txt

When I change the height, it stretches and enables HDR, for me

Yes, if you change the height, it stretches the video, so not a solution.

 

Still triggers HDR in Plex, even untouched.

[CBers 6771]

Did you change the VDH value in the header?

 

It won't trigger HDR as is, unless you play it in Plex.

[Guest asrequested]

Yes, if you change the height, it stretches the video, so not a solution.

I'm confused. You said;

 

I have changed the "Video Display Height" value to 2160 on a few other samples/movies I have, but they are not triggering HDR.

 

And I asked for a sample. So all of your videos play HDR when stretched?

[vdatanet 1549]

I think that Doofus does not propose this as a solution rather as a demonstration that the problem is in the crop and not in the encoding.

[Guest asrequested]

This not triggers HDR for me.

 

The display height and width on that sample have no values. Fill them both in, and try again. The whole frame needs to be filled, not just the height,
