HDR playback and framerate match issues
HDR
I like your program very much
I use your program on two andriod devices and same Tv samsung 2021 qled q70a hdr 10
1- mibox s : when I use hdr apple Aerial videos it keeps give me black screen
2- nvidia shield : when I use hdr apple Aerial videos it plays but without activated hdr feature so colors are washed , despite of when I play same videos on any media player on nvidia shield hdr activated and color works well with no problem
SDR Apple Aerial Videos works great on mibox and nvidia shield
Framrate match
when screensaver start during I am pausing a video from player that support framrate match like plex or nova ,, it keeps play on the same framrate of the video ,, it is mostly 24 fps because most movies are 24 fps ,, and when that happen video keeps judder ,, If you can find a way to prevent that it will be great
I'll address the HDR-related questions first.
For HDR to work, you need a few things a) a HDR capable TV b) HDR playback device and c) HDR video. That seems simple enough but the problem is that there are different standards,. So different TVs, Android TV devices and videos don't always work together.
I think you're running into a few problems...
- Your new Samsung TV supports HDR but not Dolby Vision
- If you're seeing a black screen when trying to play HDR videos on tour Mi Box it likely means they didn't license the Dolby Vision codec. You can confirm this by looking in Settings > Capabilities for "dolby-digital.decoder". My guess is that Nvidia Shield has it but the Mi Box does not
- Apple's videos use Dolby Vision and not HDR10
So Dolby Digital support is required in everything for it to work. Otherwise, you'll have to stick with SDR.
In regards to frame-rate match, I wrote about it in another issue but basically it's not a standard Android feature yet - it's experimental on the Nvidia Shield and Fire TV devices so it will require more research.
it seems that I have to wait for android tv 12 to use your app ,, because my main used app are nova and it supports framerate match , when screensaver start during I am pausing a video it keeps play on the same framrate of the video ,, it is mostly 24 fps because most movies are 24 fps ,, and when that happen video keeps judder ,, if you can force your app to play on 60 fps it will be great and make it usable now

And I think part of the issue is that apps that use framerate match (in its current experimental state) can cause problems with other apps like this.
My guess is that Nova doesn't disable framerate match when paused/suspended so this issue might be fixed by a) reporting this issue to Nova as well and b) I can try adding some framerate match test code in future?
if nova disable framerate match when paused then it have to rematch frame rate every time I pause the video and this make screen blank for second ,, I think the right is too make your app to force screen to play on 60 fps
or
we have to wait for android tv 12 that will support frame rate match on the whole system like apple does
It looks like I can implement this without too much trouble, but you will have to enable it specifically.
This is how I think it'll work (also please know that I can't test this myself, only guess!)
- Nova starts playback, movie is 24fps, Nova requests 24fps from TV
- If TV accepts, screen flash black briefly (or shows some info to suggest mode change) and movie plays
- You pause movie and leave it paused for set amount of time so screensaver activates
- Aerial starts, gets video fps (usually 30) and requests mode from TV - playback starts regardless
- When screensaver is interrupted, Nova re-starts playback, re-requests 24fps, another brief black screen, then playback continues...
Very good one if you can make it ,, it will be perfect ,, all I want that your program check that tv on right fps when start
@Hotboy1987 For your Shield, have you tried app Refresh Rate ? You can configure it on a per-app basis. So if you only configure it for Aerial Views (set its default refresh rate at app start to 59.940 Hz probably), it should fix your problem I think.
A small update. It does look like Android 12 will bring in broad support for a) frame rate matching and b) VRR for TV and devices that support it. This might be the better and easier option for me.
The player I use, ExoPlayer, now supports this feature in Android 12 - ie. if you're watching a movie at 24fps then pause it, when Aerial Views launches, the player will see that the Apple video is 30fps and request a refresh rate change. There will also be a system setting for this which Aerial View will follow.
So kinda good news, but it'll be a few more months I'm afraid.
Waiting for this update ,, thx for your effort

Just a small update, more devices have Android 12 now including both Chromecast with Google TV (HD and 4K) - so I'll look at adding the 'frame rate switching' in the next update or two.
I currently have no way to test it myself, so I may issue a beta or two on here first.
Let me know when you have a beta, I'll be available for testing. I am kind of curious how it's going to play out if the app changes the frame rate from a paused video that had frame rate matching, how the OS will react when it goes back and unpauses the video at a different frame rate. I guess in theory the OS should set it back with no issue, but we will see 🙈
My current guess is that the screen will flash black briefly when the refresh rate changes.
I'll see if I can put together a beta in the next couple of weeks.
Also, just to say this again - it requires an Android TV or device running Android 12 - so the Google TV or Sony TVs (maybe others too?)
Yeah that's happen to me when screensaver starts when I am using nova player that's support auto refresh rate

I had a bit of free time so I've put together a test version of the app: (link removed)
Do let me know how you get on @hunterzero99 and @Hotboy1987 ...
Sure man ,, I will test it today and let you know

For the moment it's Android 12 only but I'll try and add support for 11 or less in the next beta.
Waiting for you

I tested out the beta you posted, my HDMI receiver shows that Aerial Views is giving a 60 fps signal instead of 29.97 (or 30 fps). I've tested on SmartYouTube and Plex switching from a 23.97 fps video to Aerial, it does work switching from the 23.97 fps to 60 fps for Aerial when paused, then it switches back to 23.97 fps when Aerial closes.
I think that's the correct behaviour. When playing 30fps content, a TV will be at a min. refresh rate of 60hz - there is no 30hz mode as far as I'm aware.
For 24fps content, even older TV have a 24hz mode and I think newer TVs might switch to 48hz as they have additional processing modes (eg. black frame insertion)
So, from your point of view, does video playback look correct and smooth - both in Aerial Views and when you return to Plex, SmartTube, etc ?
Yes, playback looks correct and smooth when switching back and forth. Nice work!
Ok, here is a new beta which should change frame rate under Android 11 or lower: (link removed)
I try your beta and it seems that it doesn't work ,, I paused nova app on video when I use refresh app to adjust the frame rate video ,, but when screensaver starts it show loading title and then it cancel and get back to the app and start video

Thanks for testing that beta. It seems like it's crashing, but I think I know the cause. I'll try and get another beta out soon.
EDIT: I got the crash report, so that confirms what I have to fix.
I would be interested in beta testing the Android 11 version on my Shield TV Pro 2019 when you have another ready to test.
Been dying for frame rate match. I easily notice judder in my 4K Drone Landscape videos I got from YouTube.
I would be interested in beta testing the Android 11 version on my Shield TV Pro 2019 when you have another ready to test.
There was a crash bug in that last beta as I can't test the feature at the moment.
I should have a new build in the next few days which may fix the issue.
Sorry about the delay, here is a new build to test: (link removed)
This build should fix the crash on Android 11 (or less) devices but it probably won't change the frame rate.
If this build a) doesn't crash but also b) doesn't change the frame rate, I have another fix which should work.
Great job man ,, I try this one and it works perfectly ,, I try it with nova player and nplayer and I use refresh rate app to auto adjust frame rate ,, and when I pause video and screensaver starts now it adjust frame rate to 30 fps and it stay like that so next video on screensaver now not blinking like before ,, you made my day ,, thx man

I have installed this beta. Fantastic work. I have about 90 4K Landscape Drone videos and so far so good. I have started the screensaver and rotated through my videos. I haven't noticed any judder from incorrect framerate.
I do have one questions. Once the screensaver is running. And it switches to a new video. If that video has a different frame rate, does this version also change to the new videos framerate? Or does it only change on the first initial video and is then locked to that framerate on subsequent videos?
All in all fantastic work. I think all of my landscape videos are 24 frames. Which is why I was asking the question. In case I ever get 30 or 60 fps videos.
That's fantastic to hear @Hotboy1987 and @Eagle00Eye
Can you both confirm what devices you're using and what version of Android they are running?
How it works - every time a video starts playing, I try to get the frame rate, then check if the window/screen is running at that refresh rate and change it if needed.
When will it be released - the next major update is v1.4.0 which is due soon so I hope to add these changes to v1.4.1 but that might be a month or two away. In the meantime, feel free to keep running the v1.3.3 beta if it fits your needs!
