4k on Android

Post #1 of 9 (866 views)

On my linux desktop, I see that it seems to be playing back at 4k
resolution:

2020-10-09 13:14:25.570360 I VideoWin: Window using screen DP-0 3840x2160
2020-10-09 13:14:25.570366 I VideoWin: Window Rect: 3840x2160+0+0
2020-10-09 13:14:25.570370 I VideoWin: Display Rect: 3840x1600+0+280
Aspect: 1.77778
2020-10-09 13:14:25.570373 I VideoWin: Video Rect: 3840x1600+0+0
Aspect: 2.4

But on android (FireStick 4k), it seems to only be HD:

2020-10-09 14:31:01.314 7940-7964/org.mythtv.mythfrontend I/mfe:
videooutwindow.cpp:102:PopulateGeometry VideoWin: Window using screen
1920x1080
2020-10-09 14:31:01.315 7940-7964/org.mythtv.mythfrontend I/mfe:
videooutwindow.cpp:486:PrintMoveResizeDebug VideoWin: Window Rect:
1920x1080+0+0
2020-10-09 14:31:01.316 7940-7964/org.mythtv.mythfrontend I/mfe:
videooutwindow.cpp:490:PrintMoveResizeDebug VideoWin: Display Rect:
1920x800+0+140 Aspect: 1.77778
2020-10-09 14:31:01.317 7940-7964/org.mythtv.mythfrontend I/mfe:
videooutwindow.cpp:494:PrintMoveResizeDebug VideoWin: Video Rect:
3840x1600+0+0 Aspect: 2.4

Is this expected? Or do I not have something configured correctly? I
know the wiki said 4k wasn't possible but it also seems like part of
that page is out of date.

Currently mythfrontend on android resizes the video to 1920*1080 even
when using a 4K TV.

Peter does the Leanfront frontend playback 4k OK?

Yes.

That is the main reason I did leanfront.

Peter, I'd like to confirm. If my Shield TV is showing as connected to
my UHD 4K TV at 3840x2160 @60 then Leanfront will play a UHD video at
full resolution??

I just tested UHD Samsung - Dive to new world- which is 3840x2160 Codec:
HEVC, Audio: AAC 2.0

It looks great, but I can't tell much difference in it from what I see
when Android mythfrontend plays it.

My old eyes think both are good.

Correct. I have some sample videos to demonstrate. Try the sample on
http://4ksamples.com/ The sample called "4K UHD Fireworks Sample".
Starting at 20 seconds in, there is very small writing in the bottom
right hand side, which looks crystal clear in 4K but jagged in 1080 (you
have to put your eyes near the screen to read the small writing).

I also have some 60fps 4K video that plays perfectly.

Is the Amazon fire tv stick 4k man enough to run Leanfront in 4k?

I don't have a 4k TV myself but my parents just bought one.
Unfortunately they chose a Samsung smart TV with Tizen OS so I'm just
looking at the options - not that they have much 4k stuff to play but
now they have a 4k TV it would be silly not to use it to it's best
potential.

Tizen OS frontend anyone :) That's an interesting project in itself. It
looks like nearly everything is just a glorified webpage \0/

I have that exact setup. A Samsung Smart TV with an Amazon Firestick 4K.
It runs just fine.

I looked at converting an Android project of mine to Tizen but I
couldn't even get their dev environment to install and run correctly, so
I gave that up within minutes. It probably works great on Windows, which
I don't have.
