Nvidia Shield TV 2019 (tube model) does not show video with gpu-next

[jan-kleks]

Important information

Android version: Android TV 11 32-bit

mpv-android version:

2023-11-30 Build from Google Play Store

Description

If you activate the gpu-next setting in the options, you see a solid purple screen when playing videos. One can still hear the audio, and the OSD is also visible.

This is what the log says about gpu-next when running a video: gpu_next_shield_log.txt

[sfan5]

Log is cut off.

[jan-kleks]

@sfan5 I have used "adb logcat -s 'mpv:' ':F'" to dump it. Later when it comes to errors, it just keeps repeating that it "failed rendering". Should I try to attach another one (use different options)?

[sfan5]

Sure.

[jan-kleks]

@sfan5 Hopefully, this log will have everything you need. I have even reinstalled mpv to make sure every setting is on "default".
mpv_log_full.txt

Please let me know if you need more info.

[sfan5]

That's better, though it's still cut off (run logcat first, then mpv).

maybe @haasn has an idea here about the cause
what catches my eye is that there's no reason for the uniform samplerExternalOES _8002 to be in vertex shader at all

[jan-kleks]

@sfan5 Another attempt:
mpv_opengl.txt

Also, when trying to use Vulkan it says: "setting option gpu-api='vulkan' failed" The Nvidia Shield should support Vulkan, right? Link: https://developer.nvidia.com/vulkan-android

[sfan5]

Your device sure, but not mpv-android unless you use this: #596

[haasn]

I mean, I can remove the sampler from the vertex shader if that will make the bug go away. Though it really shouldn't be complaining, since it's specified in the exact same way...

[jan-kleks]

@haasn @sfan5 If you have any test builds for me to check out at some point, please let me know! And if Vulkan 1.1 support would be enabled in such a build, I can test that as well, apart from OpenGL gpu-next.

Keep up the great work!
