Assert in tvOS

[andrefmsilva]

I get an assert when i try to run MPV in tvOS with support for vulkan.
I'm using latest commits of libplacebo, mpv and MoltenVK, but if i downgrade to some stable tag idon't get the assert but it fails to generate the texture with:

[MPV Log] [vo/gpu/libplacebo] error: Found no memory type matching property flags 0x0 and type bits 0x3!

b63864e should fix this

[andrefmsilva]

i will recompile everything but i'm already using latest commit in master 52314e0

I tried to revert back to tag v6.338.1 and i don't get the assert but i get this

[MPV Log] [vo/gpu/libplacebo] error: Found no memory type matching property flags 0x0 and type bits 0x3!
[MPV Log] [vo/gpu/libplacebo] debug: Freeing slab of size 2048

and a blue screen.

[andrefmsilva]

@haasn i've recompiled everything and the problem is only in tvOS. iOS is working

[andrefmsilva]

@haasn what do you need to help you fix this problem? it is working for iOS so it must be some small thing that is broken for tvOS.
Now that we have mpv working with libplacebo + vulkan in mac and iOS i really want to have it for all apple platforms :)

[haasn]

From your log, the biggest issue I see is that the available memory size is reported as 0:

[MPV Log] [vo/gpu/libplacebo] v: Memory heaps supported by device:
[MPV Log] [vo/gpu/libplacebo] v:     0: flags 0x1 size     0
[MPV Log] [vo/gpu/libplacebo] debug: Memory types supported by device:
[MPV Log] [vo/gpu/libplacebo] debug:     0: flags 0x1 heap 0
[MPV Log] [vo/gpu/libplacebo] debug:     1: flags 0xf heap 0
[MPV Log] [vo/gpu/libplacebo] debug:     2: flags 0x11 heap 0

I don't know, however, how this could lead to the assertion, which should just be completely impossible. (We explicitly set ubo_size to min(ubo_size, max_buf_size))

[andrefmsilva]

i will try to setup some demo app where i can add breakpoints to libplacebo and check why it fails to get that info.
@karelrooted do you already have this setup? if yes can you do a quick check why it fails to get that info?

[karelrooted]

with the latest git master , there is no assert on my env though [Apple TV 4K 2017 (tvOS 17.2) (vo=gpu-next) ]

• libplacebo version: git latest 52314e0
• MoltenVK version: v1.2.6 git latest 5bd65fc8e8b
• mpv git latest + @tmm1 's molten vk context PR (compiled code)

available memory size is reported as 0 too, mpv play the video file with audio but no video

here is the fulllog

[karelrooted]

it seems the memory heap size 0 in tvOS is hardcoded in MoltenVK/Common/MVKOSExtensions.mm#L112

after fix the memory size to return correct value, the bug is fixed, and the video plays fine, please update MoltenVK to the latest git

if use old device , you probably want to change profile to fast, basic on a quick test, the performance on Apple TV 4K 2017 is poor with default profile, when play a 4k dolby vision demo video , a lot of frame drop in output, mpv log

after change profile to fast, the video play fine with no frame drop

by the way ,while we are here, the Xcode debug mode sigabort error issue is happened too in this vo=gpu-next mode (similar, but not in the same code) , I can't get the macOS version running against official Vulkan SDK to work, is there any other way to enable VVL without using official SDK?

[andrefmsilva]

thanks @karelrooted! Really nice progress that you got here

[andrefmsilva]

@karelrooted I did a search for MKV_TVOS in Molten source code and looks like we need to change a few things. If i get some free time in the weekend i'll try to use their iOS logic for tvOS
