I tried to use this, but it didn't work. And I got the following log:

Hello
Which device did you use?
Please install rpms below:

1. Driver
   TV(PONTUSM, NIKEM2) ---> soc-gpu-ddk-nike-tv-23.0-0.armv7l.rpm
   RPI4 --->mesa-22.1.7-0.armv7l.rpm
2. vulkan-headers-1.3.208-0.armv7l.rpm
3. vulkan-loader-1.3.208-0.armv7l.rpm
4. vulkan-wsi-layer-1.0.5-0.armv7l.rpm

Thanks

I used TM1 and mobile emulator. both are Tizen 6.5. Why do I need to install more rpms manually?

I think you can't run vulkan on emluator. On emulator, GLES API is translated into GL API via yagl module, though vulkan is cross-platform, yagl still need to do something to forward vulkan API, I think this part isn't implemented yet.

--->Because current Tizen images didn't include vulkan related libraries and header flies

You may reopen this in https://github.com/flutter-tizen/embedder if necessary.

Can external textures be used with the Vulkan renderer?

[xuelian-bai]

no, it can't, it's not fully implemented

[swift-kim]

Yeah, it's not (yet) implemented. Is it technically possible to implement the external texture support in the future?

[xuelian-bai]

it's possible, we have implemented prototype last year, but since Impeller could be used in the future, we have suspend this implementation, and didn't fixed bugs.
On the other way, since skia is designed for opengl, even we use vulkan backend, performance may not be enhanced, Imepller is designed for modern graphic APIs(Vulkan, metal), so I guess using impeller vulkan backend will have better performance.
