Support render texture for Vulkan+Impeller #129

xiaowei-guan · 2025-11-12T09:44:27Z

If want to render texture with Vulakn + Impeller, you should apply this flutter-tizen/flutter#17

* modify_code * Type conversion * code format

xiaowei-guan · 2025-11-14T09:42:52Z

1.Add GetDevice method insted of device_ variable. 2.Refactor variable name for pixel buffer. 3.Add GetMemoryFDProperty method insted of variable.

@JSUYA
Please use pixel_buffer_test to verify render pixel buffer texture on RPI device

xiaowei-guan · 2025-12-22T07:04:05Z

@JSUYA
I have upload pixel_buffer_test to verify render pixel buffer on RPI device, please check, thank you~

JSUYA · 2025-12-22T08:08:21Z

thanks, I will check it out.

Has this issue been resolved? Is it something we can ignore at this PR?

xiaowei-guan · 2025-12-22T10:35:36Z

During the rendering process, the Flutter app process may be killed because the GPU memory is exhausted.
This isn't a embedder issue, it's a impeller or kernel issue. I am viewing the impeller code.

xiaowei-guan · 2025-12-22T12:07:35Z

I have fixed the gpu memory leak issue flutter-tizen/flutter#21

for this issue, could you please share the image version ? I will try to reproduce this issue.

…render-texture-002

JSUYA · 2025-12-23T04:29:53Z

Here is my rpi5(x64)'s binary info

[Version]
Model=Tizen10.0/Unified;
Build=tizen-10.0-unified_20251105.210909;

The issue occurred when running the example of video_player and playing the video.
If the problem does not occur with the latest binary, it may be an issue with my environment.

xiaowei-guan · 2025-12-23T06:18:41Z

This is my image version:

root:~> cat /etc/info.ini
[Version]
Model=Tizen10.0/Unified;
Build=tizen-10.0-unified_20251209.112952;
Release=20251209.112952;

But I don't have RPI5, I just have RPI4.

JSUYA · 2025-12-23T06:25:50Z

Does this issue not occur on RPI 4?
I'll update the binary to the latest version and test it.
Could it be a difference between RPI5 and RPI4?

If this is only an RPI5 issue, I think, it would be better to merge this PR and make this issue as a known issue.

xiaowei-guan · 2025-12-23T07:03:21Z

RPI4 and RPI5 use different kernel , I will try to update a aarch64 image to check this issue.
