Vulkan does not support video.

[DisDis]

my kernel, RaPi5:
Linux dslideshow1 6.12.20+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.12.20-1+rpt1~bpo12+1 (2025-03-19) aarch64 GNU/Linux

When I execute:
flutter-pi --vulkan ./flutter_assets/
I got:
Video player: flutter-pi: gl_renderer.c:582: gl_renderer_supports_egl_extension: Assertion renderer != NULL' failed.`

Video works fine in EGL mode.

I found that. flutter-pi does not support video in Vulkan mode :(

Yeah unfortunately the flutter engine does not yet support external textures (which are used to display the video frames) when using Vulkan: flutter/flutter#117937

It is technically possible to work around this by using a platform view instead of an external texture, and have flutter-pi manually composite everything together. However that's basically adding a vulkan renderer to flutter-pi. That's definitely possible but seems a bit redundant. I'd really prefer the flutter engine does the rendering, given that it has its own very capable & widely compatible rendering engine, impeller.
