error report when use GL_OES_EGL_image_external_essl3 #3585

Closed subenle-nreal closed 1 month ago

subenle-nreal commented 2 months ago

It seems that extension GL_OES_EGL_image_external_essl3 has been supported with https://github.com/KhronosGroup/glslang/pull/1044

But when I try to exec with file https://github.com/KhronosGroup/glslang/blob/main/Test/300samplerExternal.frag:
glslangValidator -C --auto-map-bindings --target-env vulkan1.1 300samplerExternal.frag

Some error is reported that seems should not exist;

What kind of SPIR-V is this supposed to be generating? Is generation of SPIR-V with this extension even supported in the first place?

I don't understand the SPIRV format; I just have a project that needs to switch from OpenGL to Vulkan, and I've found that shaders relying on this extension can't be properly converted to SPIRV.

I've tried without extension GL_OES_EGL_image_external_essl3，with YUVConversion feature, it worked fined. just close this issue.
