[Mesa-dev] GL_TEXTURE_2D to wl_buffer

[x414e54]

I am attempting to pass a GL_TEXTURE_2D directly to a Wayland compositor by
first converting it so an EGLImageKHR and then to a wl_buffer.

eglCreateImageKHR appears to work fine but when calling
glCreateWaylandBufferFromImageWL I get EGL_BAD_MATCH "unsupported image
format".

The GL_TEXTURE_2D is in GL_RGBA format.

Is this going to be possible or should I look for an alternative way?


I was originally blitting the texture to the default framebuffer and then
trying to use eglSwapBuffers. But for some reason eglSwapBuffers was
returning EGL_BAD_SURFACE even though eglMakeCurrent had no errors.
