--- Comment #3 from Dongseong Hwang <dongseong.hwang at intel.com> ---

Tapani, Aditya, I think SKQP has an unnecessary restriction.

"The 2nd step" is how chromium works with media driver in following code.
https://cs.chromium.org/chromium/src/media/gpu/vaapi/vaapi_picture_native_pixmap_egl.cc?type=cs&q=VaapiPictureNativePixmapEgl::Allocate&l=72

* chromium creates regular texture
* chromium exports eglImage from the regular texture using eglCreateImageKHR
with EGL_GL_TEXTURE_2D_KHR as EGL_KHR_gl_image spec allows it.
* chromium export dma_buf from eglImage via EGL_MESA_image_dma_buf_export
* chromium gives the dma_buf to libva as external buffer.

The dma_buf can be bound in "another" egl context, so TEXTURE_EXTERNAL_OES with
the eglImage is legit in my opinion.
