Reading and writing YUV 10 bit texture

aki

I want to read and write YUV 10 bit texture with MALI - T 820, but I do not know how to specify it. What should I set up?

    YUV formats cannot be directly allocated and specified via OpenGL ES; you'll need to import a 10-bit YUV external EGL image (if your platform integration actually supports them) and use that.

    For reading the following extensions must be supported:

    • GL_KHR_image_base
    • OES_EGL_image_external

    ... additionally with:

    • OES_EGL_image_external_essl3

    ... if you want to use "#version 300 es" shaders

    For writing the following extensions must also be supported:

    • EXT_YUV_target

    Note: which YUV formats are actually supported and how to allocate them is OS and platform dependent; even though the GPU supports it doesn't necessarily mean that the host platform does (e.g. if the other media encoders or display controller do not understand 10-bit YUV, there is no point the GPU generating it).

    Kind regards,
