I want to make a texture from memory separated Alpha/RGB for webm(vp8) video format.
I already made an aligned ARGB data by CPU for GPU input, but the resolution is too high so it is slow.
Can I read the Alpha/RGB separated memory by EGL_LINUX_DMA_BUF_EXT or another method(vendor specific)?
Is there a way to merge ARGB using gpgpu programming to one buffer? I am sorry that I am newbie.
Any ideas would be appreciated.
