Hi,
I have a use-case where NV12 video frames are imported as GL texture (using EXT_image_dma_buf_import, dma_buf) and would like to down-scale the said texture into also a destination NV12 buffer (render target). The destination NV12 buffer will hold 2x2 scaled-down video frames (a mosaic).
Is this doable on Mali400? If so, is it possible to explain the necessary setup + fragment shader to use?
(E.g. the quite new EXT_YUV_target extension for gles3.0 would help achieve that?)
Best regards,
Ilyes Gouta
As stated above, to render to texture, FBO... this is only supported from r7p0 driver onwards. This support is not included in drivers prior to this.
Kind Regards,

Thanks Michael.
