> there remains a problem with converting raw NV12 to DMABufs

Could you clarify what you mean by this? With the 550 driver it should be possible to allocate an NV12 GBM buffer and export it as a pair of DMA-BUFs. Note, though, that support for this format in our EGL driver is "external only". So if an NV12 buffer is imported as an EGLImage, that image can only be bound to GL_TEXTURE_EXTERNAL_OES (not, for example, GL_TEXTURE_2D). Could that maybe be the problem?
