Amphion Malone encoder and supported pixel formats

I know that the Hantro encoder on the i.MX8M Mini supports not only multiple YUV but also multiple RGB formats.

But what about the Amphion Malone encoder on the QuadMax? The kernel driver code indicates that only YUV formats are supported as the encoder input. Is this correct?

If so, I need a suggestion for a solution. I am composing video frames with G2D. G2D can take YUV and RGB as input, but can only output RGB formats. Is there anything on the i.MX8 QuadMax that would be able to convert from YUV to RGB formats? I'd like to avoid CPU-based format conversions, since these tend to be much slower.

i.MX8M processor series has Hantro VPU and i.MX8 series has Amphion VPU.
However I am aftaid not all formats of are supported with the driver.

Alright, thanks. Does the i.MX8 then have some sort of subsystem that could do an RGB->YUV conversion? On the i.MX6, I would have used the IPU for this, but the i.MX8 has no IPU.

ISI (Image Sensor Interface) of i.MX8 processor has color space conversion.
