We are developing on the Edge-V and need to be able to decode h265 and then play it. We started with kernel 4.4 and Rockchip MPP, and everything seemed to be going OK. Once we got video playing we realized that while we could decode 4k 8bit at 120fps, we got very low rendering fps because there are no GPU drivers on 4.4. So the GPU drivers seem to only support kernel 5.2 and above. We then tried to get the Rockchip MPP working on kernel 5.2+ with no luck (using fenix). There seems to be a rkvdec video decode driver for kernel 5.7+ in staging/media, but it doesn’t look like it supports h265.
So to my question.
Where do we go from here. It looks like there is no overlap between the GPU driver Panfrost and a h265 decoder driver for the rk3399. Or could I just be missing something obvious?
