Description

it's doing a swap and mirror in the cpu by default it also does the color space conversion in the CPU. we could add support for OF_PIXELS_NATIVE which would upload the pixels as they are directly to a texture and use the new facilities in the programmable renderer to do the colorspace conversion there. also the mirroring could happen there by providing it's own textures and marking them as inverted

Research direction

No file or test is named. Start by locating the DS video player and programmable renderer entry points, then determine how OF_PIXELS_NATIVE, texture mirroring, and renderer-side color-space conversion would fit; done means these CPU operations are handled by the renderer without changing playback behavior.
