Core Hardware Acceleration Units​

The RK3576 chip integrates three key hardware acceleration units, each responsible for different stages of video processing:

• VPU (Video Processing Unit): Responsible for video decoding (e.g., H.264 hardware decoding); the core element mppvideodec invokes this unit.

• RGA (Image Acceleration Unit): Responsible for image scaling and format conversion (e.g., NV12→RGBA); can be enabled via mppvideodec parameters.

• GPU (Graphics Processing Unit): Responsible for video rendering and multi-frame compositing (e.g., glvideomixer compositing); managed by the Panfrost driver.
