## What it is
A fork of FFmpeg adding full hardware transcoding pipelines for Rockchip SoCs via MPP decoders/encoders and RGA 2D accelerator filters, with async and zero-copy DMA support. It targets devices like the RK3588/RK3588s for efficient 8K-capable video decode, encode, and post-processing.

## Use cases
- hardware-accelerated video transcoding on Rockchip RK3588
- decode 8K HEVC or AV1 video using the SoC's MPP hardware
- encode H.264/HEVC video with zero-copy DMA buffers
- scale, crop, or transpose video using the RGA 2D accelerator
- build a low-power ARM media server or NVR transcoder
- convert video pixel formats without CPU copies using AFBC

## When to choose
- you run FFmpeg workloads on Rockchip RK35xx hardware and want full hardware acceleration
- you need a complete decode-filter-encode pipeline entirely on the SoC's media blocks
- you want zero-copy DMA and async frame-parallel encoding for performance

## When to avoid
- you are on x86 or non-Rockchip ARM platforms with no MPP/RGA hardware
- you need a general-purpose FFmpeg build for software transcoding
- you require codecs beyond the supported H.264/HEVC/MJPEG encoders
