ffmpeg-rockchip

This project aims to provide full hardware transcoding pipeline in FFmpeg CLI for Rockchip platforms that support MPP (Media Process Platform) and RGA (2D Raster Graphic Acceleration). This includes hardware decoders, encoders and filters. A typical target platform is RK3588/3588s based devices.

Hightlights

• MPP decoders support up to 8K 10-bit H.264, HEVC, VP9 and AV1 decoding
• MPP decoders support producing AFBC (ARM Frame Buffer Compression) image
• MPP decoders support de-interlace using IEP (Image Enhancement Processor)
• MPP decoders support allocator half-internal and pure-external modes
• MPP encoders support up to 8K H.264 and HEVC encoding
• MPP encoders support async encoding, AKA frame-parallel
• MPP encoders support consuming AFBC image
• RGA filters support image scaling and pixel format conversion
• RGA filters support image cropping
• RGA filters support image transposing
• RGA filters support blending two images
• RGA filters support async operation
• RGA filters support producing and consuming AFBC image
• Zero-copy DMA in above stages

Important

• Rockchip BSP/vendor kernel is necessary, 5.10 and 6.1 are two tested versions.
• For the supported maximum resolution and FPS you can refer to the datasheet or TRM.
• User MUST be granted permission to access these device files.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

• libavcodec provides implementation of a wider range of codecs.
• libavformat implements streaming protocols, container formats and basic I/O access.
• libavutil includes hashers, decompressors and miscellaneous utility functions.
• libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
• libavdevice provides an abstraction to access capture and playback devices.
• libswresample implements audio mixing and resampling routines.
• libswscale implements color conversion and scaling routines.

Tools

• ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
• ffplay is a minimalistic multimedia player.
• ffprobe is a simple analysis tool to inspect multimedia content.
• Additional small tools such as aviocat, ismindex and qt-faststart.
