1. 安装ffmpeg

通过 apt 安装的 FFmpeg 是通用的软件版本，而 ffmpeg-rockchip 则是为 Rockchip（瑞芯微）RK35xx 系列芯片“量身定制”的硬件加速版本,支持硬件加速视频处理，包括MPP硬件编码器、解码器，以及RGA滤镜加速。

1.1 安装依赖​

在板卡执行以下命令，安装依赖：

sudo apt update
sudo apt install git meson cmake pkg-config gcc libasound2-dev libdrm-dev ninja-build libv4l-dev -y

1.2 安装MPP库​

这是 Rockchip 的媒体处理平台，它直接调用芯片内部的硬件解码器（H.264/HEVC/AV1等）和硬件编码器（H.264/HEVC）。这使得它可以轻松应对8K视频的解码或编码，而CPU几乎处于空闲状态。 在板卡执行以下命令，编译MPP库：

mkdir -p ~/ffmpeg && cd ~/ffmpeg
git clone -b jellyfin-mpp --depth=1 https://github.com/nyanmisaka/mpp.git rkmpp
mkdir -p rkmpp/rkmpp_build && cd rkmpp/rkmpp_build
cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=ON -DBUILD_TEST=OFF ..
sudo make -j$(nproc)
sudo make install

查看rkmpp解码器:

 V..... vp9_rkmpp            Rockchip MPP (Media Process Platform) VP9 decoder (codec vp9)

1.3 安装RGA库​

这是一个2D图形加速引擎。当你需要进行视频缩放、格式转换（如YUV转RGB）、裁剪或旋转时，RGA可以像“加速卡”一样瞬间完成，比用CPU处理快得多。 在板卡执行以下命令，编译RGA库：

mkdir -p ~/ffmpeg && cd ~/ffmpeg
git clone -b jellyfin-rga --depth=1 https://github.com/nyanmisaka/rk-mirrors.git rkrga
meson setup rkrga rkrga_build --prefix=/usr --libdir=lib --buildtype=release -Dcpp_args=-fpermissive -Dlibdrm=false -Dlibrga_demo=false
meson configure rkrga_build
sudo ninja -C rkrga_build install

查看rkrga:

 ... vpp_rkrga         V->V       Rockchip RGA (2D Raster Graphic Acceleration) video post-process (scale/crop/transpose)

1.4 安装ffmpeg-rockchip​

如果你使用的是RK3576、RK3588等Rockchip芯片的设备，并且需要进行高分辨率视频转码、实时流媒体处理（如搭建家庭监控、直播推流），或者希望大幅降低CPU负载，那么这个版本是唯一的选择。 在板卡执行以下命令，编译ffmpeg-rockchip：

mkdir -p ~/ffmpeg && cd ~/ffmpeg
git clone --depth=1 https://github.com/nyanmisaka/ffmpeg-rockchip.git ffmpeg-rockchip
cd ffmpeg-rockchip
./configure --prefix=/usr --enable-gpl --enable-version3 --enable-libdrm --enable-rkmpp --enable-rkrga --enable-alsa --enable-libv4l2
make -j$(nproc)
sudo make install

安装完成后验证支持情况：
