编译支持 rkmpp 的 ffmpeg 实现硬解视频

• 安装编译相关工具

    # 下载开源项目源码用
    sudo apt-get install -y git
    # 常用的编译工具
    sudo apt-get install -y gcc g++ cmake make
    # 编译libva时需要
    sudo apt-get install pkg-config  
    # 构建工具
    sudo apt-get install meson
    # 部分依赖的库
    sudo apt install libdrm-dev libdav1d-dev libx264-dev libx265-dev

# Native compilation on ARM/ARM64 host

# Build MPP

# Build RGA

# Build the minimal FFmpeg (You can customize the configure and install prefix)
mkdir -p ~/dev && cd ~/dev
git clone --depth=1 https://github.com/nyanmisaka/ffmpeg-rockchip.git ffmpeg
cd ffmpeg
./configure --prefix=/usr --enable-gpl --enable-version3 --enable-libdav1d --enable-libx264 --enable-libx265 --enable-libdrm --enable-rkmpp --enable-rkrga
make -j$(nproc)

# Try the compiled FFmpeg without installation
./ffmpeg -decoders | grep rkmpp
./ffmpeg -encoders | grep rkmpp
./ffmpeg -filters | grep rkrga

# Install FFmpeg to the prefix path
make install

安装完成后查询当前FFmpeg可以调动的硬件

ffmpeg -hwaccels
