ffmpeg-rockchip 交叉编译 移植到 rk3588s QuarkPi-CA2_SDK_v1.0

下载

git clone --depth=1 https://github.com/nyanmisaka/ffmpeg-rockchip.git ffmpeg

准备 sysroot

将 QuarkPi-CA2_SDK_v1.0 生成的 rootfs.img 挂载 mnt 目录

创建目录

mkdir ~/mnt

挂载

sudo mount -o loop rootfs.img ~/mnt

修正 libm.so 软链接

sudo ln -sf libm.so.6 ~/mnt/usr/lib/aarch64-linux-gnu/libm.so

设置 pkg-config 相关环境变量

使用主机上的 pkg-config，到 sysroot 下查找 libdrm、rkmpp、rkrga 库

export PKG_CONFIG_SYSROOT_DIR=/home/lingke/mnt

export PKG_CONFIG_PATH=/home/lingke/mnt/usr/lib/aarch64-linux-gnu/pkgconfig

配置

./configure \
  --prefix=/home/lingke/projects/rk3588s_install_path/ffmpeg \
  --enable-gpl \
  --enable-version3 \
  --enable-libdrm \
  --enable-rkmpp \
  --enable-rkrga \
  --enable-libv4l2 \
  --enable-cross-compile \
  --target-os=linux \
  --arch=aarch64 \
  --cross-prefix=aarch64-rockchip1031-linux-gnu- \
  --enable-static \
  --enable-shared \
  --pkg-config=/usr/bin/pkg-config \
  --sysroot=/home/lingke/mnt \
  --extra-cflags="-I/home/lingke/mnt/usr/include/aarch64-linux-gnu" \
  --extra-ldflags="-B/home/lingke/mnt/usr/lib/aarch64-linux-gnu -Wl,-rpath-link=/home/lingke/mnt/usr/lib/aarch64-linux-gnu"

编译

make -j

安装

make install

将编译好的 ffmpeg 复制到根文件系统
