Compilation

Compilation

You are free to refer to any FFmpeg compilation tutorial targeting Linux ARM/ARM64. The official tutorial is always recommended. https://trac.ffmpeg.org/wiki/CompilationGuide#Linux

The FFmpeg ./configure ... parameters are determined by personal needs. However, the following parameters MUST be additionally added to enable all functions of this project.

--enable-gpl --enable-version3 --enable-libdrm --enable-rkmpp --enable-rkrga

Important

Make sure you have built and installed the latest MPP runtime and headers. Otherwise undefined behavior may occur, such as segmentation fault. Be careful if you use MPP deb packages from a vendor/BSP image, these packages are likely to be out of date.

Examples

Assumed that all the essential libs and toolchains are installed, such as git,meson,cmake,pkg-config,gcc,libdrm-dev,etc...

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