[Saentist]

Can be added also AMD Advanced Media Framework (AMF)
AMD gpu's also can do some job

Took me a bit to figure out how to do this, so putting here to hopefully make it easier. This was added in FFmpeg/FFmpeg@f8ad2dd#diff-3adfff78d6c720bbaa2e75bd85524380 and has the basic instructions as well.

To enable support you must obtain the AMF framework header files(version 1.4.9+) from
@url{https://github.com/GPUOpen-LibrariesAndSDKs/AMF.git}.

Create an @code{AMF/} directory in the system include path.
Copy the contents of @code{AMF/amf/public/include/} into that directory.
Then configure FFmpeg with @code{--enable-amf}.

So in this case, need to add the two folders (and content) components and core from https://github.com/GPUOpen-LibrariesAndSDKs/AMF/tree/master/amf/public/include into workspace/AMF

Then add --enable-amf to the FFmpeg build

If can be added as branch for test will be good.

This script currently doesn't support zip files, so would require some additions / testing to the download function, such as:

  make_dir "$DOWNLOAD_PATH/$TARGETDIR"

  if [[ $DOWNLOAD_FILE == *.zip ]]; then 
    if ! unzip "$DOWNLOAD_PATH/$DOWNLOAD_FILE" -d "$DOWNLOAD_PATH/$TARGETDIR" 2>/dev/null >/dev/null; then
        echo "Failed to extract $DOWNLOAD_FILE";
        exit 1;
    fi
  else 
    if [ -n "$3" ]; then
    ...
  fi

Then would need some way to detect if the system has a supported AMD card, and if so then add a section like:

if build "amf"; then
  download "https://github.com/GPUOpen-LibrariesAndSDKs/AMF/releases/download/v.1.4.21/AMF_SDK_1.4.21.0-2021-07-20.zip"
      execute rm -rf ${WORKSPACE}/include/AMF
      execute mkdir -p ${WORKSPACE}/include/AMF
      execute cp -r ${PACKAGES}/AMF_SDK_1.4.21.0-2021-07-20/AMF_SDK_1.4.21.0/amf/public/include/* ${WORKSPACE}/include/AMF/build_done "amf"
fi 
CONFIGURE_OPTIONS+=("--enable-amf")

Could you please explain where is my workspace folder in ubuntu?

could be it /home/noe/ffmpeg_sources? or which?

[cdgriffith]

@Milor123 after you run the ./build-ffmpeg --build script once it will create a workspace folder, that is where it needs to go, those updates applied and then re-run (have not worked with this in two years so knowledge is rusty on it)
