AMF and QSV encoders support

[Aleksid1]

Hi, I'm embarrassed to bother you again. But can you consider adding support for AMD AMF and Intel QSV video encoders?

I found the code and adapted it for your script but it doesn't link with FFmpeg, probably it's a wrong code:

amf_git="https://github.com/GPUOpen-LibrariesAndSDKs/AMF.git"
amf_release="v1.4.32"

--enable-amf

# AMD AMF (Advanced Media Framework)
do_git_checkout $amf_git $amf_release AMF
pushd AMF || exit
mkdir -p build
cd build || exit
cmake -G"Unix Makefiles" -DCMAKE_INSTALL_PREFIX=$prefix -DCMAKE_BUILD_TYPE=Release ..
make -j $threads
make install
popd || exit

msdk_git="https://github.com/Intel-Media-SDK/MediaSDK.git"
msdk_release="intel-mediasdk-21.3.5"

--enable-libmfx

# Intel Media SDK (Quick Sync Video)
do_git_checkout $msdk_git $msdk_release MediaSDK
pushd MediaSDK || exit
mkdir -p build
cd build || exit
cmake -G"Unix Makefiles" -DCMAKE_INSTALL_PREFIX=$prefix -DCMAKE_BUILD_TYPE=Release ..
make -j $threads
make install
popd || exit

I tried enable QSV and found it a bit tricky but can give it another look.

[Aleksid1]

I understand. The task is not easy. Good luck!

You need to specify a cmake cross-file. That still doesn't solve my problems, though :-) These ones are more complex to get working and Intel one seems unmaintained (no check in for years).

Here is a exanple with the cross-file:

 do_git_checkout $msdk_git $msdk_release MediaSDK
    pushd MediaSDK || exit
    mkdir -p build
    cd build || exit
    cmake -DCMAKE_TOOLCHAIN_FILE="$config_dir/toolchain-x86_64-w64-mingw32.cmake" \
        -DCMAKE_INSTALL_PREFIX=$prefix -DCMAKE_BUILD_TYPE=Release \
        -DBUILD_SAMPLES=OFF -DBUILD_TUTORIALS=OFF -DBUILD_DISPATCHER=OFF \
        ..
    make -j $threads
    make install
    popd || exit

Hi, can I try add your code above to compile libmfx and link it with FFmpeg?

[barndawgie]

I'm not sure I understand your question.

The above sample attempts to compile libmfx using the mingw toolchain, but it fails with errors that I don't really understand. Those errors appear related to the Dispatcher - which I'm not sure is needed - but disabling the Dispatcher (as shown above) results in a different set of errors.

[Aleksid1]

Thanks for your explanation. I've understood the problem.

Do you have an example of this being successfully cross-compiled in some other project?

The code above was suggested by ChatGPT 4.
I just found that BtbN uses newer Intel API - OneVPL for his cross build:
