build ffmpeg

ffmpeg_qsv_cuda

windows:

1.Install msys2 from www.msys2.org.

2.Clone ffnvcodec

git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git

3. Clone FFmpeg's public GIT repository.

git clone https://git.ffmpeg.org/ffmpeg.git

4.Create a folder named nv_sdk in the parent directory of FFmpeg and copy all the header files from C:\Program Files\NVIDIA GPU Computing

Toolkit\CUDA\v8.0\include and library files from C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\lib\x64 to nv_sdk folder.

5.Launch the Visual Studio x64 Native Tools Command Prompt.

6. From the Visual Studio x64 Native Tools Command Prompt, launch the MinGW64 environment by running mingw64.exe from the msys2 installation folder.

7. In the MinGW64 environment, install the necessary packages.

pacman -S diffutils make pkg-config yasm

8. Add the following paths by running the commands.

export PATH="/c/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v10.0/bin":$PATH

export PATH="/c/Program Files (x86)/Microsoft Visual Studio/2019/Preview/VC/Tools/MSVC/14.20.27607/bin/Hostx64/x64":$PATH

export PATH="/c/Program Files (x86)/IntelSWTools/Intel(R) Media SDK 2018 R2/Software Development Kit/bin/x64":$PATH

9. Goto nv-codec-headers directory and install ffnvcodec

make install PREFIX=/usr

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/lib/pkgconfig:$PKG_CONFIG_PATH 10. //export PKG_CONFIG_PATH=/z/ffmpeg_project/mfx_dispatch/build/lib/pkgconfig:$PKG_CONFIG_PATH //unset PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

./configure --enable-nonfree --disable-shared --enable-cuda-nvcc --toolchain=msvc --enable-libnpp --enable-libmfx --arch=x86_64 --extra-cflags="-I../nv_sdk/include -I../intel_sdk/include" --extra-ldflags="-libpath:../nv_sdk/lib/x64 -libpath:../intel_sdk/lib/x64" --prefix=./build --enable-gpl

11.make -j4 erro: 其中的报错： 1.c++ 常量中有换行符

fftools/ffprobe.c(3047): error C2001: 常量中有换行符

我就把这一行ffprobe.c的3047行打印字符给注释了，两处代码：

//av_log(NULL, level, "%sbuilt with %s\n", indent, CC_IDENT);

//print_str("compiler_ident", CC_IDENT);

还有如下报错：也是因为CC_IDENT引起的，解决方法就是上面注释
