• Vcpkg building FFmpeg with libxml2

  15 décembre 2019, par Subestima

  First off all im a newbie in this area so if im asking something really stupid or non sense im sorry in advance, so lets get right to the point... im trying to add features to the ffmpeg, and by what i know i have to modify CONTROL file and portfile.cmake but as it seems its not enough i dont understand the errors and i cant get more info about this in the internet so if you could give me some info how to do it properly it would allready mean a lot to me ! i will leave the portions of code and error file

  **portfile.cmake:**
  
  if("libxml2" IN_LIST FEATURES)
  
      set(OPTIONS "${OPTIONS} --enable-libxml2")
  
  endif()
  
  
  
  **CONTROL:**
  
  Feature: libxml2
  
  Description: Libxml2 is the XML C parser and toolkit developed for the Gnome project (but usable outside of the Gnome platform)

  **Command Prompt after (vcpkg install ffmpeg[libxml2]:x64-windows)**

  If you think configure made a mistake, make sure you are using the latest version from Git.  If the latest version fails, report the problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "ffbuild/config.log" produced by configure as this will help solve the problem.

  Thank you for your attention,

• Compiling ffmpeg with NVDIA GPU enabled for windows

  12 octobre 2017, par Guru

  I am working on decoding video using ffmpeg with NVDIA GPU enabled on windows platform.

  Followed below steps as per the document provided by ffmpeg to compile ffmpeg software

  1. Install msys2 from www.msys2.org.
  2. Clone FFMPEG’s public GIT repository. git clone https://git.ffmpeg.org/ffmpeg.git
  3. Create a folder named nv_sdk in the parent directory of FFMPEG and copy all the libraries from C :\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\include to and C :\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\lib\x64 to nv_sdk folder.
  4. Launch the Visual Studio x64 Native Tools Command Prompt.
  5. From the Visual Studio x64 Native Tools Command Prompt, launch the MinGW64 environment by running mingw64.exe from the msys2 installation folder.
  6. In the MinGW64 environment, install the necessary packages. pacman -S diffutil make pkg-config yasm
  7. Add the following paths by running the commands. export PATH="/c/Program Files (x86)/Microsoft Visual Studio 12.0/VC/BIN/amd64/" :$PATH export PATH="/c/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v8.0/bin/" :$PATH
  8. Go to the FFMPEG installation folder and run the following command. ./configure —enable-nonfree —enable-nvenc —enable-cuda —enable-cuvid —enable-libnpp —extra-cflags=-Ilocal/include —extra-cflags=-I../nv_sdk —extra-ldflags=-L../nv_sdk
  9. Compile the code by executing the following command. make -j 8

  But In the 8th step I am getting below error, please let me know what could be the possible solution for the issue.

  admin@ADMIN-PC MINGW64 /c/ffmpeg
  $ ./configure —enable-nonfree —enable-nvenc —enable-cuda —enable-cuvid —ena ble-libnpp —extra-cflags=-Ilocal/include —extra-cflags=-I../nv_sdk —extra-ldf lags=-L../nv_sdk
  gcc is unable to create an executable file.
  If gcc is a cross-compiler, use the —enable-cross-compile option.
  Only do this if you know what cross compiling means.
  C compiler test failed.

  If you think configure made a mistake, make sure you are using the latest
  version from Git. If the latest version fails, report the problem to the
  ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
  Include the log file "ffbuild/config.log" produced by configure as this will hel p
  solve the problem.
