• Connect ffmpeg to Visual Studio 2008

  29 avril 2014, par user2274492

  I try to connect ffmpeg to visual c++ like this, but when I type "./configure —toolchain=msvc" I have this error :

  c99wrap cl is unable to create an executable file.

  If c99wrap cl is a cross-compiler, use the —enable-cross-compile
  option. Only do this if you know what cross compiling means.

  C compiler test failed

  config.log :

  WARNING : pkg-config not found, library detection may fail. mktemp -u
  XXXXXX ./configure : line 728 : mktemp : command not found WARNING :

  /tmp/ffconf..ZHENYA.500.5884.c fatal error C1510 : Cannot load language

  What’s the problem ? Or just send me files that you got after compilation with this (I would not have asked, but I fix this two months) :

  ./configure —toolchain=msvc

  make

  make install

• avcodec : add D3D12VA hardware accelerated H264 decoding

  5 décembre 2023, par Wu Jianhua

  avcodec : add D3D12VA hardware accelerated H264 decoding
  The implementation is based on :
  
  https://learn.microsoft.com/en-us/windows/win32/medfound/direct3d-12-video-overview
  With the Direct3D 12 video decoding support, we can render or process
  
  the decoded images by the pixel shaders or compute shaders directly
  
  without the extra copy overhead, which is beneficial especially if you
  
  are trying to render or post-process a 4K or 8K video.
  The command below is how to enable d3d12va :
  
  ffmpeg -hwaccel d3d12va -i input.mp4 output.mp4
