• Compile ffmpeg with x264 shows : ERROR : libx264 not found

  6 mai 2019, par NKam

  Trying to install ffmpeg from source with libx264 package. When I compile ffmpeg can’t find x264 because it is not installed.
  I followed ffmpeg installation guide.

  I tried to install and compile ffmpeg locally and found out in folder ffmpeg_build/include I don’t have x264 files installed.

  To compile libx264 I used :

  cd /ffmpeg_sources &&

  git -C x264 pull 2> /dev/null || git clone —depth 1 https://code.videolan.org/videolan/x264.git &&

  cd x264 &&

  PATH="$HOME/bin :$PATH"

  PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure —prefix="$HOME/ffmpeg_build" —bindir="$HOME/bin" —enable-static —enable-pic &&

  PATH="$HOME/bin :$PATH" make &&

  make install

  I changed url to https://code.videolan.org/videolan/x264.git, because this url https://git.videolan.org/git/x264 from guide not working

  Here how config.log’s last lines look like

  test_cflags -Wmaybe-uninitialized
  
  test_cc -Wmaybe-uninitialized
  
  BEGIN /tmp/ffconf.1LD1vklR/test.c
  
      1   int x;
  
  END /tmp/ffconf.1LD1vklR/test.c

  I want to know what I missed. I want ffmpeg to find x264, if it is not installed how can I find way to install.

• avisynth : adapt 239d02eff3ffe9f7d40caa21dde50fb4a0e94c24 to dlsym

  avisynth : adapt 239d02eff3ffe9f7d40caa21dde50fb4a0e94c24 to dlsym
  This commit was merged in a couple years ago as a no-op because we
  
  had already switched from GetProcAddress to dlsym some time before
  
  that.  However, not applying the actual cast causes warnings about
  
  FARPROC and when attempting to build FFmpeg in MSVC with AviSynth-GCC
  
  32-bit compatibility, those FARPROC warnings turn into FARPROC errors.

• avformat/aviobuf : Add ffio_init_(read|write)_context()

  2 septembre 2023, par Andreas Rheinhardt

  avformat/aviobuf : Add ffio_init_(read|write)_context()
  Most users of ffio_init_context() simply want to wrap
  
  a buffer into an AVIOContext ; they do not provide
  
  function pointers at all.
  Therefore this commit adds shortcuts for these two common
  
  operations. This also allows to accept const data when reading
  
  (i.e. the const is now cast away at a central place in
  
  ffio_init_read_context() instead of at several callers).
  
  This also allows to constify the data in ff_text_init_buf().
