• CentOS 7.4.1708 : ERROR : x265 not found using pkg-config

  16 novembre 2017, par Adrian

  I’m trying to compile ffmpeg with Nvidia support following the guides on https://trac.ffmpeg.org/wiki/CompilationGuide/Centos and https://developer.nvidia.com/ffmpeg. I’ve ended up with the following command :

  PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure --enable-pthreads --disable-w32threads --prefix="$HOME/ffmpeg_build"   --pkg-config-flags="--static"   --extra-cflags="-I$HOME/ffmpeg_build/include -I/usr/local/cuda/include"   --extra-ldflags="-L$HOME/ffmpeg_build/lib -L/usr/local/cuda/lib64"   --extra-libs='-lpthread -lm'   --bindir="$HOME/bin"   --enable-gpl   --enable-libfdk_aac   --enable-libfreetype   --enable-libmp3lame   --enable-libopus   --enable-libvorbis   --enable-libvpx   --enable-libx264  --enable-libx265    --enable-nonfree --enable-cuda --enable-cuvid --enable-nvenc --enable-nonfree --enable-libnpp

  I’m getting the wonderful error

  ERROR : x265 not found using pkg-config

  looking in ffbuild/config.log reveals the following error :

  gcc version is gcc-4.8.5-16.el7.x86_64

  As per a question below : Yes - x265 is installed as per https://trac.ffmpeg.org/wiki/CompilationGuide/Centos and yes pkg-config is finding it. The compilation error makes me think that I’m missing a flag to the —pkg-config-flags optnion, but I can’t find one that works.

  Does anyone know what I should be passing to pkg-config to get it to enable x265 ?

• decode RTP with g729 audio with ffmpeg

  29 août 2022, par user1599391

  Does ffmpeg can take the g729 encoded payload packets from RTP and make a playable wave file out of it ?
if so, do I just need to create a basic binary file with just the payload bytes in it ?
thank you
