• 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 ?

• ffmpeg unexpected exit code 1 for -list_devices and -list_options

  8 janvier 2024, par djvg

  Description

  


  If I run any of the following commands from the examples in the documentation, using ffmpeg 4.2.2 on Windows 10, the requested information is successfully displayed in the console, but the process exits with exit code 1, instead of the expected 0 (success).

  


  ffmpeg -list_devices true -f dshow -i dummy

ffmpeg -list_options true -f dshow -i video="MyCamera"


  


  As far as I know, exit code 1 on Windows implies "Incorrect function", so I consider this behavior to be unexpected.

  


  If I stream camera input to disk, using e.g. ffmpeg -f dshow -i video="MyCamera" "myfile.mp4", then stop using q, the exit code is 0, as expected.

  


  Question

  


  Does the exit code 1 constitute normal behavior for ffmpeg, or am I doing something wrong ?

  


  Relevance

  


  When running the commands manually, from the command line, the exit code does not make much difference, as long as the requested information is displayed.

  


  However, when running the commands programmatically, it may cause trouble. For example, using Python's subprocess.run(..., check=True), the nonzero exit code causes a CalledProcessError.

  


  Of course there are ways around this, e.g. use check=False, but the point is that a workaround would not be necessary if ffmpeg behaved as expected, i.e. returned 0.

  


• FFmpeg add complex filter image and audio to video

  5 mars 2019, par fitzmode

  I’m working with fluent-ffmpeg for Node and would like to add a gif image and an audio to an mp4 video. The gif added with complexFilter works as expected, but the audio does not work with the complexFilter applied. Without the complexFilter, the audio works as expected.

      ffmpeg('/Users/xxx/functions/src/initialvideo.mp4')
  
      .setFfmpegPath(ffmpeg_static.path)
  
      .input('/Users/xxx/functions/src/somegif.gif')
  
      .complexFilter(
  
        [
  
          {
  
            "filter": "overlay",
  
            "options": {
  
              "enable": "between(t,0,4)",
  
              "x": "810",
  
              "y": "465"
  
            },
  
            "inputs": "[0:v][1:v]",
  
            "outputs": "tmp"
  
          }
  
  
  
        ], ['tmp'])
  
      .addInput('/Users/xxx/functions/src/somemusic.mp3')
  
  
  
      .outputOptions(['-pix_fmt yuv420p'])
  
     .on('end',() => {
  
  
  
       return response.status(200).send(`Error getting collection: `)
  
  
  
    })
  
     .on('error',() => {
  
       return response.status(500).send(`Internal Server Error: `)
  
  
  
     })
  
     .save('/Users/xxx/functions/src/finalvideo.mp4')

  Any ideas on how I can solve this ?
