  • avformat/movenc : write the mdcv atom by default

    28 mars 2020, par Michael Bradshaw
    avformat/movenc : write the mdcv atom by default

    The mdcv atom isn't in ISO/IEC 14496-12:2015 but it is expected to be
    
added soon. See :
    
http://ffmpeg.org/pipermail/ffmpeg-devel/2020-April/259529.html
    

    The mdcv atom is already parsed in FFmpeg in mov.c.

  • React Electron ffmpeg-extract-frames build error

    28 mars 2020, par taylorallen0913

    I am using the npm module ffmpeg-extract-frames for splitting video frames. It works completely fine when I am testing the module in a vanilla node environment. However, when I import the module in my Electron React desktop app component, it gives me a error when building.

    This is how I am importing it :

    const extractFrames = require("ffmpeg-extract-frames");

    This is the error I am getting when building in my React Electron component :

    > expedition-hacks-project@0.1.0 build /home/taylorallen/Desktop/expedition-hacks-project

    I found a github issue https://github.com/fluent-ffmpeg/node-fluent-ffmpeg/issues/573#issuecomment-305408048 addressing this error, and I set FLUENTFFMPEG_COV=0 on in my build script

    My scripts :

    Setting the env variable seems to not do anything, I still get the same error.

  • FFMPEG Merge Multiple Videos : No Audio Source for one of them

    28 mars 2020, par Coach Roebuck

    I’ve written a node.js script to merge multiple video files into a single file. I’ve encountered a scenario in which no audio is provided for one of the input video files.

    I first executed ffprobe so that I can access what I’ll refer to as the "video file spec". In this scenario, I created a basic module to help me better understand my problem :

    Evaluation from all processes: [
    
  {
    
    fileName: 'input-0.mp4',
    
    isVideoAvailable: true,
    
    isAudioAvailable: false,
    
    width: 1920,
    
    height: 1080,
    
    sampleRateAspectRatio: '1/1',
    
    audioVolume: 1,
    
    duration: '13.140000'
    
  },
    
  {
    
    fileName: 'input-1.mp4',
    
    isVideoAvailable: true,
    
    isAudioAvailable: true,
    
    width: 1920,
    
    height: 1080,
    
    sampleRateAspectRatio: '1/1',
    
    audioVolume: 1,
    
    duration: '17.160000'
    
  },
    
  {
    
    fileName: 'input-2.mp4',
    
    isVideoAvailable: true,
    
    isAudioAvailable: true,
    
    width: 1920,
    
    height: 1080,
    
    sampleRateAspectRatio: '1/1',
    
    audioVolume: 1,
    
    duration: '20.280000'
    
  },
    
  {
    
    fileName: 'input-3.mp4',
    
    isVideoAvailable: true,
    
    isAudioAvailable: true,
    
    width: 1920,
    
    height: 1080,
    
    sampleRateAspectRatio: '1/1',
    
    audioVolume: 1,
    
    duration: '19.020000'
    
  },
    
  {
    
    fileName: 'input-4.mp4',
    
    isVideoAvailable: true,
    
    isAudioAvailable: true,
    
    width: 1920,
    
    height: 1080,
    
    sampleRateAspectRatio: '1/1',
    
    audioVolume: 1,
    
    duration: '9.480000'
    
  }
    
]

    This next block of code are the parameters that I’ve actually hard-coded in this case. The screen resolution and aspect ratio are manually set, as I discovered differing settings with each video I have been processing. These parameters allow FFMPEG to execute successfully under normal circumstances :

    let ffmpegParameters = [
    
  '-i',
    
  'input-0.mp4',
    
  '-i',
    
  'input-1.mp4',
    
  '-i',
    
  'input-2.mp4',
    
  '-i',
    
  'input-3.mp4',
    
  '-i',
    
  'input-4.mp4',
    
  '-f',
    
  'lavfi',
    
  '-t',
    
  '0.1',
    
  '-i',
    
  'anullsrc',
    
  '-filter_complex',
    
  '[0:v]scale=1920:1080,setsar=1/1[v0];[0:a]volume=1.0[a0];[1:v]scale=1920:1080,setsar=1/1[v1];[1:a]volume=1.0[a1];[2:v]scale=1920:1080,setsar=1/1[v2];[2:a]volume=1.0[a2];[3:v]scale=1920:1080,setsar=1/1[v3];[3:a]volume=1.0[a3];[4:v]scale=1920:1080,setsar=1/1[v4];[4:a]volume=1.0[a4];[v0][a0][v1][a1][v2][a2][v3][a3][v4][a4]concat=n=5:v=1:a=1[v][a]',
    
  '-map',
    
  '[v]',
    
  '-map',
    
  '[a]',
    
  '-c:v',
    
  'libx264',
    
  '-vsync',
    
  '2',
    
  'output.mp4'
    
]

    A comment from a different thread suggested to supply a dummy audio in cases such as mine. I’ve added that to no prevail :

      '-f',
    
  'lavfi',
    
  '-t',
    
  '0.1',
    
  '-i',
    
  'anullsrc',

    I do not know how to adjust the complex filter to account for my situation of the first video containing no audio. I’ve included the entire log below :

    When I removed the stream specifier [a0], I received a different error :

    FFmpeg Video Merge - STDERR: [Parsed_setsar_3 @ 0x7f87c7709100] Media type mismatch between the 'Parsed_setsar_3' filter output pad 0 (video) and the 'Parsed_concat_14' filter input pad 1 (audio)

    My question is how will the filter-complex value of my parameter list that I have defined be adjusted to deal with that first video, which has no audio ?
