• How to add custom configure option with VCPKG when building FFMPEG ?

  1er novembre 2024, par NickWuzh

  Does anyone know how to enable x11grab format in FFMPEG with VCPKG ?

  


  I'm building FFMPEG in vcpkg manifest mode. Here is my vcpkg.json :

  


  {
  "name": "project",
  "version": "1.0.0",
  "dependencies": [
    {
      "name": "ffmpeg",
      "features": [
        "avcodec",
        "avdevice",
        "avfilter",
        "avformat",
        "bzip2",
        "ffmpeg",
        "lzma",
        "postproc",
        "swresample",
        "swscale",
        "x264",
        "zlib"
      ]
    },
    "iniparser",
    "jsoncpp",
    "spdlog"
  ]
}



  


  And I want to enable x11grab configuration in order to capture screen in Linux, but I found no feature was adapted.
Soon I found that —enable-libxcb was needed in configure and it was autodetect. So I build and install libxcb with source. And pkg-config can find it :

  


  $ pkg-config --modversion xcb
1.17.0


  


  But it doesn't work because in default it is —disable-autodetect in $VCPKG_ROOT/ports/ffmpeg/portfile.cmake :

  


  set(OPTIONS "--enable-pic --disable-doc --enable-debug --enable-runtime-cpudetect --disable-autodetect")


  


  I try to modify $VCPKG_ROOT/ports/ffmpeg/portfile.cmake —enalbe-autodetect, but it doesn't work either. Here is the short message when appling vcpkg install --triplet x64-linux-release

• How to combine 100 video clips with transition using FFMPEG ? [closed]

  17 octobre 2024, par Muhammad Lutfi Rahmawan

  I've been working on project which involves FFMPEG to process video. The goal is to produce a video from several clips and combine them with transition to each clips. We've succeeded to create video from 20 clips and 19 transitions are applied to merge each clips. But when it comes to a larger amount of clips, say 50, it becomes be failed.

  


  The first thing we do is split the original video into several clips based on user selection and this command is successful (log splitting). Then we combine the clips with transition using below command.

  


  Here is the sample command of FFMPEG which failed :

  


  ffmpeg -y -i /tmp/0.mp4 -i /tmp/1.mp4 -i /tmp/2.mp4 -i /tmp/3.mp4 -i /tmp/4.mp4 -i /tmp/5.mp4 -i /tmp/6.mp4 -i /tmp/7.mp4 -i /tmp/8.mp4 -i /tmp/9.mp4 -i /tmp/10.mp4 -i /tmp/11.mp4 -i /tmp/12.mp4 -i /tmp/13.mp4 -i /tmp/14.mp4 -i /tmp/15.mp4 -i /tmp/16.mp4 -i /tmp/17.mp4 -i /tmp/18.mp4 -i /tmp/19.mp4 -i /tmp/20.mp4 -i /tmp/21.mp4 -i /tmp/22.mp4 -i /tmp/23.mp4 -i /tmp/24.mp4 -i /tmp/25.mp4 -i /tmp/26.mp4 -i /tmp/27.mp4 -i /tmp/28.mp4 -i /tmp/29.mp4 -i /tmp/30.mp4 -i /tmp/31.mp4 -i /tmp/32.mp4 -i /tmp/33.mp4 -i /tmp/34.mp4 -i /tmp/35.mp4 -i /tmp/36.mp4 -i /tmp/37.mp4 -i /tmp/38.mp4 -i /tmp/39.mp4 -i /tmp/40.mp4 -i /tmp/41.mp4 -i /tmp/42.mp4 -i /tmp/43.mp4 -i /tmp/44.mp4 -i /tmp/45.mp4 -i /tmp/46.mp4 -i /tmp/47.mp4 -i /tmp/48.mp4 -i /tmp/49.mp4 -filter_complex "[0:v][1:v]xfade=transition=circlecrop:duration=0.5:offset=24.474[tv0];[0:a][1:a]acrossfade=d=0.5[ta0];[tv0][2:v]xfade=transition=circlecrop:duration=0.5:offset=31.674[tv1];[ta0][2:a]acrossfade=d=0.5[ta1];[tv1][3:v]xfade=transition=circlecrop:duration=0.5:offset=37.234[tv2];[ta1][3:a]acrossfade=d=0.5[ta2];[tv2][4:v]xfade=transition=circlecrop:duration=0.5:offset=55.348[tv3];[ta2][4:a]acrossfade=d=0.5[ta3];[tv3][5:v]xfade=transition=circlecrop:duration=0.5:offset=76.07[tv4];[ta3][5:a]acrossfade=d=0.5[ta4];[tv4][6:v]xfade=transition=circlecrop:duration=0.5:offset=82.622[tv5];[ta4][6:a]acrossfade=d=0.5[ta5];[tv5][7:v]xfade=transition=circlecrop:duration=0.5:offset=103.122[tv6];[ta5][7:a]acrossfade=d=0.5[ta6];[tv6][8:v]xfade=transition=circlecrop:duration=0.5:offset=114.502[tv7];[ta6][8:a]acrossfade=d=0.5[ta7];[tv7][9:v]xfade=transition=circlecrop:duration=0.5:offset=122.258[tv8];[ta7][9:a]acrossfade=d=0.5[ta8];[tv8][10:v]xfade=transition=circlecrop:duration=0.5:offset=130.094[tv9];[ta8][10:a]acrossfade=d=0.5[ta9];[tv9][11:v]xfade=transition=circlecrop:duration=0.5:offset=134.33[tv10];[ta9][11:a]acrossfade=d=0.5[ta10];[tv10][12:v]xfade=transition=circlecrop:duration=0.5:offset=141.85[tv11];[ta10][12:a]acrossfade=d=0.5[ta11];[tv11][13:v]xfade=transition=circlecrop:duration=0.5:offset=145.59[tv12];[ta11][13:a]acrossfade=d=0.5[ta12];[tv12][14:v]xfade=transition=circlecrop:duration=0.5:offset=154.314[tv13];[ta12][14:a]acrossfade=d=0.5[ta13];[tv13][15:v]xfade=transition=circlecrop:duration=0.5:offset=155.998[tv14];[ta13][15:a]acrossfade=d=0.5[ta14];[tv14][16:v]xfade=transition=circlecrop:duration=0.5:offset=164.924[tv15];[ta14][16:a]acrossfade=d=0.5[ta15];[tv15][17:v]xfade=transition=circlecrop:duration=0.5:offset=168.184[tv16];[ta15][17:a]acrossfade=d=0.5[ta16];[tv16][18:v]xfade=transition=circlecrop:duration=0.5:offset=174.796[tv17];[ta16][18:a]acrossfade=d=0.5[ta17];[tv17][19:v]xfade=transition=circlecrop:duration=0.5:offset=186.724[tv18];[ta17][19:a]acrossfade=d=0.5[ta18];[tv18][20:v]xfade=transition=circlecrop:duration=0.5:offset=191.23[tv19];[ta18][20:a]acrossfade=d=0.5[ta19];[tv19][21:v]xfade=transition=circlecrop:duration=0.5:offset=195.778[tv20];[ta19][21:a]acrossfade=d=0.5[ta20];[tv20][22:v]xfade=transition=circlecrop:duration=0.5:offset=198.118[tv21];[ta20][22:a]acrossfade=d=0.5[ta21];[tv21][23:v]xfade=transition=circlecrop:duration=0.5:offset=201.506[tv22];[ta21][23:a]acrossfade=d=0.5[ta22];[tv22][24:v]xfade=transition=circlecrop:duration=0.5:offset=204.422[tv23];[ta22][24:a]acrossfade=d=0.5[ta23];[tv23][25:v]xfade=transition=circlecrop:duration=0.5:offset=210.243[tv24];[ta23][25:a]acrossfade=d=0.5[ta24];[tv24][26:v]xfade=transition=circlecrop:duration=0.5:offset=215.417[tv25];[ta24][26:a]acrossfade=d=0.5[ta25];[tv25][27:v]xfade=transition=circlecrop:duration=0.5:offset=219.057[tv26];[ta25][27:a]acrossfade=d=0.5[ta26];[tv26][28:v]xfade=transition=circlecrop:duration=0.5:offset=221.277[tv27];[ta26][28:a]acrossfade=d=0.5[ta27];[tv27][29:v]xfade=transition=circlecrop:duration=0.5:offset=224.875[tv28];[ta27][29:a]acrossfade=d=0.5[ta28];[tv28][ta28][30:v][30:a][31:v][31:a][32:v][32:a][33:v][33:a][34:v][34:a][35:v][35:a][36:v][36:a][37:v][37:a][38:v][38:a][39:v][39:a][40:v][40:a][41:v][41:a][42:v][42:a][43:v][43:a][44:v][44:a][45:v][45:a][46:v][46:a][47:v][47:a][48:v][48:a][49:v][49:a]concat=n=21:v=1:a=1[v][a]" -map "[v]" -map "[a]" /tmp/export-clip-94989d271066ace00459-9ba57089-d833-4cef-beb7-3c847e9958af.mp4

  It stated that /tmp/0.mp4 has invalid data moov atom not found

  


  This only occurs when the number of clips > 20

  


  Additional info :

  


  

  • I can run without any error in my local environment using Windows 11 (FFMPEG version N-114902-g277f051ff6-20240421)

  


  • It fails on AWS Fargate environment using Ubuntu base image docker (FFMPEG version 7.1)

  


  


  I hope I can get a solutive answer based on my case at least I get what is wrong with my approach

  


• FFMpegCore.Exceptions.FFMpegException : 'ffmpeg exited with non-zero exit-code'

  15 octobre 2024, par secretply

  I am looking to retrieve the loudnorm data in JSON format from FFmpeg (using FFMpegCore 5.1.0). This is the code I currently have :

  


  await FFMpegArguments
    .FromPipeInput(new StreamPipeSource(fileStream.OpenReadStream()))
    .OutputToPipe(new StreamPipeSink(outputStream), options => options.WithCustomArgument("-af loudnorm=print_format=json"))
    .ProcessAsynchronously();


  


  This is the exception I get, which is similar to this old GitHub issue.

  


  System.IO.IOException: 'Pipe is broken.'

This exception was originally thrown at this call stack:
    System.IO.Pipes.PipeStream.PipeValueTaskSource.GetResult(short)
    System.IO.Pipes.PipeStream.PipeValueTaskSource.System.Threading.Tasks.Sources.IValueTaskSource.GetResult(short)

    FFMpegCore.FFMpegArgumentProcessor.Process(Instances.ProcessArguments, System.Threading.CancellationTokenSource)
    FFMpegCore.FFMpegArgumentProcessor.ProcessAsynchronously(bool, FFMpegCore.FFOptions)


  


  I am trying to replicate the following FFmpeg command and JSON output :

  


  ffmpeg -i "file.flac" -af loudnorm=print_format=json -f null -


  


  {
        "input_i" : "-21.87",
        "input_tp" : "-7.13",
        "input_lra" : "5.00",
        "input_thresh" : "-32.04",
        "output_i" : "-24.76",
        "output_tp" : "-10.36",
        "output_lra" : "4.10",
        "output_thresh" : "-34.84",
        "normalization_type" : "dynamic",
        "target_offset" : "0.76"
}


  


  If I add .ForceFormat("null") to the OutputToPipe options, I do not get the exception but when I read the output stream, it returns an empty string. In the issue mentioned, I know they mentioned a way to get the FFMpegErrorOutput property but I do not know how that can be done. I could not find an example of outputting a stream as JSON. If anyone can point me in the right direction or can provide an alternative solution, I would greatly appreciate it.

  


  Update

  


  I made a change to the StreamPipeSource() method where I copied over the uploaded file to a MemoryStream. With this change, the following FFMpegException is thrown.
