• Running frei0r filters with ffmpeg - "Could not find module 'pixeliz0r'."

  4 avril 2016, par ksloan

  I installed frei0r using homebrew

  MacK:tmp kevin$ brew list frei0r
  
  /usr/local/Cellar/frei0r/1.4/include/frei0r.h
  
  /usr/local/Cellar/frei0r/1.4/lib/frei0r-1/ (119 files)
  
  /usr/local/Cellar/frei0r/1.4/lib/pkgconfig/frei0r.pc
  
  /usr/local/Cellar/frei0r/1.4/share/doc/ (4 files)

  Then I installed ffmpeg with the --with-frei0r flag, and everything compiled fine

  brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-libass --with-libquvi --with-libvorbis --with-libvpx --with-opus --with-x265 --with-frei0r

  I tried telling ffmpeg where my frie0r filters were installed with

  export FREI0R_PATH=/usr/local/Cellar/frei0r/1.4/lib/frei0r-1/

  I even created symlinks from the default locations ffmpeg checks...

  MacK:tmp kevin$ ls -l  /usr/local/lib/frei0r-1
  
  lrwxr-xr-x  1 kevin  admin  33  4 Apr 04:43 /usr/local/lib/frei0r-1 -> ../Cellar/frei0r/1.4/lib/frei0r-1

  But I’m still seeing this error :

  [Parsed_frei0r_0 @ 0x7f8938f003c0] Could not find module 'perspective'.
  
  [AVFilterGraph @ 0x7f8938f00160] Error initializing filter 'frei0r' with args 'perspective'
  
  Error initializing complex filters.
  
  Invalid argument

  Full output :

• ffmpeg compilation error in windows 10 x64 for Visual Studio 2015 CE

  12 avril 2016, par Anqush

  So i was trying to use FFmpegInterop for win10 UWP application. And followed the specification given on https://trac.ffmpeg.org/wiki/CompilationGuide/WinRT.

  here is some environment information :

  VS2015 Community Edition with 10.0.10240.0 SDK

  OS : Windows 10 Enterprise x64

  PATH were set to:Program Files (x86)/Microsoft Visual Studio 14.0/VC/BIN/x64_ARM

  So when i did this in msys2_shell.bat

  ../../../configure \
  
  --toolchain=msvc \
  
  --disable-programs \
  
  --disable-d3d11va \
  
  --disable-dxva2 \
  
  --arch=x86_64 \
  
  --enable-shared \
  
  --enable-cross-compile \
  
  --target-os=win32 \
  
  --extra-cflags="-MD -DWINAPI_FAMILY=WINAPI_FAMILY_APP -D_WIN32_WINNT=0x0A00" \
  
  --extra-ldflags="-APPCONTAINER WindowsApp.lib" \
  
  --prefix=../../../Build/Windows10/x64

  I got a warning regarding some pkg file that can’t be found and may cause library detection issues.

  For then i ignored it. After that i entered

  make

  this started a series of processing in which there is a lot of possibly harmful warnings. Like :-

  c:\ffmpeginterop\ffmpeg\libavcodec\get_bits.h(307): warning C4101: 're_cache': unreferenced local variable
  
  CC libavformat/srtdec.o
  
  srtdec.c
  
  c:\ffmpeginterop\ffmpeg\libavutil\libm.h(438): warning C4211: nonstandard extension used: redefined extern to static
  
  c:\ffmpeginterop\ffmpeg\libavformat\subtitles.h(189): warning C4267: 'initializing': conversion from 'size_t' to 'int', possible loss of data

  So my question is that. Is this dangerous to proceed with. Can you help me for i should proceed with my project without any worry or not ? And i would be gratefull if anyone can guide me to watc out for specific errors that this could generate.

  I know this is a lot to ask. But i would be gratefull.
  Thanks

  Edit : Now i cant run the samples included in the ffmpeginterop package. The sample project wont debug. saying these are out of date.

• videoshow npm module not working fine

  14 avril 2016, par Anshul

  I have used videoshow NPM module for creating a video using images but it is not working fine for me it is running twice or thrice and creating multiple videos for same images sometimes. If i am changing the value of loop in the code to ’1’ it is running fine but the slide duration is only one second.

  Here is my code :-

  var images = [
  
      'public/images/1.png',
  
      'public/images/2.png',
  
      'public/images/3.png',
  
      'public/images/4.png',
  
      'public/images/5.png',
  
      'public/images/6.png',
  
      'public/images/7.png',
  
      'public/images/8.png',
  
      'public/images/9.png'
  
  ]
  
  
  
  var videoOptions = {
  
      fps: 25,
  
      loop: 3, // seconds
  
      transition: true,
  
      transitionDuration: 1, // seconds
  
      videoBitrate: 1024,
  
      videoCodec: 'libx264',
  
      size: '640x480',
  
      audioBitrate: '128k',
  
      audioChannels: 2,
  
      format: 'mp4'
  
  }
  
  
  
  var videoPath = 'public/video/test.mp4';
  
  
  
  videoshow(images, videoOptions)
  
  .audio('public/audio/1.mp3')
  
  .save(videoPath)
  
  .on('start', function (command) {
  
      console.log('ffmpeg process started:', command)
  
  })
  
  .on('error', function (err, stdout, stderr) {
  
      res.send({status : false, message: 'Something went wrong. Please try again.'});
  
      res.end();
  
      return;
  
  })
  
  .on('end', function (output) {
  
      res.send({status : true, message: ''});
  
      res.end();
  
      return;
  
  });
