• working ffmpeg command fails when using in nginx with rtmp module

  7 juin 2017, par Rafael Linux User

  I have a tested code I did in a "bash" file. It works perfect on shell. I change only params to get it to work with nginx rtmp module, but ffmpeg says always and understandable error. This is the code :

  exec_push ffmpeg -re -y -i rtmp://localhost:1935/live/$name  \
  
                              -c:v libx264 -c:a aac  \
  
                              -g 24 -keyint_min 24   -preset veryfast -tune zerolatency -movflags +faststart -vsync passthrough  \
  
                              -filter_complex '[0:v]format=pix_fmts=yuv420p,split=3[in1][in2][in3];[in1]scale=320:-2[320x];[in2]scale=640:-2[HQ640x];[in3]scale=1280:-2[HD1280x];[0:a]aresample=44100[audio]'  \

                              -map '[HQ640x]'     -profile:v baseline -level 3.1 -crf 25 -maxrate 1000k -bufsize 1000k    -f mp4 rtmp://localhost:1935/rtmp_hls/$name_HQ640x  \
  
                              -map '[HD1280x]'    -profile:v main -level 3.1 -crf 19 -maxrate 4000k -bufsize 4000k        -f mp4 rtmp://localhost:1935/rtmp_hls/$name_HD1280x  \
  
                              -map '[audio]'      -b 128k                                                                 -f mp4 rtmp://localhost:1935/rtmp_hls/$name_audio 2>>/var/www/html/ffmpeg-live-output-$name.log;

  And this is the error launched by mmpeg

• Using Node.js module fluent-ffmpeg to convert video but my files end up corrupt

  28 juin 2017, par El Guapo

  i am writing a node based media encoding tool and have found a few good node packages that will help me to do this, but the output files are either totally corrupt or it only encodes half the video.

  The main node package i am using is fluent-ffmpeg, and i am trying it with the following code :

  var ffmpeg = require('fluent-ffmpeg');
  
  
  
  var proc = new ffmpeg({ source: 'uploads/robocop-tlr1_h480p.mov', nolog: false})
  
    .withVideoCodec('libx264')
  
    .withVideoBitrate(800)
  
    .withAudioCodec('libvo_aacenc')
  
    .withAudioBitrate('128k')
  
    .withAudioChannels(2)
  
    .toFormat('mp4')
  
    .saveToFile('output/robocop.mp4',
  
      function(retcode, error){
  
          console.log('file has been converted succesfully');
  
  });

  There is not a problem with the source video as i encoded it just fine using FFmpeg normally with the following comand line string (i run it from a batch file) :

  "c:\ffmpeg\bin\ffmpeg.exe" -i %1 -acodec libvo_aacenc -b:a 128k -ac 2 -vcodec libx264 -b:v 800k -f mp4 "../output/robocop2.mp4"

  Any ideas what i am doing wrong here ?

• Videoshow NPM module with ffmpeg

  5 juillet 2018, par JZG

  I’m trying to use videoshow to convert multiple images to video, I have tried to change my code multiple times but now as you can see this is basically the same as in the module’s description page. Still I am receiving the following error as stated below.

  videoshow(images)
  
      .save('video.mp4')
  
      .on('start', function (command) {
  
          console.log('ffmpeg process started:', command)
  
      })
  
      .on('error', function (err) {
  
          console.error('Error:', err)
  
      })
  
      .on('end', function (output) {
  
          console.log('Video created in:', output)
  
      })
  
  
  
  
  
  Error: Error: ffmpeg exited with code 1: Error reinitializing filters!
  
  Failed to inject frame into filter network: Invalid argument
