• How to upload files to Azure Blob Stotage like FTP ?

  25 janvier 2016, par CG-Guy

  I am able to upload files from my ffmpeg app to an FTP using this path :

  ftp://[user:password]@server[:port]/MyFolder/video/video.flv

  How do I achieve the same thing in Azure Blob ? I have tried this path :

  https://[account-name].blob.core.windows.net/video/video.flv /DestKey:[account-storage-key]

  But that doesn’t seem to work. TCP connection shows the app is making a connection with the Azure account to the remote address 104.208.XXX.XX and remote port 443. However, it drops the connection and starts attempts to reconnect repeatedly. It will then time out after countless attempts and crash the app. I have also tried /> without success. The same thing happens. It attempts connecting to the remote address and port 80.

  The FFMPEG app has full access to firewall ports and the app communication shell show files are published without errors. System is a Server 2008 R2 unit on-site, not VM.

• "Error opening filters !" when using fluent-ffmpeg with Node

  3 février 2015, par doremi

  I’m trying to get a basic example of html5 video streaming working in an express node app, but I keep running into ffmpeg errors that I’m unsure of how to resolve.

  The input file/stream is the sample.mp4 located here.

  Complete example :

  var ffmpeg = require('fluent-ffmpeg');
  
  var express    = require('express');
  
  var fs         = require('fs');
  
  var sampleApp  = express();
  
  var videoApp   = express();
  
  
  
  var SAMPLE_SERVER_PORT = 3000;
  
  var VIDEO_SERVER_PORT  = 5000;
  
  
  
  sampleApp.get('/:video', function (req, res) {
  
    var videoURL = 'http://localhost:' + VIDEO_SERVER_PORT + '/' + req.params.video;
  
    return res.end('<video controls="controls" src=" + videoURL +"></video>');
  
  });
  
  
  
  videoApp.get('/:video', function(req, res) {
  
  
  
    res.statusCode = 200;
  
    res.setHeader('content-type','video/mp4');
  
  
  
    var stream = fs.createReadStream('./samples/' + req.params.video);
  
  
  
    var proc = ffmpeg(stream)
  
  
  
      .format('mp4')
  
      .size('320x?')
  
      .videoBitrate('512k')
  
      .videoCodec('libx264')
  
      .fps(24)
  
      .audioBitrate('96k')
  
      .audioCodec('aac')
  
      .audioFrequency(22050)
  
      .audioChannels(2)
  
  
  
      .on('error', function(err) {
  
        console.log('an error happened: ' + err.message);
  
      })
  
  
  
      .pipe(res, { end:true });
  
  });
  
  
  
  var server = sampleApp.listen(SAMPLE_SERVER_PORT, function () {
  
    console.log('Example app listening at http://%s:%s', server.address().address, SAMPLE_SERVER_PORT);
  
  });
  
  
  
  
  
  var videoServer = videoApp.listen(VIDEO_SERVER_PORT, function () {
  
    console.log('Video Server listening at http://%s:%s', server.address().address, VIDEO_SERVER_PORT);
  
  });

  The error (via console) :

  an error happened: ffmpeg exited with code 1: Error opening filters!

  ffmpeg configuration :

  ./configure  --prefix=/usr/local --enable-gpl --enable-nonfree --enable-libass \                                                                         
  
  --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus \
  
  --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --enable-libfaac --enable-libfdk-aac

  Any input would be greatly appreciated.

• avfilter/formats : Remove pointless checks

  11 septembre 2020, par Andreas Rheinhardt

  avfilter/formats : Remove pointless checks
  ff_formats_ref() takes a pointer to an AVFilterFormats and a pointer to
  
  a pointer to an AVFilterFormats as arguments and adds the latter as an
  
  owner to the list pointed to by the former ; the latter is hereby always
  
  the address of a list contained in an AVFilterFormatsConfig and can
  
  therefore not be NULL. So remove the check for whether it is NULL ; also
  
  do the same for ff_channel_layouts_ref().
  Also do the same for the unref functions where argument is never NULL
  
  because it is always the address of an existing lvalue.
