• hwcontext_vaapi : Try the first render node as the default DRM device

  hwcontext_vaapi : Try the first render node as the default DRM device
  If no string argument is supplied when av_hwdevice_ctx_create() is
  
  called to create a VAAPI device, we currently only try the default
  
  X11 display (that is, $DISPLAY) to find a device, and will therefore
  
  fail in the absence of an X server to connect to.  Change the logic
  
  to also look for a device via the first DRM render node (that is,
  
  "/dev/dri/renderD128"), which is probably the right thing to use in
  
  most simple configurations which only have one DRM device.

• How to render animated content in backend using nodejs ?

  29 novembre 2018, par user9964622

  I have created animation using tweenjs and createjs libraries createjs and tweenjs, now, I’d like to convert these animations to video files (MPEG4, or other, doesn’t matter) or how can I render it in the backend using nodejs ?

  I have animation looking like this : Animated

  Here is solution I have tried so far using nodejs and ffmpeg module

  var express = require('express');
  
  var cors = require('cors')
  
  var path = require('path');
  
  var app = express();
  
  var ffmpeg = require('ffmpeg');
  
  //Cors Middleware
  
  app.use(cors());
  
  // Body Parser Middleware
  
  app.use(bodyParser.json())
  
  // Port Number
  
  const port = process.env.PORT || 8000;
  
  //video processing
  
  
  
  try {
  
      var process = new ffmpeg('/path/to/your_movie.mp4');
  
      process.then(function (video) {
  
  
  
          video
  
          .setVideoSize('640x?', true, true, '#fff')
  
          .audioCodec('libmp3lame')
  
          .videoCodec('libx264')
  
          .setAudioCodec('libfaac')
  
          .setAudioChannels(2)
  
          .save('/path/to/save/your_movie.mp4', function (error, file) {
  
              if (!error)
  
                  console.log('Video file: ' + file);
  
          });
  
  
  
      }, function (err) {
  
          console.log('Error: ' + err);
  
      });
  
  } catch (e) {
  
      console.log(e.code);
  
  
  
  
  
  
  
  app.use('/video', video);
  
  app.get('/', (req, res) => {
  
    res.send('invaild endpoint');
  
  });
  
  
  
  app.get('*', (req, res) => {
  
    res.sendFile(path.join(__dirname + '/video-client/dist/video-client/index.html'));
  
  });
  
  
  
  // Start Server
  
  app.listen(port, () => {
  
    console.log('Server started on port '+port);
  
  });
