• AVC-Intra support

  20 juillet 2013, par Kieran Kunhya

  AVC-Intra support
  This format has been reverse engineered and x264’s output has almost exactly
  
  the same bitstream as Panasonic cameras and encoders produce. It therefore does
  
  not comply with SMPTE RP2027 since Panasonic themselves do not comply with
  
  their own specification. It has been tested in Avid, Premiere, Edius and
  
  Quantel.
  Parts of this patch were written by Jason Garrett-Glaser and some reverse
  
  engineering was done by Joseph Artsimovich.

• How to create a video from image buffers using fluent-ffmpeg ?

  23 juin 2016, par Zacky Pickholz

  I’ve been trying to create a slideshow from a series of images using nodejs + fluent-ffmpeg, however it is not working well or consistently. ffmpeg occasionally emits "Error : ffmpeg exited with code 1 : pipe:0 : Invalid data found when processing input", and in case an eventual video (mp4) is created it seems to be missing images/frames.

  The process is as follows : images are loaded into memory, transformed resized to same dimensions using lwip, written sequentially into a passthrough stream, which is fed to ffmpeg as input.

  Relevant code snippets :

  var lwip = require('lwip');
  
  var ffmpeg = require('fluent-ffmpeg');
  
  var stream = require('stream');
  
  var imagesStream = new stream.PassThrough();
  
  
  
  ...
  
  
  
  image.batch()
  
              .contain(options.video.width, options.video.height, 'lanczos')
  
              .toBuffer(options.frames.format, {quality: 100}, (err, buffer) => {
  
                  if (err) {
  
                      throw ('error convering image to buffer. ' + err);
  
                  }
  
                  imagesStream.write(buffer, 'utf8');
  
                  resolve();
  
              });
  
  
  
  ...
  
  
  
      ffmpeg(imagesStream)
  
          .inputOptions('-framerate 1/' + options.frames.secsPerImage)
  
          .input(path.join(AUDIO_ROOT, options.audio.track))
  
          .save(path.join(path.join(OUTPUT_FOLDER, `${options.video.output.prefix}${timestamp}.${options.video.output.format}`)))
  
          .size(`${options.video.width}x${options.video.height}`)
  
          .on('start', () => {
  
              console.log('creating the clip now...')
  
          })
  
          .on('progress', (progress) => {
  
              var progPercent = Math.round(100 * progress.frames / (numImages * options.frames.secsPerImage * 25));
  
              progPercent = Math.min(progPercent, 100);
  
              console.log(`processing: ${progPercent}% done`)
  
          })
  
          .on('stderr', (line) => {
  
              console.error('ffmpeg error: ' + line);
  
          })
  
          .on('error', (error) => {
  
              reject('ffmpeg transcoding error: ' + error);
  
          })
  
          .on('end', () => {
  
              console.log('done!');
  
              resolve(true);
  
          })
  
          .run();

  And here is the output :
