• Rotate video adding black bars with ffmpeg

  13 février 2016, par MrMoog

  I have a lot of mp4 full hd videos made with a smartphone that looks rotated 90°.

  These files have proper rotation metadata and they plays correctly on VLC or other desktop mediaplayers, but I want to display them on my dvd player that does not handles mp4 metadata.

  So I tried to transpose with ffmpeg but I obtain 1080x1920 files, resolution obviously not recognized by tv/dvd-player.

  How can I transpose, resize and add black side (left/right) bars of the correct dimensions to get "correct" 1920x1080 videos ?

• ffmpeg generate first non black frame

  17 octobre 2019, par Milousel

  I get via readstream video from AWS server. I modify it into different format and save it back into server. After that I want to create non black image from first frame of this video. So I need to check if first frame is black or not.

  ffmpeg(stream)
  
          .size('1320x438')
  
          .videoCodec('libx264')
  
          .toFormat('avi')
  
          .output(fileName)
  
          .on('end', function() {
  
            console.log('Finished processing video');
  
            const params = {
  
              Body: fs.createReadStream(fileName),
  
              Bucket: videoBucket,
  
              Key: 'test/modification/' + fileName,
  
            };
  
            s3.putObject(params, (err, data) => {
  
              if (err) {
  
                console.log(err);
  
              }
  
            });
  
          })
  
          .output(screensName + '.jpg')
  
          .outputOptions(
  
            '-frames',
  
            '1', // Capture just one frame of the video
  
          )
  
          .on('end', function() {
  
            console.log('Finished processing screenshot');
  
            const params = {
  
              Body: fs.createReadStream(screensName + '.jpg'),
  
              Bucket: videoBucket,
  
              Key: 'test/shots/' + screensName + '.jpg',
  
            };
  
            s3.putObject(params, (err, data) => {
  
              if (err) {
  
                console.log(err);
  
              }
  
            });
  
          })
  
          .run();
