• FFMpeg giving me execution error

  I am trying to process a video file using php-ffmpeg, but I keep getting this error :

                      ->clip(FFMpeg\Coordinate\TimeCode::fromSeconds(0), FFMpeg\Coordinate\TimeCode::fromSeconds(MAX_VIDEO_PLAYTIME));
  
              }
  
  
  
              // Change the framerate to 16fps and GOP as 9.
  
              $video
  
                  ->filters()
  
                  ->framerate(new FFMpeg\Coordinate\FrameRate(16), 9);
  
  
  
              // Synchronize audio and video
  
              $video->filters()->synchronize();
  
  
  
              $video->save($format, $video_file_new_2);

  Please why am I getting this error and how do I solve it.

• ffmpeg concatenate results in bad/garbled output for second input file

  28 février 2017, par Dan

  I am trying to concatenate two videos together using the ffmpeg concat demuxer : a 5-second intro splash and a 60-second main/body video. I understand that the encoding needs to be the same on both files for this to work. I think they are, but the resulting output shows the intro just fine, followed by a totally garbled body. What am I missing ?

  ffmpeg -f concat -i concat.txt -c copy output.mp4

  Contents of concat.txt :

  file 'intro.mp4'
  
  file 'body.mp4'

  and the output of ffprobe for both input files :

  intro.mp4

  As far as I can tell, everything is identical except for the bitrate and language. Setting the language doesn’t seem to make a difference. I’ve tried to transcode the intro to a higher bitrate for the intro but can’t get it to stick in the output. I’m OK with transcoding one of the files (ideally the intro) but don’t know what else to try to change. Thoughts ?

• How to add text to video by time use ffmpeg

  15 mars 2017, par Thanh Dao

  I create my slideshow with command :
  

  "ffmpeg" -f concat -safe 0 -i /path/to/text.txt -i /path/to/audio.mp3 -vsync vfr -pix_fmt yuv420p /path/to/output.mp4

  The contents of text.txt

  file '/path/to/img1.jpg'
  
  duration 6
  
  file '/path/to/img2.jpg'
  
  duration 6
  
  file '/path/to/img3.jpg'
  
  duration 6
  
  file '/path/to/img4.jpg'
  
  duration 6
  
  file '/path/to/img5.jpg'
  
  duration 6
  
  file '/path/to/img6.jpg'
  
  duration 6

  The video has been cretaed perfectly. Now I want to add titles for each images displayed. Example :

  • img1.jpg displayed, show title Title 1
  • img2.jpg displayed, show title Title 2
  • img3.jpg displayed, show title Title 3

  I search a lot but got any solutions. Anyone help me. I’m stuck
