• Concatenate audio with image and video using ffmpeg

  9 May 2018, by huynq9

  I have 1 image, 1 audio file and 1 video. I would like to merge all of them to make a video which will

  • show the image and play audio file for the first 10s
  • play the video file

  here is what I was trying to do so far.

  ffmpeg \
  
  -loop 1 -framerate 24 -t 10 -i item1.jpg \
  
  -i "https://audio-ssl.itunes.apple.com/apple-assets-us-std-000001/Music/66/58/f7/mzi.eoocfriy.aac.p.m4a" \
  
  -i item4.mp4 \
  
  -filter_complex \
  
  "[0]scale=432:432,setdar=1[img1]; \
  
   [1]volume=1[aud1]; \
  
   [2]scale=432:432,setdar=1[vid1]; \ 
  
   [img1][aud1][vid1] concat=n=3:v=1:a=1" \
  
  outputfile.mp4

  I got the error:

  [Parsed_setdar_4 @ 0x3063780] Media type mismatch between the
  ’Parsed_setdar_4’ filter output pad 0 (video) and the
  ’Parsed_concat_6’ filter input pad 1 (audio) [AVFilterGraph @
  0x30479a0] Cannot create the link setdar:0 -> concat:1 Error
  initializing complex filters. Invalid argument

  I tried to googled but still cannot figure out what I am doing wrong?

  Updated:
  I ran the following command:

  ffmpeg \
  
  -loop 1 -framerate 24 -t 10 -i item1.jpg \
  
  -t 10 -i "https://audio-ssl.itunes.apple.com/apple-assets-us-std-000001/Music/66/58/f7/mzi.eoocfriy.aac.p.m4a" \
  
  -i item4.mp4 \
  
  -f lavfi -t 1 -i anullsrc \
  
  -filter_complex \
  
  "[0]scale=432:432,setsar=1[img1]; \
  
  [2]scale=432:432,setsar=1[vid1]; \ 
  
  [img1][1][vid1][3] concat=n=2:v=1:a=1" \
  
  outputfile.mp4

  and got the following error:

• ffmpeg converting MOV to MP4 add 5 second still frames to start of video [closed]

  17 February 2013, by Webfox

  I have a website that automatically converts MOV files to MP4. For some reason the client videos (which are exported from their own software) have about 5-8 seconds worth of a still frame added to the beginning of each video when they are converted. I have tried so many different variations trying to sort this but its always the same.

  The function/ffmpeg command that is currently being used is

      public function convertToMP4($file, $destination, $size=null, $qscale='10', $rate=25, $ab='192k', $ar=44100) {
  
      if (substr($destination, -1) == '/') {
  
          $destination = substr($destination, 0, -1);
  
      }
  
  
  
      $filename = end(explode("/", $file));
  
      $outfile = current(explode(".", $filename)).".mp4";
  
  
  
      // Media Size
  
      if (!isset($size) || $size == 'copy') {
  
          if ($dims = $this->getDimensions($file)) {
  
              $size = $dims['width'].'x'.$dims['height'];
  
          }
  
      }
  
      if ($ab == false) {
  
          $cmd = "ffmpeg -i $file -qscale $qscale -an -f mp4 -s $size -aspect 16:9 $destination/$outfile";
  
      } else {
  
          $cmd = "ffmpeg -i $file -acodec ".$this->mp3lib." -qscale $qscale -r $rate -ar $ar -ab $ab -f mp4 -s $size -aspect 16:9 $destination/$outfile";
  
      }
  
  
  
      $ret = shell_exec($cmd);
  
  
  
      if (file_exists("$destination/$outfile")) {
  
          return "$destination/$outfile";
  
      }
  
      return false;
  
  }

  where if $ab is false then remove the sound which is the case for 99% of the videos in scenario

  Thanks

• FFMPEG video encoded by android app doesn't scale properly on the website

  9 October 2016, by Ahmed Mujtaba

  I’m trying to creat e an app that records a video on phone and uploads it to the website. I’m using a FFMPEG library to encode the video to be streamed on the web. The command I’m using for encoding is below:

  -y i inputPath -vf scale=640:480,transpose=1 -strict experimental -s 360x640 -r 25 -vcodec mpeg4 -b 1000k ab 48000 -ac 2 -ar 22050 destinationPath

  The video is encoded fine but when I try to play it on the website, it’s stretched vertically and goes off the screen. I’m using html5 player to play it on the web. Here’s what the video looks like

  

  The video uploaded from the website is encoded using libx264 codec and it plays fine. However the library I’m using to encode on the android app doesn’t support libx264. I’m not sure if it’s the incorrect aspect ratio that’s messing up the playback or something else. I’ve set the aspet ratio to 640:480 but that hasn’t fixed things.
  Can anyone help?
