• ffmpeg convert from H.264 (High 4:2:2 Profile) MOV to H.264 (Baseline Profile) MP4

  26 juillet 2022, par froniq

  How can I convert a video (MOV) from H.264 (High 4:2:2 Profile) to H.264 (Baseline Profile) MP4 using ffmpeg ?
I would run that mp4 video on android mobile in a VideoView to support as many mobile types as possible.

  


  I can't do that with this command : ffmpeg -i o1.mov -c:v libx264 -profile:v baseline -c:a aac -ar 44100 -ac 2 -b:a 128k out.mp4.

  


  That'd return an error :

• Why is my ffmpeg not playing after converting it to .avi format

  26 mai 2017, par Jeeva

  I muxed the video and audio and then converted it to avi. The converted file has a size of 20mb but when i open it says cannot play the video. I tried playing it on a mobile also. Initially i tried converting it to mp4 but i was getting error like muxer does not support non seekable output Could not write header for output file Below is the code what i used. Can someone please tell me the mistake i’m doing.

  $video = "C:\Users\user.folder\Downloads\video_with_no_audio.mp4";
  
  $audio = "C:\Users\user.folder\Downloads\just_audio.mp3";
  
  $cmd = FCPATH.'ffmpeg/bin';
  
  $cmd1 = $cmd.'\ffmpeg -i '.$video.' -i '.$audio.' -y 2>&1 -f avi-';
  
  header('Content-type: video/avi');
  
  header("Content-Type: application/octet-stream");
  
  header("Content-Disposition: attachment; filename=file.avi");
  
  echo passthru($cmd1);exit;

  I Even tried with the following code

  $cmd1 = $cmd.'\ffmpeg -i '.$video.' -i '.$audio.' -c:v copy -c:a copy -y 2>&1 -f avi -';
