• Converting avi to mp4 php fail

  27 octobre 2013, par Dirk Swarz

  I'm able to convert video via server command using:

  ffmpeg -i movie.avi -acodec libmp3lame -vcodec libx264 -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5 goodmovie.mp4
  

  For this test I used a 1.8mb video and after conversion it is 5 MB. I'm able to upload the video to my server after I download it from FTP and it will work with flash player, but when I try to automate this it fails.

  CODE:

  $ffmpeg_command = 'ffmpeg -i '.$new_name.' -acodec libmp3lame -vcodec libx264 -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5 '.$anew_name;
  $convert_avi = true;
  

  It converts to MP4, but

  • it is not 5 MB but rather 2.2 MB when the original file is 1.8 MB
  • it doesn't play in flash player.

  The main upload script is in upload.php which anyone can download from here:

  That code which i provided i just put into config.php

• Jwplayer function snapshot using ffmpeg and php

  27 octobre 2013, par Offboard

  before anything I'm using version 6, then the Snapshot plugin does not work.

  I'm finally with 2 questions, take a sequence of photos of a percentage of the video, so googled it and got this code from ffmpeg:

  ffmpeg -i video.mp4 -r 0.5 -f image2 output-%05d.jpeg
  

  so far so good, but I do not know how to take a screen shot of the video by setting the time, if I'm right this code is per frame.

  I searched again to get the function that calls the images, to generate good is quite simple, but the problem is that I found the pictures looks is all in one look.

  if anyone has any function or know how to do please tell me: D My English sucks, so do not call if I messed up.

  $convert_avi = true;

  -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5
  

  EDIT2: My ffmpeg info with installed libx264:

  Idea is when video is converted i can watch it via flash player and now flash player is saying that video is not found or bad syntax so obviuos its bad syntax but i dont know how to fix it
