• ffmpeg using exec() output must be realtime

  5 janvier 2015, par gadss

  Hi I am suing windows and linux OS and I am using php for uploading videos, using ffmpeg I can convert videos to other file type. in commandline I can convert and thru php code, but I have problem in displaying the output executed data in my php, it cannot be done in echo this is my code. :

  $webm = 'ffmpeg -i c:\xampp\htdocs\vidcon\video.mp4 -acodec libvorbis -aq 5 -ac 2 -qmax 25 -threads 2 c:\xampp\htdocs\vidcon\new\myvideo.webm';
  
      echo exec ($webm); 

  but when I run it, it doesn’t have any display.. what I want to display is like this... something like a progress in converting the video displaying in php...

• mp4 not playing in Firefox 35 on Mac, wrong MIME type ?

  5 février 2015, par Andy

  I got two mp4-Videos, both with the same codes (h264 for video and aac for audio), which are returning different mime types on linux :

  $ file --mime-type one.mp4
  
  one.mp4: video/mp4
  
  
  
  $ file --mime-type two.mp4
  
  two.mp4: video/qicktime

  two.mp4 wont play in Firefox 35 on a certain Windows installation and a Mac OS X 10.10 installation, while one.mp4 does.

  I compared the videos with ffmpeg, and the Video-Stream lines are :

  one.mp4 :

  Stream #0:0(und) : Video : h264 (Constrained Baseline) (avc1 / 0x31637661), yuv420p, 640x640 [SAR 1:1 DAR 1:1], 735 kb/s, 29.97 fps, 29.97 tbr, 11988 tbn, 59.94 tbc (default)

  Metadata:
  
    handler_name    : VideoHandler

  two.mp4 :

  Stream #0:1(eng) : Video : h264 (Baseline) (avc1 / 0x31637661), yuv420p(tv), 1024x576 [SAR 1:1 DAR 16:9], 1002 kb/s, 25 fps, 25 tbr, 600 tbn, 50 tbc (default)

  Metadata:
  
    creation_time   : 2015-01-23 14:16:08
  
    handler_name    : Apple Alias Data Handler
  
    encoder         : MainConcept H.264

  Can this be a reason for the difference in MIME-Type ?
  And what could I do to change that ?

  Merci beaucoup.

  configure : Only redefine inline to __inline for msvc if necessary
  This isn’t necessary on MSVC 2015 any longer.
