I am creating a video hosting site where users can upload videos which are then converted into a web viewable webm format via FFMPEG, but I seem to have a problem getting the HTML5-video to work on Internet Explorer (IE 11, Windows 8.1, webm extensions installed).

The standard 'Big Bunny Buck' video (found here: http://www.webmfiles.org/demo-files/) works fine on IE, but if I convert a video to webm using FFMPEG it doesn't play at all but simply states 'Invalid Source' on the HTML5 video element.

I am using these commandline args to convert to webm on FFMPEG:

ffmpeg.exe -y -i bunny.webm -vcodec libvpx -acodec libvorbis -f webm bunny2.webm

Its werid as the videos work fine on VLC, windows media player, Firefox and Chrome but not on IE. Anyone ran into this issue before or could offer any pointers of how to fix it?

You can download this example zip (https://www.dropbox.com/s/dhp64c4rh7xqttj/IE-Webm.zip) which includes a bat script to run the above FFMPEG arguments and a html page for rendering two video elements for the before and after encoding with FFMPEG.

Thanks!

  • It's not a server issue as the example zip shows unfortunately. It seems to be a problem with the way FFMPEG encodes the video into the webm format. – Figroll Mar 20 '14 at 17:36
  • Did you copy the valid Big Buck movie to your server and played from there or did you only test on the source site? If you didn't copy the movie to test you could have a missing mime-type setting on the server. –  Mar 22 '14 at 18:53
  • The valid Big Buck movie works from the server. – Figroll Mar 24 '14 at 10:45
  • @rogerdpack libav seems to work! I guess I have to build my own FFMPEG with the latest libav? – Figroll Mar 24 '14 at 13:58
  • what libav are you using? what is the output of `ffmpeg -i movie_filename` for both the libav version and ffmpeg version [which might explain a difference]. Either way this feels like possibly a bug in ffmpeg...? – rogerdpack Mar 24 '14 at 16:38
  • Here are two info dumps from MediaInfo: http://pastebin.com/YmRQvDqs http://pastebin.com/tuWaf3QC Only difference seems to be the format version and writing application/library version – Figroll Mar 25 '14 at 10:35

Downloaded the latest version and seems to have sorted it, I must have just been really unlucky and grabbed a build that was broken!
