[FFmpeg-user] Problems with IE9

[Tim Gustafson]

Hi,

I've got a video service that's been up and running for a while that uses FFMPEG to convert all its videos.  It works very well, except in IE9 (of course).

Here's a link to the video player page:

I default to using HTML5 video (with MP4 and WEBM versions of each file), if available, and then fall back to a flash player if that doesn't work.  Here are the command lines that I use to create the MP4 video:

ffmpeg -y -i source.video -f mp4 -threads 4 -vcodec libx264 -vpre libx264-lossless_slow -b 768K -acodec libfaac -ar 22050 -r 30 -g 150 -s 800x600 ideo.mp4

It would appear that IE9 is attempting to use the MP4 video, but it chokes on it.  The player controls show up for a minute and then go away and don't come back, and even if you right-click the video and hit "play", it does not play.  Is there some better options that I should be choosing for MP4 video to work properly in IE9?
