I have uploaded two mp4 video files to windows live skydrive. When I browse to them in firefox (10.0) the lower res one plays perfectly but the higher res plays only audio the video remains blank.

this file plays video and audio correctly  :

   File name
   P1000505_x264
   Dimensions
   480 x 320
   Duration
   0:43
   Bitrate
   774 Kbps
   Size
   4,565 KB
   Type
   MP4 File

this higher resolution file plays audio but no video :

   File name
   P1000805_x264
   Dimensions
   960 x 640

Is it possible for you to post links to these videos?

Also, if you update to Firefox 12, does that help?

Firefox doesn't play H.264 encoded mp4 files natively, so you need a player that can handle them.

Which code do you use to play those videos?

I am not doing anything special. The videos should play within the browser. I log into my skdrive account browse my uploaded photos and videos and click. In IE both files play correctly but in FF ( including V12.0) the higher res mp4 does not show video. Both play in VLC. I have read that H.264 is not supported in FF so why does one play?

Any ideas anyone? This happens on 2 different PC's I have. Niether Firefoxs have any plugins for quicktime and quicktime is not installed on the PCs. Can anyone confirm they have the same situation if they try play videos in firefox?

Are Forums any good? - whenever I post I always end up having to answer my own question eventually! - aaah well, anyway for the benefit of anyone interested I suspect it is flash player in firefox browser that is playing the MP4's and perhaps it cannot cope with the higher resolution format.
