MP4 url plays audio but no video in Chrome browser on Android 4.1.2

[Chris Austin]

Hi, I?m trying to play a url to an .mp4 file within a Chrome browser on Android 4.1.2.

When I click the link I get the playback progress bar and when I click play I get audio but no video within the browser. When I click play fullscreen however the video plays fine filling the screen.

Here is an example link which gives the issues above ?  http://download.wavetlan.com/SVV/Me..._Media/H264_test1_Talkinghead_mp4_480x360.mp4

Any help with this issue would be greatly appreciated.

Thanks

Chris
