title: Inconsistencies with HTML5 video in an Android WebView
body: <p>When showing an .mp4 video on an HTML5 page in an Android WebView, the video and audio are both played back properly when the file is retrieved from a remote URL.  When trying to play the same media file from within the device's "/mnt/sdcard/...." path, only the audio portion of the media file is played back.  Any thoughts on this ?  Has anyone experienced (and hopefully solved) anything similar?  Could this be a codec issue despite the fact that video is seen when retrieved over a network?  Is video returned over a network manipulated or transformed somehow before ending up in the WebView.</p>
