This and mozDownloadRate were available internally already for 'can play through' calculations so I just exposed what we already have. 'mozPlaybackRate' is a bad name though since there is already a concept of 'playback rate' for playback speed. > ?mozFrameCount - What do you propose a UA report for a partually downloaded VBR movie, or for a movie in a container that doesn't have a header (ie. one where you don't know the fame count until you have examined every byte in the file)? This is another bad name for what it actually is. It's a count of each frame as it is displayed. So the inverse of mozDroppedFrames really - it probably should be mozDisplayedFrames or something. I'm not sure if it's useful but it's the original stat I had for computing framerate playback in JavaScript in my tests. Chris. -- http://www.bluishcoder.co.nz
