Something that fits with conventions such as a light gray buffering progress bar could give the users an indication of the clip buffer. if the clip is paused because of buffering the outline of the progress bar could shift in a shade of gray and mouse over title could give a text description like: ".3x video download rate 3 min until ready for playback" In cases where the users is downloading slower than the bitrate of the video clip the user should get some indication (progress on a buffering bar) that the clip will soon be playable. The player should wait until enough of the clip has been download given the current download rate that it should be able to play though. ie what the html5 spec event is called: canplaythrough http://www.whatwg.org/specs/web-apps/current-work/#event-canplaythrough Reproducible: Always Steps to Reproduce: 1. Set your Bandwidth throttle to below the bitrate of the video clip 2. Attempt to play back the video clip Actual Results: Notice the video stops and Shutters without any user indication as to how long it will be paused the rate of buffering etc. Expected Results: The video should pause give the user some indication that its buffering and start playing once the canplaythrough event is fired.

"The player should wait until enough of the clip has been download given the current download rate that it should be able to play though. ie what the html5 spec event is called: canplaythrough" This is a separate issue to the buffering and is covered in bug 455654.

oky I adjusted the title and added refrence to that bug

Bug 462113 should cover the progress bar showing the buffered state.

I also filed bug 470983 for the specific case of stalled playback.
