Media Controls Timeline is not updated when appending 3 seconds segment in the middle of a MSE video |
||
Issue descriptionChrome Version : 62.0.3176.0 OS Version: 9840.0.0 What steps will reproduce the problem? 1. Go to https://beaufortfrancois.github.io/samples/media/live-seekable-range.html 2. Click "fetch & append 3 to 6 seconds media segment" button What is the expected result? The video timeline should show 3 seconds of buffered video. What happens instead of that? Nothing.

I wish this would work as it would be great to know which parts of the video user can watch when offline for instance.

Maybe the native controls need to know whether or not there is a 'live seekable range' currently set on the mediasource attached to the element. Three overall cases here, when duration is +Infinity; for each, what should the video timeline show (if anything) if there is a) something buffered, or b) nothing buffered? 1) not MSE, just SRC 2) MSE, but no live seekable range is currently set 3) MSE, with a live seekable range currently set I suspect there's likely a desire to differentiate at least (2) vs (3).

FYI, the official sample is now available at https://googlechrome.github.io/samples/media/live-seekable-range.html
