It seems like this must be do-able, but I can't see how.
For lots (most) streams on t'internet, you don't know how long it is until it's up and running, but you can figure it out pretty easily after that with a little javascript.
That's such a shame Elan! My football matches all have the wrong length. It feels weird watching Everton pound Chelsea into the ground with the wrong duration when I pause!
Oh well.
Actually, it probably doesn't even need to be configured does it? You could (very crudely) approximate it using seek bar length and elapsed time.
If I make a patch to do this (having not looked at the code at all yet...) would it be considered for inclusion, or is this something you're actively (deliberately) not doing right now.
There are a few things that need to be done for that timeline to display correctly, especially with seeking. We definitely have it on the list for the future, but it’s not trivial, unfortunately.
