1176494 - Steam MSE DASH playback: video doesn't start

Status: RESOLVED FIXED

(Core :: Audio/Video, defect)

Description

[Jean-Yves Avenard [:jya]]

Using new MSE code, steam videos do not start.

for example:
http://steamcommunity.com/broadcast/watch/76561198047709840

you see the first frame being displayed and then it's stuck on "loading..."

Attachment: . P1. Ensure that progress event is fired upon successful appendBuffer.

Turned out that the steam DASH player expect the "progress" event to be fired and only then check if enough data has been buffered.
We weren't firing progress ever with the new MSE.
