1176989 - New MSE doesn't handle changing encryption keys.

Status: RESOLVED FIXED

(Core :: Audio/Video, defect)

Description

[Jean-Yves Avenard [:jya]]

The MediaFormatReader handles EME keys during the ReadMetadata() ; however, with MSE multiple init segment may be found in the TrackBuffer.

We need to handle all keys for each init segment and fire the associated encrypted event.
