1175037 - Playback may stall following resolution change

Status: RESOLVED FIXED

(Core :: Audio/Video, defect)

Description

[Jean-Yves Avenard [:jya]]

I incorrectly interpreted the "active track" flag in the "Initialization Segment Received Algorithm" (http://w3c.github.io/media-source/index.html#sourcebuffer-init-segment-received)

It is reset to false once a new init segment is received and is only used to determine if the sourcebuffer should be added to the active list.

We rely on this flag to be true to tell the MediaFormatReader that new data has been received.

Without it playback will stall as the MediaFormatReader will never attempt to fetch new samples
