1899646 - Netflix error 7353 for clearlead video

Status: RESOLVED FIXED

(Core :: Audio/Video, defect, P1)

Description

[Alastor Wu [:alwu]]

We received a report about rising error 7353 when watching clearlead video on Netflix, here is the profiled result. It seems that when recreating a MDSM, the newly created MDSM wasn't recovered to correct status. It was still trying to access data from 0s, but the video buffered range didn't contain that part of data anymore.

Attachment: Bug 1899646 - properly recover the status for a newly created state machine.

This reverts the change from D203062, which causes the newly created
MSDM not doing a proper recovery.

Attachment: Bug 1899646 - part2 : event 'loadmetadata' should only be dispatched once.

once.

According to the spec [1], the loadedmetadata should only be
dispatched once.

Depends on D212064
