1834101 - [wmfme] newly created state machine still can't handle seek (from previous state machine) properly

Status: RESOLVED FIXED

(Core :: Audio/Video: Playback, defect, P2)

Description

[Alastor Wu [:alwu]]

Bug 1833266 still didn't fix the Netflix issue for the media engine playback. Netflix works if the playback starts from the beginning, but it would fail if the playback starts from non-start. That means we still didn't handle seeking between two state machines properly.

Attachment: Bug 1834101 - part2 : discard seeking request from the old MDSM.

The old MDSM is going to be destroyed and it would reject the seeking
promise, which would result in aborting [1] the current seeking promise
for the media element.

Therefore, we should cancel that seeking request because we would
perform another new seek after recreating the MDSM, which would be the
one actually performing seeking.
