1176923 - Hit MOZ_CRASH(DOMEventTargetHelper not thread-safe) in TrackBuffersManager when appendMode == sequence

Status: RESOLVED FIXED

(Core :: Audio/Video, defect)

Description

[Jean-Yves Avenard [:jya]]

When appendMode is set to sequence, we need to set the timestampOffset.

This is done by calling SourceBuffer::SetTimestampOffset ; to do this we dispatch a task to the mainthread.
Creating the task calls AddRef on the SourceBuffer outside the main thread, which will assert.

Attachment: Don't add reference to SourceBuffer outside the main thread.
