1131908 - [EME] GMPDecryptorChild should not send IPC messages after RecvDecryptingComplete() called

Status: RESOLVED FIXED

(Core :: Audio/Video, defect)

Description

[JW Wang [:jwwang] [:jw_wang]]

Call stack is like below:

GMPDecryptorChild::RecvDecryptingComplete
-> ClearKeySessionManager::DecryptingComplete
-> ClearKeySessionManager::Shutdown
-> ClearKeySession::~ClearKeySession
-> GMPDecryptorChild::KeyStatusChanged

GMPDecryptorChild::KeyStatusChanged() should not send IPC messages since RecvDecryptingComplete() will call Send__delete__() to delete GMPDecryptorParent. It is unstable to send IPC messages at the moment.
