1129720 - [EME] IPDL errors when using MSE decoder-per-segment

Status: RESOLVED DUPLICATE of bug 1130932

(Core :: Audio/Video, defect)

Description

[Chris Pearce [:cpearce (Not reading bugmail)]]

If you set media.mediasource.decoder-per-segment=true, MSE will instantiate a new decoder for every append made to a source buffer. This simulates a lot of little seeks.

If we load http://people.mozilla.org/~cpearce/mse-clearkey/ with that pref set, on tab close we see lots of IPDL errors:

[7616] WARNING: Trying to use a dead GMP decrypter!: file c:\Users\cpearce\src\mozilla\purple\dom\media\gmp\GMPDecryptorParent.cpp, line 273
IPDL protocol error: Handler for KeyStatusChanged returned error code

###!!! [Parent][DispatchAsyncMessage] Error: (msgtype=0x520014,name=PGMPDecryptor::Msg_KeyStatusChanged) Processing error: message was deserialized, but the handler returned false (indicating failure)

We should figure out what these errors are, and fix them.

Fallout from the ClearKey refactor/WMF changes, I'm fairly sure. Not fatal, afaict.

It looks like the symptom described in bug 1130932.

Mass update firefox-status to track EME uplift.
