ddorwin@: What did we decide on EME or Eme?

[ddorwin, 2014/03/06 18:11:10]

Eme (where we are addding new values). See line 65 for example.

But leave MSE alone for now to keep the changes to a minimum.

[jrummell, 2014/03/06 18:26:03]

Done.

[xhwang, 2014/03/06 16:36:53]

nit: We use UPPER_CASE for enums.

Suggestion for a follow up cleanup CL.

Now this is only used to test ParentThrowsException, which can easily be covered
by ECKEncryptedMediaTest. Then we can remove this test.

ddorwin/shadi: WDYT?

[ddorwin, 2014/03/06 18:11:10]

If Widevine is not registered (by line 334), this won't test the same path on
Win and Mac.
