This filename is not super meaningful in media/crypto/. Maybe it should mention
[W]MP or something.

Changed to encrypted_media_player_support based on offline discussion.

Is the intent that Android will have its own?

[acolwell GONE FROM CHROMIUM, 2014/08/22 23:20:22]

No, but this code doesn't build under Android because of the "#error Browser
side CDM in WMPI for prefixed EME API not supported yet." in the code. I took
quick look at WMPA and it looks like most of the code is the same so it could
probably use most of the code in here eventually.

Won't you need to address WMPA before moving code to media/blink? Is that the
next step?

[acolwell GONE FROM CHROMIUM, 2014/08/25 18:10:43]

I don't plan on moving WMPA to media/blink yet and I don't believe I'll need to
resolve this before. We'll see when I get my WMPI move patch uploaded and sent
to the try bots.
