"encrypted_media" seems like a very specific name. I would have expected it to
be "media", though I see many other components are specific.

Is this really handling "encrypted media" or is it just "cdm"?

cdm sgtm. we already have src/media/cdm folder.

Thanks for suggesting good component name.
The only concern is that the namespace is conflicted with
content_decryption_module.h in ppapi:
https://code.google.com/p/chromium/codesearch#chromium/src/media/cdm/ppapi/ap...

Do you think it's OK to use the same namespace or any other suggestion on the
namespace?
