nit: I'm not sure why we seem to put parameters this way in IDL, but I think in
the cpp we usually follow more conventional chromium style.

This might be a good time to try out clang-format :-). You can run:
clang-format -i -style=Chromium ppapi/cpp/media_codec_video_decoder.*
to get just these files.
