* Those classes are not ready for public consumption. Ideally, I'd add a well designed BCodecRoster wrapping them. This is part of the general cleanup I am doing to get the code in a good state before going to finalize the design. * I don't plan to reintroduce BMediaFile in the media2 API, and I'd like to remove any (explicit) usage of entry_refs and things like that. * I plan to introduce BMetaData and BMediaFormat which is going to be different than what we do now. * We need to explicitly use the mime type when it's available and it is another design consideration when CodecRoster will be introduced.
