Could you please provide more context about what "media remoting feature" is?

Sure, the media remoting is the original project we discussed.
Instead of using mojo::renderer and mojo:cdm, we decide to create its own mojo
service, its own renderer and its own media keys implementation, to covert
message to RPC using proto buffer in the render process, and send the byte array
to browser process.

With such solution, we can eliminate security concern on parsing data in browser
process.
