[Spice-devel] [RFC v3] Allow guest-video codec hot-swap

[Kevin Pouget]

This is a new version of the patch series on guest video codec hot
swapping.

A few TODO remain open/to be discussed, in particular:

- in the client, what is the proper way to fix the visible area issue
- allowing the host admin to control which codec can be used for guest
  streaming
- in the server, on codec change, reset only the streams of the client
  that requested the change
