I hope you will pardon me for this. Your english is very good, don't worry (比我汉语更好 ;)). However, the information you provide is not what I asked, see below. > I want to capute guest video stream(encode it) and to client with spice protocol direct (like above figure ),at present, it is in the stage of technical pre-research. > So my question is, can i use streaming agent to capture guest video stream and encode it? That you want to capture the video and send it to the client is too vague and low-level. What do you want to use it for, the high-level use case? SPICE alone without the streaming agent can do what you are describing, you should probably start with that: Install SPICE from your distribution packages, follow a guide like [1], there are some more information in [2]. If you know you need more than regular SPICE can offer, please describe it.
