Thank you for the compliment. " https://www.linux-kvm.org/page/SPICE" is what I want. At first, I running Windows 7 as the guest, not clear how to use streaming agent. Next I will try CentOS as the guest.
now spice-server deal with stream like In the future, I want to send video stream to client direct, and decode in client side. Thank you so much for all the help that you had given me！ BR. ------------------ Original ------------------ From: "Lukáš Hrázký"<lhra...@redhat.com>; Date: Mon, Apr 16, 2018 04:20 PM To: "孙得霖"<kong.de...@embedway.com>; "spice-devel"<email@example.com>; Subject: Re: [Spice-devel] not clear how to use streaming agent On Mon, 2018-04-16 at 10:33 +0800, 孙得霖 wrote: > Hi, > Thanks for your response.it is first time to communicate in English,to be > frank, my English is not very good and there may be points expressed poorly > in my reply. 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 , there are some more information in . If you know you need more than regular SPICE can offer, please describe it.
