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.
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? ------------------ Original ------------------ From: "Lukáš Hrázký"<lhra...@redhat.com>; Date: Fri, Apr 13, 2018 07:24 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 Hello Delin, On Thu, 2018-04-12 at 10:37 +0800, 孙得霖 wrote: > hi, > I use spice for remote view, I want to captures the guest video output, > encodes it and send through, so I choose streaming agent, how to build and > run it is not clear, can you help me? Sure, first off, what exactly do you want to achieve? If you just want to remotely access your VM (see the graphical desktop and interact with it), you don't need the streaming agent for that, SPICE can do that for a long time without it. Streaming agent is designed for a very specific case of capturing and encoding the desktop from within the guest, which only has an advantage to the regular old SPICE approach if you have a physical GPU or a vGPU assigned to the guest to accelerate the process. If you still think streaming agent is what you need, please describe in detail what is your use case. > 1.host environment and Software version: > centOS(Mini install) > GVT-g kernel: https://github.com/intel/gvt-linux/ (branch: topic/dmabuf) > QEMU: https://github.com/intel/igvtg-qemu (branch: qa/dma_buf) > streming agent: https://gitlab.com/spice/spice-streaming-agent > spice-server version:0.13.3 > spice-protocol version:0.12.12 > > > 2.build info > kernel: > make -j 8 > make modules_install && make install > reboot > > > qemu: > ./configure --prefix=/usr --enable-kvm --disable-xen --enable-debug-info > --enable-debug --enable-sdl --enable-vhost-net --enable-spice > --disable-debug-tcg --enable-numa --enable-libusb --enable-curl > --enable-usb-redir --enable-linux-aio --target-list=x86_64-softmmu > --enable-gtk --with-gtkabi=3.0 > make -j 8 > cd roms/seabios > make -j 8 > cd - > make install > cp roms/seabios/out/bios.bin /usr/bin/bios.bin > > > spice-protocol: > ./configure --prefix=/usr > make -j 8 > make install > > > spice-service: > ./configure --prefix=/usr --enable-manual=no --disable-silent-rules > --disable-smartcard --disable-celt051 --enable-client CFLAGS="-g -O0" > CXXFLAGS="-g -O0" > make -j 8 > make install > > > streming agent > ./autogen.sh > make -j 8 > make install > > > 3.run qemu > /usr/bin/qemu-system-x86_64 \ > -m 8192 \ > -smp 4,sockets=1,cores=4,threads=1 \ > -M pc \ > -name win71 \ > -hda /Image/vm/win7_base.img \ > -bios /usr/bin/bios.bin -enable-kvm \ > -k en-us \ > -vga none \ > -display egl-headless \ > -spice disable-ticketing,port=6901,streaming-video=off \ > -machine kernel_irqchip=on,usb=on \ > -global PIIX4_PM.disable_s3=1 -global PIIX4_PM.disable_s4=1 \ > -cpu host -device usb-tablet \ > -device > vfio-pci,sysfsdev=/sys/bus/pci/devices/0000:00:02.0/5b8d581a-2dc9-11e8-8238-000906258002,x-display=on,x-igd-opregion=on > -device > virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel1,id=channel1,name=org.spice-space.stream.0 > -chardev spiceport,name=org.spice-space.stream.0,id=charchannel1 Are you running Windows 7 as the guest? The streaming agent is designed to run in the guest and only supports Linux atm.
