Hi,
I have installed Ubuntu 10.10 32 bit on qemu image and I would like to use
-vga qxl option to start spice server from the command line. I think I
should check if qxl driver are installed in my ubuntu 10.10, how can I check
if they are already installed?
Thanks and sorry for my rusty english :)
Hi,
I have installed spice 0.8.0 and now I want to install the 0.8.1. I install
this package with:
./configure
make
sudo make install
When I run qemu, he runs with spice 0.8.0 and not with the new version.
Where is the error?
Thanks

Qemu starts only if I put spice server libraries in /usr/lib.

Hi
I am studying the source code and how spice handles streaming video. Spice
looks for area that are updated with high rate, after that it starts
mjpeg_encoder.
-I would like to know what are the SpiceAgent and the StreamClipItem, I see
these two elements in the source code.
-When spice detects v
h frame is
a jpeg image) with a spice protocol message.
Is it correct?
Thanks.

In order to measure compression time, you mean the time between
jpeg_start_compress() and jpeg_finish_compress, or the time of
encode_frame() function?

I would like to know what does these lines do. I have encoded a frame with
mjpeg, but how this frame is transmitted to the client?
Thanks.

Do you think that is possible to reduce further the compression time? If you
have an idea, I can try to implement it.
Thanks.

During my testing with video, I encountered this error on spice Server
"Application transferred too few scanlines"
and the server crashes.
Surfing on the net, I found this in jerror.h:
JMESSAGE(JERR_TOO_LITTLE_DATA, "Application transferred too few scanlines")
Bye.

Ok thanks.
I have another question. I want to try to separate the streaming data
and create a sperate channel for this kind of data. Do you think that
is better to work with the new client or with spicec?

Hi,
I want to try to implements a new channel dedicated to streaming
video. It's only an experiment, I don't know if this can bring an
improvement.
I would like to know some guidelines for implementing this channel. In

Hi,
On the client side spice handles stream data using multi media time. How is
calculated this multi media time??There is spice_session_get_mm_time() that
calculates this time but I don't understand how is calculated.
Each stream data have a member called multi_media_time, this member is

is TRUE, the video frame is dropped and then it will be not sent to the
client. Shortly, if a fra

I have a question about QXL and command ring. The QXL driver pushes the
commands into the command ring and Spice reads this commands from the ring
and process them.
Where can I find the code that pushes the commands into the command ring?

I've a simple question about update_area() function in Spice. I see there is
a QXLWorker interface, with a function called update_area. This function is

During my testing with streaming video, this function was never called, so
it is not used to update streaming video area. Ca

I know that on the Spice Client side I have a different thread (spicec) or a
