Description Yonit Halperin 2012-04-18 14:41:23 UTC
Description of problem:
Windows7 guest
Played html5 youtube on Firefox 10.0.1
The movie frames are not classified by spice as video, i.e., they are not mjpeg compressed. The playback is bad as the connection is more limited.

The cause:
spice-server classifies as video streams only drawing commands that their destination surface is the primary one. However, the html5 playback is drawn onto an offscreen surface and is then copied to the primary surface.
We can extend spice to support off-screen surfaces streams, but in order to do that we need to change the inter-surface dependency logic in spice-server.

the fix is not up-stream yet, and as the result - out of time for 6.4 -> moving to 6.5

I am testing RHEV-M si20 with a RHEL 6.3 host and a Windows 7x86_64 guest. I added the 3.1-7 tools ISO and upgraded the QXL driver to qxl-win-0.1-17 (Signed driver from WHQL).

I am seeing glitching with the HTML5 stream in IE9. The jumps are relatively small but very frequent.

I am also seeing the issue of HTML5 strem skipping, in full screen the quality is very bad on a Win 7 32bit guest.

*Testing qxl-win-0.1.17 (updated from the 3.1.7 tools ISO) on RHEVM si20 with a Win 7 32 bit guest & RHEL 6.3 host.

Comment 7 RHEL Program Management 2013-10-14 05:02:31 UTC
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

I am not sure why this bug was created instead of updating https://bugzilla.redhat.com/show_bug.cgi?id=809208.

I am installing some RHEV-M instances this week and will retest.

Comment 11 David Blechter 2014-06-09 17:22:36 UTC
low priority, but keep it for 6.6 for now

Comment 12 Marc-Andre Lureau 2014-06-18 18:32:43 UTC
it is correctly streamed as video with rhevm 3.4, both with win7 and rhel6 guests, using firefox html5. closing for now
