When adding Opus support, SPICE_INTERFACE_PLAYBACK_FREQ and SPICE_INTERFACE_RECORD_FREQ in the public header 'spice.h' were changed from 44100 to 48000. However, this was not really useful as these constants are not used in spice-server, but only by users of spice-server (ie QEMU). It turns out changing these values is actually harmful. QEMU uses these constants in 2 situations: 1. when it's a version of QEMU with this commit, but we are compiling against older spice-server headers (before Opus support was added) 2. when it's a version of QEMU without commit 795ca114d35 which added what is needed for Opus support When we are in the second situation, having 48000 in the public header will actually cause issues as spice-server will know QEMU does not support Opus, so internally spice-server will be using a 44100 rate for audio. However, QEMU will be using SPICE_INTERFACE_.*_FREQ and think it should use a 48000 rate, which will cause distorsions as experienced in bug https://bugzilla.redhat.com/show_bug.cgi?id=1129961 Reverting these constants back to 44100 will fix audio in the 'new spice-server/old QEMU' scenario, and won't cause issues either when both support Opus as in this case these constants are not used. |

SPICE: Simple Protocol for Independent Computing Environments
=============================================================
SPICE is a remote display system built for virtual environments which
allows you to view a computing 'desktop' environment not only on the
machine where it is running, but from anywhere on the Internet and
from a wide variety of machine architectures.
Installation
------------
The SPICE package uses GNU autotools, so the build install process
follows the standard process documented in the INSTALL file. As a
quick start you can do
./configure --prefix=/usr --sysconfdir=/etc \
--localstatedir=/var --libdir=/usr/lib
make
sudo make install
Or to install into a private user specific location
./configure --prefix=$HOME/spice
make
make install
The following mandatory dependancies are required in order to
build SPICE
Spice protocol >= 0.9.0
Pixman >= 0.17.7
OpenSSL
libjpeg
zlib
Cyrus-SASL
The following optional dependancies increase the available
functionality
GE Gui >= 0.6.0, < 0.7.0 (GUI app support)
OpenGL (GUI app support)
Alsa (Linux support)
XRandR >= 1.2 (X11 support)
Xinerama >= 1.0 (X11 support)
libcacard >= 0.1.2 (Smartcard support)
Communication
-------------
To communicate with the development team, or to post patches
there is a technical mailing list:
http://lists.freedesktop.org/mailman/listinfo/spice-devel
There is also a mailing list for new release announcements:
http://lists.freedesktop.org/archives/spice-announce/
To view known bugs, or report new bugs, in SPICE visit
https://bugs.freedesktop.org/describecomponents.cgi?product=Spice
Bugs found when using an OS distribution's binary packages should
be reported to the OS vendors' own bug tracker first.
The latest SPICE code can be found in GIT at:
http://cgit.freedesktop.org/spice/
