Once it is determined that an Intel GPU is available/active (after looking into udev's database), we try to see if there is a h/w based encoder (element) available (in Gstreamer's registry cache) for the user selected video codec. In other words, if we find that the Intel Media SDK Gstreamer plugin (libgstmsdk.so) and associated libraries (such as va or vaapi) are all installed properly, we add the appropriate h/w based encoder and post-processor/converter elements to the pipeline (along with any relevant options) instead of the s/w based elements. For example, if the user selects h264 as the preferred codec format, msdkh264enc and vapostproc will be preferred instead of x264enc and videoconvert. v2: (addressed some review comments from Frediano) - Moved the udev helper into spice-common - Refactored the code to choose plugins in order msdk > va > vaapi v3: (Frediano) - Added relevant encoder options for mjpeg and vp9 codecs (Jin Chung) v4: (Fixups from Frediano) - Free the encoder when we cannot find vpp - Change type and find plugins array length using G_N_ELEMENTS - Fix gstenc_name UAF by freeing it at the end of the function - Use g_str_has_prefix instead of strstr - Include the string "_hw_" in function names that deal with h/w based plugins - Rebase on master v5: rebase on master Cc: Frediano Ziglio <freddy77@gmail.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: Marc-André Lureau <marcandre.lureau@redhat.com> Cc: Dongwon Kim <dongwon.kim@intel.com> Signed-off-by: Vivek Kasireddy <vivek.kasireddy@intel.com> Co-developed-by: Jin Chung Teng <jin.chung.teng@intel.com> Co-developed-by: Hazwan Arif Mazlan <hazwan.arif.mazlan@intel.com> |

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 dependencies are required in order to
build SPICE
Spice protocol >= 0.14.0
Pixman >= 0.17.7
OpenSSL
libjpeg
zlib
The following optional dependencies increase the available
functionality
Cyrus-SASL
libcacard >= 2.5.1 (Smartcard support)
Opus >= 1.0.0 (Opus audio encoding support)
LZ4 (LZ4 compression support)
GStreamer >= 1.0.0
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://gitlab.freedesktop.org/spice/spice/issues/new?
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:
https://gitlab.freedesktop.org/spice/

License as published by the Free Software Foundation; either
version 2.1 of the License, or (at your option) any later version.
