This patch implements support in LibVNCClient for framebuffer updates encoded as H.264 frames. Hardware accelerated decoding is performed using VA API. This is experimental support to let the community explore the possibilities offered by the potential bandwidth and latency reductions that H.264 encoding allows. This may be particularly useful for use cases such as online gaming, hosted desktops, hosted set top boxes... This patch only provides the client side support and is meant to be used with corresponding server-side support, as provided by an upcoming patch for qemu ui/vnc module (to view the display of a virtual machine executing under QEMU). With this H.264-based encoding, if multiple framebuffer update messages are generated for a single server framebuffer modification, the H.264 frame data is sent only with the first update message. Subsequent update framebuffer messages will contain only the coordinates and size of the additional updated regions. Instructions/Requirements: * The patch should be applied on top of the previous patch I submitted with minor enhancements to the gtkvncviewer application: http://sourceforge.net/mailarchive/message.php?msg_id=30323804 * Currently only works with libva 1.0: use branch "v1.0-branch" for libva and intel-driver. Those can be built as follows: cd libva git checkout v1.0-branch ./autogen.sh make sudo make install cd .. git clone git://anongit.freedesktop.org/vaapi/intel-driver cd intel-driver git checkout v1.0-branch ./autogen.sh make sudo make install Signed-off-by: David Verbeiren <david.verbeiren@intel.com> |
