The GStreamer, Cairo Video Hackfest Results
Last month we talked about a hackfest to improve Linux video playback that came about after a GNOME developer began work on using Cairo/Pixman for raw video in GStreamer and looking at other ways to leverage hardware acceleration within this major open-source multimedia framework. This Linux video meeting started in Barcelona on Thursday and is ending today, with some accomplishments.
Some of the code that has been (and continues to be) worked on is merging YUV support into Cairo/Pixman, a GLX Multi-thread extension, merging gst-plugins-cairo, XRenderPutImage/XV to Pixmap support, VA-API support for GStreamer, and getting the GStreamer Cairo plug-in to work on the Nokia N900. Another proposal that came about this week was a libgstva.so abstraction library that would allow video acceleration support in GStreamer across back-ends for VA-API, VDPAU, XvBA, and other video acceleration APIs.
