Release notes for GStreamer 0.10.26 "Think Twice"

Features of this release

• Threadsafe design and API
• registry: do plugin scanning (on *nix) using an external helper binary
• lots of performance improvements all over the place (ghostpads, multiqueue, pad construction, superfluous type checks, registry loading)
• add GstByteWriter, a simple generic byte writer
• filesink: Use _wfopen on win32 to open files with non-ascii filenames correctly.
• queue2: add option to remove the temp-file (enabled by default)
• it is now allowed to use gst_caps_set_simple() on non-simple caps
• queue2: move from gst-plugins-base into the coreelements plugin in core (this means you may need to remove libgstqueue2.so manually if you installed from source and don't do make uninstall before upgrading, or combine an older -base with a newer core)
• multiqueue: add support for buffering mode where we post BUFFERING messages based on the level of the queues
• typefind: speed up typefinding a lot by first trying the typefinder for the file's extension
• buffer: remove private/internal subbuffer subclass and keep track of the parent buffer directly in the GstBuffer structure (this removes quite a bit of special-casing and will allow for future improvements/ extensions that are harder to do if there's a separate subbuffer class.
• collectpads: add ability to install clipping functions
• new tags for TV/Radio shows/episodes, lyrics, composer sortname and grouping
• miniobject: avoid race when recycling buffers
• basesrc: fix race in PLAYING->PAUSED->PLAYING
