Release notes for GStreamer Base Plug-ins 0.10.26 "You will know when you get there"

Features of this release

• playbin2: make about-to-finish signal work for raw sources (e.g. audio CDs)
• playbin2: fix handling of the native audio/video flags
• playbin2: add flag to enable decodebin buffering
• playbin2: make subtitle error handling more robust and ignore late errors
• playbin2: improve subtitle passthrough in uridecodebin
• playbin2: new subtitleoverlay element for generic subtitle overlaying
• playbin2: proxy notify::volume and notify::mute from the volume/mute elements (or audio sink)
• playbin2: don't stop completely on initialization errors from subtitle elements; instead disable the subtitles and play the other parts of the stream
• decodebin2: rewrite autoplugging and how groups of pads are exposed
• uridecodebin: add use-buffering property that will perform buffering on parsed or demuxed media.
• GstXOverlay: flesh out docs and add example for use with Gtk+ >= 2.18
• libgsttag: add utility functions for ISO-639 language codes and tags (packagers: this entails a new soft dependency on the iso-codes package)
• oggdemux: use internal granulepos<->timestamp mapper and make oggdemux more like a 'normal' demuxer that outputs timestamps
• oggdemux: seeking improvements
• subparse: add qttext support
• ffmpegcolorspace: prefer transforming alpha formats to alpha formats and the other way around
• libgstvideo: add functions to create/parse still frame events.
• theoraenc: make the default quality property 48.
• videotestsrc: add pattern with out-of-gamut colors
• theora: port to 'new' theora 1.0 API; make misc. existing properties have no effect (quick, keyframe-mindistance, noise-sensitivity, sharpness, keyframe_threshold); those either never worked or aren't needed/provided/useful any longer with the newer API
• typefinding: misc. performance improvements and fixes
• baseaudiosink: make drift tolerance configurable
