54 Features of this release
56 * GLib requirement is now >= 2.22, gobject-introspection >= 0.9.12
57 * New encodebin element
58 * New encoding profile and encoding targets API in pbutils
59 * audioresample: corrected buffer duration calculation to account for nonzero initial timestamp
60 * audioresample: provide as much valid output ts and offset as valid input
61 * audioresample: push half a history length, instead of a full history length, at end-of-stream so that output segment and input segment have same duration
62 * decodebin2: deprecate new-decoded-pad and removed-decoded-pad signals (use "pad-added" and "pad-removed" instead)
63 * multifdsink: add first and last buffer's timestamp to the stats; only keep last valid timestamp
64 * oggdemux: extract more tags (vorbis comment headers, Kate)
65 * oggdemux: ignore header pages when looking for keyframe; set headers on caps
66 * oggdemux: fix interpretation of Theora granule position and parsing of Theora size
67 * oggparse: Set DELTA_UNIT on buffers
68 * playbin2: delay stream-changed messages, fixing KATE subtitle recognition
69 * textoverlay: make text, xpos, ypos, color, and silent properties controllable
70 * typefinding: (E)AC-3 and ISO typefinder improvements; add yuv4mpeg typefinder
71 * typefinding: add "stream-format" to h264 caps, and framed=false to DTS caps
72 * typefinding: assume EBML files without doctype are matroska
73 * videorate: fix behaviour for frame rate cap changes
74 * vorbisdec: avoid using invalid timestamps; keep timestamps when no decoded output
75 * ximagesink, xvimagesink: add read-only window-width and window-height properties
76 * baseaudiopay: fix timestamps on buffer lists
77 * baseaudiosink: protect against ringbuffer disappearing while in a query
78 * basedepay: add support for buffer lists in the depayloader
79 * basertppay: use RTP base time when invalid timestamps
80 * rtpbuffer: relax arrangement for RTP bufferlists
81 * rtpdepayloader: add support for getting events
82 * rtppayload: copy applied rate to segment
83 * sdp: add method to check for multicast addresses
84 * sdp: only parse TTL for IP4 addresses
85 * video: add 8-bit paletted RGB, YUV9, YVU9 and IYU1 video formats
86 * video: return correct component width/height for A420
