Release notes for GStreamer 0.10.31 "Safety Pins"

The GStreamer team is proud to announce a new release in the 0.10.x stable series of the core of the GStreamer streaming media framework.

The 0.10.x series is a stable series targeted at end users. It is not API or ABI compatible with the stable 0.8.x series. It is, however, parallel installable with the 0.8.x series.

The 0.10.x series has been reworked for threadsafety. It also features various feature additions and enhancements.

This module, gstreamer, only contains core functionality. For actual media playback, you will need other modules.

gst-plugins-base
contains a basic set of well-supported plug-ins
gst-plugins-good
contains a set of well-supported plug-ins under our preferred license
gst-plugins-ugly
contains a set of well-supported plug-ins, but might pose problems for distributors
gst-plugins-bad
contains a set of less supported plug-ins that haven't passed the rigorous quality testing we expect

Features of this release

  • bin: add "message-forward" property to force forwarding of messages that would usually be filtered such as ASYNC_DONE or EOS
  • bin: improve tracking of source elements for more efficient event dispatch
  • bufferlist: add function to add a list of buffers
  • clock: fix racy shutdown clock id leak
  • element: add support for arbitrary element class / factory details
  • element: link_many should activate pads if needed
  • gst: add math-compat.h header
  • datetime: add GstDateTime API
  • elementfactory: add utility functions to filter features by type
  • plugin: load the gst-python plugin loader with G_MODULE_BIND_LAZY
  • query: add buffering ranges API to retrieve informations about the areas of the stream currently buffered
  • value: add int64 range type
  • info: write debugging output to file if GST_DEBUG_FILE environment variable is set
  • pad: use more efficient g_object_notify_by_pspec() for caps notifies if compiling against new-enough GLib
  • pipeline: If the currently used clock gets lost update it the next time when going from PAUSED to playing
  • plugin: add release datetime field to GstPluginDesc and set it if GST_PACKAGE_RELEASE_DATETIME is defined
  • utils: speed up pad linking utility functions by not trying pads that will never work
  • adapter: add function to get a list of buffers; support 0-sized buffers
  • adapter: optimize gst_adapter_take() and gst_adapter_peek() a little
  • basesink: only answer the SEGMENT query in pull mode
  • basesrc: return values in stream time for the POSITION query
  • basetransform: allow the subclass to add new fields to caps when getting new caps from downstream
  • basetransform: avoid useless memcpy
  • basetransform: upstream caps-renegotiation fixes
  • bitreader: add inlined and unchecked versions of the most important functions
  • bytewriter: add inline and unchecked variants of all important functions
  • bytewriter: fix possible infinite loop caused by an overflow
  • queue: add "silent" property to suppress signal emission (for better performance)
  • queue: avoid unnecessary g_cond_signal() (for better performance)
  • queue: push newsegment event when linking in PLAYING
  • queue2: extend ring buffer to support RAM mode
  • queue2: in download mode, prevent range corruption due to race
  • queue2: don't send seeks beyond the end of the file upstream in pull mode (fixes apple trailers and youtube/html5 playback in webkit)
  • multiqueue: flush the data queue if downstream return WRONG_STATE too
  • gst-inspect: print GST_PARAM_MUTABLE_* property flags
