Release notes for GStreamer 0.10.32 "Take Me to the Bonus Level"

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.

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

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

Features of this release

  • GLib requirement is now >= 2.22
  • New core element: valve (moved from -bad)
  • New core element: input-selector (N.B. without "select-all" property, use fsfunnel instead) (moved from -bad)
  • New core element: output-selector (with different negotiation behaviour by default, set pad-negotiation-mode=active for previous behaviour) (moved from -bad)
  • Performance improvements for many heavily-used code paths: GstPad, GstPoll, GstClock, GstTask, basesink, basesrc, queue2, multiqueue
  • gobject-introspection: add annotations for most core API
  • clock: make sync clock wait lockfree
  • fdsrc/fdsink: reenable on MSVC
  • registry: fix GStatBuf definition for win32 when building against older glib (fixes unnecessary rescanning of plugins at start-up)
  • element: add a more flexible way to get request pads from elements
  • multiqueue: return upon input when already eos
  • object: fix creation of default name (when creating more than 100000 elements)
  • pluginloader: fix hangs on OSX
  • poll: fixes for (p)select backend (used e.g. on OSX)
  • poll: refactor and make more lockfree; fixes for win32 and OSX (pselect backend)
  • registry: don't replace valid existing plugins by blacklisted ones
  • tags: don't produce duplicated entries when merging same value twice
  • basesink: preroll fixes for async=false case
  • basesink: rework position reporting code
  • basetransform: handle downstream giving a buffer with new caps but invalid size
