Release notes for GStreamer Good Plug-ins 0.10.31 "Faster" The GStreamer team is proud to announce a new release in the 0.10.x stable series of the GStreamer Good Plug-ins. The 0.10.x series is a stable series targeted at end users. "Such ingratitude. After all the times I've saved your life." A collection of plug-ins you'd want to have right next to you on the battlefield. Shooting sharp and making no mistakes, these plug-ins have it all: good looks, good code, and good licensing. Documented and dressed up in tests. If you're looking for a role model to base your own plug-in on, here it is. If you find a plot hole or a badly lip-synced line of code in them, let us know - it is a matter of honour for us to ensure Blondie doesn't look like he's been walking 100 miles through the desert without water. This module contains a set of plug-ins that we consider to have good quality code, correct functionality, our preferred license (LGPL for the plug-in code, LGPL or LGPL-compatible for the supporting library). We believe distributors can safely ship these plug-ins. People writing elements should base their code on these elements. Other modules containing plug-ins are: gst-plugins-base contains a basic set of well-supported plug-ins 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 * audioparsers: propagate downstream caps constraints upstream * ac3parse: add support for IEC 61937 alignment and conversion/switching between alignments * ac3parse: let bsid 9 and 10 through * auparse: implement seeking * avidemux: fix wrong stride when inverting uncompressed video * cairotextoverlay: add a "silent" property to skip rendering; forward new segment events * deinterlace: add support for deinterlacing using buffer caps/flags (as set by e.g. fieldanalysis) * deinterlace: new fieldanalysis-related properties: "locking" and "ignore-obscure" * directsoundsink: fix negotiation/device setup: 16-bit audio is signed, 8-bit is unsigned * effecttv: fix reverse negotiation; repair color modes in radioactv by taking rgb,bgr into account * equalizer: also sync the parameters for the filter bands * flacdec: better timestamp/offset handling; try upstream first for duration queries * flacdec: send EOS when seeking after the end of file instead of failing * flacenc: do not drop the first data buffer on the floor *

inverted pixel-aspect-ratio info on pixbufs * jack: add "client-name" property to jackaudiosink and jackaudiosrc * jpegdec: add sof-marker to template caps, so we don't get plugged for lossless jpeg *
