GStreamer 团队很高兴的发布了 1.6.0 版本，该版本主要值得关注的改进包括： Stereoscopic 3D and multiview video support Trick mode API for key-frame only fast-forward/fast-reverse playback etc. Improved DTS (decoding timestamp) vs. PTS (presentation timestamp) handling to account for negative DTS New GstVideoConverter API for more optimised and more correct conversion of raw video frames between all supported formats, with rescaling v4l2src now supports renegotiation v4l2transform can now do scaling V4L2 Element now report Colorimetry properly Easier chunked recording of MP4, Matroska, Ogg, MPEG-TS: new splitmuxsink and multifilesink improvements Content Protection signalling API and Common Encryption (CENC) support for DASH/MP4 Many adaptive streaming (DASH, HLS and MSS) improvements New PTP and NTP network client clocks and better remote clock tracking stability High-quality text subtitle overlay at display resolutions with glimagesink or gtkglsink RECORD support for the GStreamer RTSP Server Retransmissions (RTX) support in RTSP server and client RTSP seeking support in client and server has been fixed RTCP scheduling improvements and reduced size RTCP support MP4/MOV muxer acquired a new "robust" mode of operation which attempts to keep the output file in a valid state at all times Live mixing support in aggregator, audiomixer and compositor was improved a lot compositor now also supports rescaling of inputs streams on the fly New audiointerleave element with proper input synchronisation and live input support Blackmagic Design DeckLink capture and playback card support was rewritten from scratch; 2k/4k support; mode sensing KLV metadata support in RTP and MPEG-TS H.265 video encoder (x265), decoders (libav, libde265) and RTP payloader and depayloaders New DTLS plugin and SRTP/DTLS support OpenGL3 support, multiple contexts and context propagation, 3D video, transfer/conversion separation, subtitle blending New OpenGL-based QML video sink, Gtk GL video sink, CoreAnimation CAOpenGLLayerSink video sink gst-libav switched to ffmpeg as libav-provider, gains support for 3D/multiview video, trick modes, and the CAVS codec GstHarness API for unit tests gst-editing-services got a completely new ges-launch-1.0 interface, improved mixing support and integration into gst-validate gnonlin has been deprecated in favor of nle (Non Linear Engine) in gst-editing-services gst-validate has a new plugin system, an extensive default testsuite, support for concurrent test runs and valgrind support cerbero build tool for SDK binary packages gains new 'bundle-source' command Various improvements to the Android, iOS, OS X and Windows platform support 修复的 bug 有： Crashes in the gst-libav encoders were fixed More DASH-IF test streams are working now Live DASH, HLS and MS SmoothStreaming streams work more reliable and other fixes for the adaptive streaming protocols Reverse playback works with scaletempo to keep the audio pitch Correct stream-time is reported for negative applied_rate SRTP packet validation during decoding does not reject valid packets anymore Fixes for audioaggregator and aggregator to start producing output at the right time, and e.g. not outputting lots of silence in the beginning gst-libav's internal ffmpeg snapshot was updated to 2.8.1 cerbero has support for Mac OS X 10.11 (El Capitan) Various memory leaks were fixed, including major leaks in playbin, playsink and decodebin Various GObject-Introspection annotation fixes for bindings and many, many more GStreamer 1.6.0 发布，多媒体开发框架下载地址
