1 This is GStreamer Bad Plugins 1.3.2
6 • GstMessageType has GST_MESSAGE_EXTENDED added. All types before
7 that can be used together as a flags type as before, but from
8 that message onwards the types are just counted incrementally.
9 This was necessary to be able to add more message types.
10 In 2.0 GstMessageType will just become an enum and not a flags
12 • GstDeviceMonitor for device probing, e.g. to list all available
13 audio or video capture devices. This is the replacement for
14 GstPropertyProbe from 0.10.
15 • Events accumulate the running-time offset now when travelling
16 through pads, as set by the gst_pad_set_offset() function. This
17 allows to compensate for this in the QOS event for example.
18 • GstBuffer has a new flag "tag-memory" that is set automatically
19 when memory is added or removed to a buffer. This allows buffer
20 pools to detect if they can recycle a buffer or need to reset
22 • GstToc has new API to mark GstTocEntries as loops.
23 • A not-authorized resource error has been defined to notify
24 applications that accessing the resource has failed because
25 of missing authorization and to distinguish this case from others.
26 This change is actually already in 1.2.4.
27 • GstPad has a new flag "accept-intersect", that will let the default
28 ACCEPT_CAPS query handler do an intersection instead of subset check.
29 This is interesting for parser elements that can handle incomplete
31 • GstCollectPads has support for flushing and a default handler for
33 • GstSegment has new API to offset the running time by a specific
34 value and this is used in GstPad to allow positive and negative
35 offsets in gst_pad_set_offset() in all situations.
36 • Support for h265/HEVC and VP8 has been added to the codec utils and codec
37 parsers library, and was integrated into various elements.
38 • API for adjusting the TLS validation of RTSP connection has been added.
39 • The RTSP and SDP library has MIKEY (RFC 3830) support now, and
40 there is API to distinguish between the different RTSP profiles.
41 • API to access RTP time information and statistics.
42 • Support for auxiliary streams was added to rtpbin.
43 • Support for tiled, raw video formats has been added.
44 • GstVideoDecoder and GstAudioDecoder have API to help aggregating tag
45 events and merge custom tags into them consistently.
46 • playbin/playsink has support for application provided audio and video
48 • GstDiscoverer has new and simplified API to get details about missing
49 plugins and information to pass to the plugin installer.
50 • The GL library was merged from gst-plugins-gl to gst-plugins-bad,
51 providing a generic infrastructure for handling GL inside GStreamer
52 pipelines and a plugin with some elements using these, especially
53 a video sink. Supported platforms currently are Android, Cocoa (OS X),
54 DispManX (Raspberry Pi), EAGL (iOS), WGL (Windows) and generic X11,
55 Wayland and EGL platforms.
56 This replaces eglglessink and also is supposed to replace osxvideosink.
60 • New plugins and elements:
61 ∘ v4l2videodec element for accessing hardware codecs on
62 platforms that make them accessible via V4L2, e.g.
63 Samsung Exynos. This comes together with major refactoring
64 of the existing V4L2 elements and the corresponding
66 The v4l2videodec element replaces the mfcdec element.
67 ∘ New downloadbuffer element that replaces the download
68 buffering feature of queue2. Compared to queue2's code
69 it is much simpler and only for this single use case.
70 A noteworthy new feature is that it's downloading gaps
71 in the already downloaded stream parts when nothing else
73 This is now used by playbin when download buffering is
75 ∘ rtpstreampay and rtpstreamdepay elements for transmitting
76 RTP packets over a stream API (e.g. TCP) according to
78 ∘ rtprtx elements for standard compliant implementation of
79 retransmissions, integrated into the rtpmanager plugin.
80 ∘ audiomixer element that mixes multiple audio streams together
81 into a single one while keeping synchronization. This is
82 planned to become the replacement of the adder element.
83 ∘ OpenNI2 plugin for 3D cameras like the Kinect camera.
84 ∘ OpenEXR plugin for decoding high-dynamic-range EXR images.
85 ∘ curlsshsink and curlsftpsink to write files via SSH/SFTP.
86 ∘ videosignal, ivfparse and sndfile plugins ported from 0.10.
87 ∘ avfvideosrc, vtdec and other elements were ported from 0.10 and
88 are available on OS X and iOS now.
91 ∘ gst-libav now uses libav 10.1, and gained support for H265/HEVC.
92 ∘ Support for hardware codecs and special memory types has been
93 improved with bugfixes and feature additions in various plugins
95 ∘ Various bugfixes and improvements to buffering in queue2 and
97 ∘ dvbsrc supports more delivery mechanisms and other features
98 now, including DVB S2 and T2 support.
99 ∘ The MPEGTS library has support for many more descriptors.
100 ∘ Major improvements to tsdemux, especially time related.
101 ∘ souphttpsrc now has support for keep-alive connections,
102 compression, configurable number of retries and configuration
103 for SSL certificate validation.
104 ∘ hlsdemux has undergone major refactoring and works more
105 reliable now and supports more HLS features like trick modes.
106 Also fragments are pushed downstream while they're downloaded
107 now instead of waiting for each fragment to finish.
108 ∘ dashdemux and mssdemux are now also pushing fragments downstream
109 while they're downloaded instead of waiting for each fragment to
111 ∘ videoflip can automatically flip based on the orientation tag.
112 ∘ openjpeg supports the OpenJPEG2 API.
113 ∘ gst-rtsp-server supports SRTP and MIKEY now.
114 ∘ Lots of fixes for coverity warnings all over the place.
115 ∘ 400+ fixed bug reports, and many other bug fixes and other
116 improvements everywhere that had no bug report.
118 Things to look out for:
119 • The eglglessink element was removed and replaced by the glimagesink
121 • The mfcdec element was removed and replaced by v4l2videodec.
122 • osxvideosink is only available in OS X 10.6 or newer.
