-This is GStreamer Good Plugins 1.3.1
+This is GStreamer Good Plugins 1.4.0
Changes since 1.2:
caps.
• GstCollectPads has support for flushing and a default handler for
SEEK events now.
+ • New GstFlowAggregator helper object that simplifies handling of
+ flow returns in elements with multiple source pads. Additionally
+ GstPad now always stores the last flow return and provides an
+ API to retrieve it.
• GstSegment has new API to offset the running time by a specific
value and this is used in GstPad to allow positive and negative
offsets in gst_pad_set_offset() in all situations.
• Support for tiled, raw video formats has been added.
• GstVideoDecoder and GstAudioDecoder have API to help aggregating tag
events and merge custom tags into them consistently.
+ • GstBufferPool has support for flushing now.
• playbin/playsink has support for application provided audio and video
filters.
+ • GstDiscoverer has new and simplified API to get details about missing
+ plugins and information to pass to the plugin installer.
• The GL library was merged from gst-plugins-gl to gst-plugins-bad,
providing a generic infrastructure for handling GL inside GStreamer
pipelines and a plugin with some elements using these, especially
DispManX (Raspberry Pi), EAGL (iOS), WGL (Windows) and generic X11,
Wayland and EGL platforms.
This replaces eglglessink and also is supposed to replace osxvideosink.
+ • New GstAggregator base class in gst-plugins-bad. This is supposed to
+ replace GstCollectPads in the future and fix long-known shortcomings
+ in its API. Together with the base class some elements are provided
+ already, like a videomixer (compositor).
Major changes:
of the existing V4L2 elements and the corresponding
infrastructure.
The v4l2videodec element replaces the mfcdec element.
+ ∘ New downloadbuffer element that replaces the download
+ buffering feature of queue2. Compared to queue2's code
+ it is much simpler and only for this single use case.
+ A noteworthy new feature is that it's downloading gaps
+ in the already downloaded stream parts when nothing else
+ is to be downloaded.
+ This is now used by playbin when download buffering is
+ enabled.
∘ rtpstreampay and rtpstreamdepay elements for transmitting
RTP packets over a stream API (e.g. TCP) according to
RFC 4571.
are available on OS X and iOS now.
• Other changes:
- ∘ gst-libav now uses libav 10, and gained support for H265/HEVC.
+ ∘ gst-libav now uses libav 10.2, and gained support for H265/HEVC.
∘ Support for hardware codecs and special memory types has been
improved with bugfixes and feature additions in various plugins
and base classes.
∘ dvbsrc supports more delivery mechanisms and other features
now, including DVB S2 and T2 support.
∘ The MPEGTS library has support for many more descriptors.
- ∘ Major improvements to tsdemux, especially time related.
+ ∘ Major improvements to tsdemux and tsparse, especially time and
+ seeking related.
∘ souphttpsrc now has support for keep-alive connections,
compression, configurable number of retries and configuration
for SSL certificate validation.
reliable now and supports more HLS features like trick modes.
Also fragments are pushed downstream while they're downloaded
now instead of waiting for each fragment to finish.
+ ∘ dashdemux and mssdemux are now also pushing fragments downstream
+ while they're downloaded instead of waiting for each fragment to
+ finish.
∘ videoflip can automatically flip based on the orientation tag.
∘ openjpeg supports the OpenJPEG2 API.
+ ∘ waylandsink was refactored and should be more useful now. It also
+ includes a small library which most likely is going to be removed
+ in the future and will result in extensions to the GstVideoOverlay
+ interface.
∘ gst-rtsp-server supports SRTP and MIKEY now.
+ ∘ gst-libav encoders are now negotiating any profile/level settings
+ with downstream via caps.
∘ Lots of fixes for coverity warnings all over the place.
- ∘ 400+ fixed bug reports, and many other bug fixes and other
+ ∘ Negotiation related performance improvements.
+ ∘ 800+ fixed bug reports, and many other bug fixes and other
improvements everywhere that had no bug report.
Things to look out for:
element.
• The mfcdec element was removed and replaced by v4l2videodec.
• osxvideosink is only available in OS X 10.6 or newer.
-
+ • On Android the namespace of the automatically generated Java class
+ for initialization of GStreamer has changed from com.gstreamer to
+ org.freedesktop.gstreamer to prevent namespace pollution.
+ • On iOS you have to update your gst_ios_init.h and gst_ios_init.m in
+ your projects from the one included in the binaries if you used the
+ GnuTLS GIO module before. The loading mechanism has slightly changed.
