./multimedia/gst-plugins1-good, Open source multimedia framework - Good plugins

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 1.16.2nb1, Package name: gst-plugins1-good-1.16.2nb1, Maintainer: pkgsrc-users

GStreamer is a library that allows the construction of graphs of
media-handling components, ranging from simple Ogg/Vorbis playback to
complex audio (mixing) and video (non-linear editing) processing.

Applications can take advantage of advances in codec and filter technology
transparently. Developers can add new codecs and filters by writing a
simple plugin with a clean, generic interface.

GStreamer is released under the LGPL.

This package is part of the good GStreamer plugins; that is, those that are
considered to be stable and correctly coded.

Known Issues

    possibly breaking/incompatible changes to properties of wrapped FFmpeg \ 
decoders and encoders (see above).

    The way that GIO modules are named has changed due to upstream GLib natively \ 
adding support for loading static GIO modules. This means that any GStreamer \ 
application using gnutls for SSL/TLS on the Android or iOS platforms (or any \ 
other setup using static libraries) will fail to link looking for the \ 
g_io_module_gnutls_load_static() function. The new function name is now \ 
g_io_gnutls_load(gpointer data). See Android/iOS sections above for further \ 
details.

gstreamer1: updated to 1.16.0

GStreamer 1.16.0:

Introduction
The GStreamer team is proud to announce a new major feature release in
the stable 1.x API series of your favourite cross-platform multimedia
framework!

As always, this release is again packed with many new features, bug
fixes and other improvements.

Highlights
-   GStreamer WebRTC stack gained support for data channels for
    peer-to-peer communication based on SCTP, BUNDLE support, as well as
    support for multiple TURN servers.
-   AV1 video codec support for Matroska and QuickTime/MP4 containers
    and more configuration options and supported input formats for the
    AOMedia AV1 encoder
-   Support for Closed Captions and other Ancillary Data in video
-   Support for planar (non-interleaved) raw audio
-   GstVideoAggregator, compositor and OpenGL mixer elements are now in
    -base
-   New alternate fields interlace mode where each buffer carries a
    single field
-   WebM and Matroska ContentEncryption support in the Matroska demuxer
-   new WebKit WPE-based web browser source element
-   Video4Linux: HEVC encoding and decoding, JPEG encoding, and improved
    dmabuf import/export
-   Hardware-accelerated Nvidia video decoder gained support for VP8/VP9
    decoding, whilst the encoder gained support for H.265/HEVC encoding.
-   Many improvements to the Intel Media SDK based hardware-accelerated
    video decoder and encoder plugin (msdk): dmabuf import/export for
    zero-copy integration with other components; VP9 decoding; 10-bit
    HEVC encoding; video post-processing (vpp) support including
    deinterlacing; and the video decoder now handles dynamic resolution
    changes.
-   The ASS/SSA subtitle overlay renderer can now handle multiple
    subtitles that overlap in time and will show them on screen
    simultaneously
-   The Meson build is now feature-complete (*) and it is now the
    recommended build system on all platforms. The Autotools build is
    scheduled to be removed in the next cycle.
-   The GStreamer Rust bindings and Rust plugins module are now
    officially part of upstream GStreamer.
-   The GStreamer Editing Services gained a gesdemux element that allows
    directly playing back serialized edit list with playbin or
    (uri)decodebin
-   Many performance improvements
