Implementation of SVG support in GPAC is published

The underlying principles and algorithms of the SVG support in GPAC players is now published in the journal IEEE Transactions on Consumer Electronics

A presentation of GPAC will take place on thursday afternoon – don’t miss it!.

A brand new web site is available.

New features in this long-awaited release:

Initial Symbian support for GPAC
Massive memory optimizations for the 2D renderer and SVG scenes
Better LASeR support
ALSA output module
Linux DVB support
JPEG-2000 support through OpenJPEG library
Major improvements in the SAX parser
Support for multiple RTSP session per SDP
Global log system
mp4_streamer, a simple uni/multicaster for MP4/3GP files, working without hint tracks. This tool van also be used to simulate DVB-H service bursts
mp42ts, a draft MPEG-2 TS multiplexer. The multiplexer only supports MPEG-2 Video, MPEG-1 video and MPEG-1 audio. It is capable of outputing to a file or to a rtp/udp port. The source programs can either be local ISO Media files or SDP files describing a uni/multicast already setup (no RTSP support).
And of course the usual lot of bug fixes and other improvements …

Check the complete changelog.

This release has a lot of new features, among which:

GPAC plugins for both Mozilla and Internet Explorer browsers – look here for more details
Support for SmartPhone 2003 and PocketPC 2003 platforms, with experimental 3D support through OpenGL ES
Many SVG improvements (gradients, SVG 1.2 uDOM scripting, DOM events, etc.)
Draft MPEG-4 LASeR support – WARNING the LASeR standard is still under editing, INCLUDING bitstream syntax. This means that LASeR support in GPAC is completely experimental, encoded scenes will be broken in next release.
MP4Client now supports screenshots/raw avi extraction from any supported file (MP42AVI is now deprecated)
New media import/export XML-based format NHML extending NHNT capabilities
Configurable progressive rendering of all XML-based scene descriptions
Initial IPV6 support
MPEG-2 TS support (demultiplexer only) – this feature is under heavy development at the current time, this is more a “preview” than anything else, but it should be quite stable in MP4Box.
Support for VobSub subtitles in MP4Box (mux/demux) thanks to a great patch from Falco
MPEG-1/2 raw video import
Simple iTune tagging for MP4Box thanks to a patch from Andrew Voznytsa
And of course the usual lot of bug fixes and other improvements …
