# 10/09/2020: GPAC 1.0.1
This release fixes build and installation issues in 1.0.0, as well as various bugs introduced during the migration to the filters architecture.
It also adds several small features:
- better ttml import
- better support for MPEGH audio
- support fur DASH UTCTiming
- manifest generation from pre-fragmented DASH/HLS mp4
- speed optimization in isobmf reading (normal and fragmented)
- improved JS API for the filter session
- core tools exposed as JS module (file io, bitstream, etc ...)
- android fixes
# 16/06/2020: GPAC 1.0
- Complete rewrite of GPAC streaming core:
* addition of a filter-based architecture, used by MP4Client and MP4Box.
* moving all decoders and demuxer plugins of MP4Client and most of MP4Box import/export code as filters for this new architecture,
* moving DASH/HLS segmenter to a filter
* moving MP4Client compositor and most of the GF_Terminal internals to a filter
* addition of a new application gpac, whose only purpose is to create and run filter chains
* removal of MP42TS and DashCast applications since these functionalities are provided by gpac
* deprecation of some features (widget management, MSE draft implementation for SVG media, UPnP, TEMI player support).
- Profile system allowing to override through a static file default options of all filters and libgpac core
- Alias system for gpac app to simplify your command lines
- Enhanced DASHer:
* Support for HLS and dual HLS / DASH generation
* Support for any input
* True low-latency mode for DASH
* Support for multiple periods
* Support for other segment formats (raw, mkv, webm currently tested)
- Input and outputs
* Generic pipe, TCP, UDP, and Unix Domain socket input and output
* RTSP server output
* HTTP output (client and server), supporting low latency DASH access
* Ad-hoc stream format called GSF to allow serialization to file, pipe or socket of a session (for distributed filter chains), supporting AES-128 CBC encryption.
- Raw audio (PCM) and video (RGB, YUV) reframers and exporters
- HEVC tile splitting and merging filters
- Compositor is a standalone filter (SVG/BIFS/VRML graphics in a filter chain)

- Support for MediaAccessEvent (spec still under development ??)
- Added support for user extensions (global class only) in JS through modules - cf gpac_js for sample code.

* RTP hinting /playback is not supported yet
- Support for SVG foreignObject - all GPAC supported content can be played in a foreign object
- Added automatic switch between 2D and 3D context for VRML/BIFS Inline node
- Basic support for DCCI queries:
* the DCCI object is exposed in scripts as 'DCCIRoot'
* the related document can be specified in GPAC configuration file in the [General] section with the 'EnvironmentFile' key
pointing to an XML file to use as the ontology context
* DCCI's propertyFilters are NOT supported yet.
- Added support for YCbCr OpenGL texturing (only tested with GL_MESA_ycbcr_texture)

- Changed 3D mesh object to be slightly more compact (colors and normal)
- Unified focus model for SVG and MPEG-4. MPEG-4 focus can only be used through tab/-tab (no north/east/.. navigation)
* The MPEG-4 focus is based on the groups (2D/3D) presenting interactive features (sensors)
* keyboard mapping for sensors is:
isOver triggered when focus moves in(isOver=TRUE) and out (isOver=FALSE)
isActive triggered when ENTER key is pressed (isActive=TRUE) and released (isActive=TRUE)
direction keys with or without SHIFT to simulate mouse move
* Layout node is considered as a sensor when scroll_rate is 0, so that the user can scroll the layout

# 21/07/06: GPAC 0.4.2

- iTune tagging support, (patch from Andrew Voznytsa with slight modif). Tagging can be done with MP4Box -itags option. The tags are passed in a single string, separated by ':', formatted as 'tag_name=tag_value'. Supported tags names are: album, artist, comment, compilation, composer, created, disk, encoder, genre, name, tempo, track, tracknum, writer.
NOTE: to make sure you mp4 is importable on an iPod, you must:
- use .m4a extension
- specify the right brands: MP4Box -brand "M4A " -ab mp42
This process is automated in MP4Box for all file with extension .m4a
- added MPEG-1/2 raw importing (extensions: .m1v and .m2v).

program-based import for MPEG-2 TS streams (MP4Box -add file.ts#program=ProgName).
- initial IPV6 support
- MP42AVI is now deprecated. MP4Client can now be used to produce uncompressed bmp/raw/AVI, dumping the complete presentattion rather than just BIFS scenes (audio is currently not extracted). Usage:
MP4Client -bmp 1-2.5-3 file.mp4 take screenshots of file.mp4 aty T=1, 2.5 and 3 seconds
MP4Client -avi -fps 15.0 -size 176x144 file.mp4 produces an uncompressed AVI of resolution 176x144, framerate 15
MP4Client -avi 4-10 file.mp4 produces an uncompressed AVI of the scene between 4 and 10 seconds
Check MP4Client man page for more details.
- added support for major brand versioning in MP4Box: "-brand GPAC:2" will set the major brand to GPAC, with a version of 2.
- regression tests (.bt and .x3dv) are now part of GPAC source tree
changed all audio and video media in regression tests.

- moved all language handling to both ISO 639-1 (2 char code) and 639-2 (3 char code), as 639-1 is used in SVG.
- removed old XML parser, all parsing now relies on a new GPAC SAX parser (avoid dependency on libxml when unneeded).
- support for progressive loading support for XMT and X3D files.
- new svg_in module using gpac sax parser (supports progressive loading too)
- cf configuration.html or man gpac for more info on progressive loading control
- added 'define' support in BT - to use it just do:
#define symbol blab labl a
and reuse the symbol in the BT text. This may be quite buggy, but it can be useful

static data (eg images) is not supported. The OD data must be embedded in the IOD a la ISMA.

# 28/07/05: GPAC 0.4.0 release
** GPAC is now licensed under LGPL. **
Massive code rewrite and repository reorganization in order to comply to some base coding style (cf gpac/doc/CODING_STYLE) have taken place
since previous release. Documentation is still a work in progress.
APIs are not backward compatible, but should now be in a frozen state/spelling for the most common tools (utils, MPEG-4 OD, IsoMedia and terminal APIs)
- Fixed FAAD multichannel support with latest FAAD CVS version (bug due to FAAD inner channel creation). Latest version should
support both multichannel and AAC radios.
- added support for normal drawing (for debug purposes) in 3D renderer
- adedd support for single instance of Osmo4/w32
- changed audio configuration options to "Number of buffers" and "TotalDuration"
- fixed old bug in audio renderer screwing up the audio from time to time
- moved ffmpeg to latest CVS version (25/07/05). THIS VERSION IS NO LONGER COMPATIBLE with previous ones used in GPAC, update
your binaries!! Also updated ffmpeg plugin to new ffmpeg API
- moved all fullscreen handling to dedicated windows, refinement of wxOsmo4.
- more work on x11 plugin (events handling, 3D support) - THIS IS EXPERIMENTAL AT THIS RELEASE LEVEL, CHECKOUT CVS FOR BETTER SUPPORT...
- fixed anamorphic video handling in GPAC, both playing (2D and 3D) and MP4Box parsers (only done for MPEG-4 Visual, not AVC). Video is
now only rescaled at blit time
- changed ';' separators to ':' seprators in MP4Box (meta options and track import options) for linux prompt compatibility.
- misc fixes in tx3g track import, tx3g bt dump and couple of issues introduced in 0.3.0->0.4.0 migration
- misc cleanup of GF_VideoOutput interface.
- started doc manager using doxygen (doxyfile added in gpac/doc). APIs may be slightly reworked during the documentation phase.
Documentation will only be produced for libgpac, eg all exported headers in gpac/include/gpac
Development APIs documentation (gpac/include/gpac/internal) will come later.
- cleaned up IsoMedia reading for more efficient and more reliable parsing
- misc fixes in MP4Box option parsing, in RTP multicast setup

- integrated ogg lib in gpac (<gpac/m4_ogg.h>), and added ogg/vorbis and ogg/theora importers to mp4 - THIS IS NOT STANDARD AT ALL.
The current syntax is to put needed headers in the MPEG-4 DecoderSpecificInfo, with the following syntax:
u16 sizeof_header;
char *header_data;
for each header (quite similar to what is found in qtcomponents). Vorbis ObjectTypeIndication is 0xDE, theora ObjectTypeIndication is 0xDF.
Need some more testing before filing a request to mp4ra.org.
Streaming possible as MPEG-4 streams, Vorbis RTP packetizer still to be done.
