GPAC 1.0

We are thrilled to announce the release of GPAC 1.0, the first official release of GPAC "filters", a complete re-architecture of GPAC streaming core.

You can have a quick overview of the new possibilities of GPAC in our fosdem 2020 talk or our MMSYS'20 presentation.

A lot of new things are present in this release:

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 spliting and merging filters.
Compositor is a standalone filter (SVG/BIFS/VRML graphics in a filter chain).
Image encoding support through libjpg and libpng.
Full FFMPEG support:
Encoding/decoding through FFMPEG libavcodec.
Multiplexing/demultiplexing through FFMPEG libavformat.
Device grabbers through FFMPEG libavdevice.
Raw audio and video filters through FFMPEG libavfilter.
Support for QuickJS (ES2020) and bindings for:
Complete filter API.
GPAC software rasterizer (EVG).
WebGL 1.0 Core.
XmlHttpRequest and uDOM APIs.
Storage.
Inspect and analyze filter.
MPEG-2 TS splitter.
Video cropper filter with zero-copy mode.
Video flip filter.
Source concatenation filter.
Simple audio and video output filters.
Experimental audio and video rewinder filter.
Encryption:
On-the-fly encryption and decryption, now available as filters.
Segment-based encryption and decryption.
ISOBMFF:
Box customization.
Better QT support, ProRes parsing and dumping.
Support for raw media (QT style or ISOBMFF for audio).
Simplify HEIF batch conversion through item to track mapping.
Reading from pipes (fragmented or progressive files).
Writing to packets rather than files.
Fast interleaved file creation mode with less storage requirements.
FileIO wrapper for cases where files are not stored in a file system known by GPAC.
Testing and Documentation:
Live doc generation (man and wiki).
Improved coverage.
Split test suite as dedicated repository.
Moved all resource to https://wiki.gpac.io.
Started howto pages on wiki.
Many bug fixes.
As usual, installers are available on gpac.io for most common platforms.
