GPAC 0.6.0

Overview of the community activity:

• Moved from Sourceforge to Github.
• ~1200 commits since 0.5.2.
• GPAC contains MP4Box, the MP4Client/Osmo4 player, and many other tools (MP42TS, etc.).
• Launched new projects such as MP4Box.js or Zenbuild.
• Built more free datasets based on GPAC (DASH, HEVC).

General:

• Improved very high resolutions, high framerate, and high colorspace (10 bits) playback support.
• HEVC top-notch support.
• Improved video playback through OpenGL and OpenGL ES.
• Video 360 navigation support on all platforms.
• Many adaptive streaming improvement (HLS and DASH), see specific section below.
• MP42TS (MPEG2-TS multiplexer) is production grade for adaptive streaming and reference vector streams.
• TEMI extension for fine synchronization and hybrid delivery (mandated by HbbTV 2.0).
• Better language tagging support.
• UTF16 name handling.
• Better multi-channel audio support.
• Improved support for encryption (CENC/PIFF - both AES CTR and CBC are supported).
• Improved generic support for subtitles (METX/METT, STPP TTML, WebVTT, SBTT, STXT, etc.).
• Parallel execution of GPAC tools.
• Better network support for TTL and multi-interface.
• SHVC (scalable) experimental (based on SHM4.1 and old ISOBMFF spec)

Dev:

• Improved security on the code.
• Memory tracker can display the stack.
• More examples of the API (player, demuxers, benchmarks, ...).

Build:

• Compatible with the latest dependencies (FFmpeg 3, etc.).
• Improved compatibility for toolchains (MSYS, MSYS2, Cygwin ; MSVC 2015 ; updated XCode ; updated Android and iOS build environments).
• Improved partial build.
• Static builds (including for the MP4Client player).

MP4Box:

• Added timescale change (:timescale=) and overwrite (:rescale=) in MP4Box importers.
• MP4Box to stdout with -std.
• Better id3v2 support.
• Better metadata handling.
• Options to change or swap trackIDs.
• -align-cat option.

MP4Client/Osmo4:

• Can display interactive animated graphics for statistics (buffer levels, resolutions for adaptive streaming, additional services, IOs, etc.)
• Mobile: several improvements. OpenGL ES2 support and better shaders.
• SVG animation and MediaSourceExtension support in SVG
• Hybrid playback (broadcast/broadband, scalable codecs, fine synchronization, GUI in MP4Client).
• Dektec output cards.

Adaptive streaming:

• Better HLS support (including startup improvement for huge VoD manifests).
• Industry profiles support: DASH-IF 2.0, HbbTV 1.5. Others on the roadmap.
• DASH segmenting: now cuts segments at average duration like other packagers. Less correct but improved player compatibility. Old behaviour with -dash-strict.
• DASH segmenting: insertion of custom DASH descriptors at various level of the MPD hierarchy, including SRD descriptors
• MP4Box can do stateful live packaging using -dash-live and -dash-ctx.
• Better SAP handling (from Type 1 to 6) aligned with MPEG latest documents.
• HDS preliminary support.
• SRD playback support for independent videos and HEVC independent tiles (file format still experimental), with various rate allocation strategies per tiles.
