0.86 (2018-01-09)
-----------------
New: Preliminary MXF support
New: Added a histogram in one-minute increments of the number of lines in a subtitle.
New: Added Autoconf build scripts for CCExtractor to generate makefiles (mac).
New: Added Autoconf build scripts for CCExtractor to generate makefiles (linux).
New: Added .rpm package generation script.
New: Added build/installation script for .pkg.tar.xz (Arch Linux).
New: Added tarball generation script.
New: Added --analyzevideo. If present the video stream will be processed even if the
subtitles are in a different stream. This is useful when we want video information
(resolution, frame type, etc). -vides now implies this option too.
[Note: Tentative - some possibly breaking changed were made for this, so if you
use it validate results]
New: Added a GUI in the main CCExtractor binary (separate from the external GUIs
such as CCExtractorGUI).
New: A Python binding extension so it's possible to use CCExtractor's tools from
Python.
New: Added -nospupngocr (don't OCR bitmaps when generating spupng, faster)
New: Add support for file split on keyframe (-segmentonkeyonly)
New: Added WebVTT output from Matroska.
New: Support for source-specific multicast.
New: FreeType-based text renderer (-out=spupng with teletext/EIA608).
