v1.4.0

[1.4.0] - 2016-04-08

Added

• Added support for MacOSX (#65). Thanks to @nevil.
• Added support for Dolby AC3 and EAC3 Audio in ISO-BMFF (#64).
• Added support for language code with subtags, e.g. por-BR is now supported.
• Added a new optional flag (--include_common_pssh) to widevine encryption
  to include common system pssh box in addition to
  widevine pssh box.
• Improved handling of unescaped NAL units in byte stream (#96).

Changed

• Changed fixed key encryption to generate
  common system pssh box by default; overridable by
  specifying pssh box(es) explicitly with --pssh flag, which is now optional.
  --pssh should be one or more PSSH boxes instead of just pssh data in hex
  string format if it is specified.
• Improved subsample encryption algorithm for H.264 and H.265. Now only video
  data in slice NALs are encrypted (#40).

Fixed

• Split AdaptationSets by container and codec in addition to content_type,
  language. AVC/MP4 and VP9/WebM are now put in different AdaptationSets if
  they are packaged together.
• Fixed index range off-by-1 error in WebM DASH manifest (#99).
• Fixed WebM SeekHeader bug that the positions should be relative to the
  Segment payload instead of the start of the file.
