1.2.0 - 2015-10-01

Fixed

• Support ISO-BMFF files with trailing 'moov' boxes.

  • For video adaptation sets, added @maxWidth/@width, @maxHeight/@height, @maxFrameRate/@frameRate and @par attributes;

  • Added cenc:default_KID and cenc:pssh to ContentProtection elements;
  • Moved ContentProtection elements up to AdaptationSet element, controlled by --generate_dash_if_iop_compliant_mpd;
  • Moved representations encrypted with different keys to different adaptation sets, grouped by @group attribute, controlled by --generate_dash_if_iop_compliant_mpd.
• Fixed SSL CA cert issue on CentOS.
• Fixed a couple of packager crashes on invalid inputs.
• Read enough bytes before detecting container type. This fixed MPEG-TS not recognized issue on some systems.
• Generate proper tkhd.width and tkhd.height with non-square pixels.
• Support composition offset greater than (1<<31).
