Release 0.28.0
==============

This release needs recent FFmpeg (newer than 3.4) due to major refactoring.
Required library versions:

  * libavutil >= 56.6.100
  * libavcodec >= 58.7.100
  * libavformat >= 58.0.102
  * libswscale >= 5.0.101
  * libavfilter >= 7.0.101
  * libswresample >= 3.0.100

The LGPL 2.1+ relicensing process is now mostly complete. The remaining GPL-only
code (see Copyright file) can be disabled at build time by using --enable-lgpl.
