  • frei0r - Enable frei0r wrapping in libavfilter

  • gpl - Build GPL code. Should be enabled unless you require LGPL binaries.
  • gsm - Add support for the gsm lossy speech compression codec
  • hardcoded-tables - Use pre-calculated tables rather than calculating them on the fly. It results in an increase of approximately 15% in the size of libavcodec, the main library impacted by this change. It enables savings in table generation time, done once at codec initialization, since by hardcoding the tables, they do not need to be computed at runtime. However, the savings are often negligible (~100k cycles is a typical number) especially when amortized over the entire encoding/decoding operation. Improvements are being made to the runtime initialization, and so over time, this option will have an impact on fewer and fewer codecs.
