Video Codecs:
  MPEG-1							- 1991 (patent expired)
  MPEG-2 (H.262)					- 1996 (patent expired)
  H.263 (low bitrate telephony)		- 1996
  MPEG-4 part 2						- 1999 (patent expired)
  AVC (H.264, MPEG-4 part 10)		- 2004 (many different patents in a pool, some expired)
  Theora							- free (2004, last update 2011)
  VP7								- 2005 (On2), on par with H.264/AVC
  VP8								- 2008
  Dirac								- 2008
  MPEG Proposals for Internet video coding (web), 2011:
	  WVC				- apple/cisco/fraunhaffer proposal: MPEG-4 AVC profile
	  VCB				- google proposal: (is VP8)
	  IVC				- MPEG created, but free (2011, released 2015?)  (beats WVC and VCB)
  HEVC (H.265, MPEG-H part 2)		- 2013, patented
  VP9								- 2013, free
  AV1								- 2018, free
  VVC (H.266, MPEG-I part 3)		- 2020, patented


As of 2024
  Real-time streaming
	AVC (H.264)
    VP8

  Slow encoding, good compression+quality codecs:
    AV1 is about 50% less bits than H.264, 34% less than VP9
    	but very slow encoding (e.g. 0.05 fps)
    VP9 beats H.264, still <2 fps encoding
    HEVC is 20-50% less bits than H.264, needs more CPU and has less support.
    VVC is better than HEVC but requires payment.
