  RTMPTE protocol support
  RTMPE protocol support
  rtmp: Add ff_rtmp_calc_digest_pos()
  rtmp: Rename rtmp_calc_digest to ff_rtmp_calc_digest and make it global
  swscale: add missing HAVE_INLINE_ASM check.
  lavfi: place x86 inline assembly under HAVE_INLINE_ASM.
  vc1: Add a test for interlaced field pictures
  swscale: Mark all init functions as av_cold
  swscale: x86: Drop pointless _mmx suffix from filenames
  lavf: use conditional notation for default codec in muxer declarations.
