• lavf : deprecate compute_pkt_fields2

  lavf : deprecate compute_pkt_fields2
  All encoders set pts and dts properly now (and have been doing that for
  
  a while), so there is no good reason to do any timestamp guessing in the
  
  muxer.
  The newly added AVStreamInternal will be later used for storing all the
  
  private fields currently living in AVStream.
