 null pointer segfaults
 dont print redundant spam
 dont print prefix if reference==NULL
 class -> av_class
 dont copy AVClass to every object, its a waste of memory and not a good idea at all

(f)printf() is disallowed in libavcodec, compilation will fail now if its used, except that codecs which where added after the printf->av_log change which did ignore av_log() and used prinf are now silent and wont print anything, they should be changed to use av_log, i could do that, but its better if the orginal developer decides which AV_LOG level each message should get

  - the first audio and video packs now contain only a system header and lots
  of padding.
  - no system headers in any packs other than the first ones
  - the two system headers only contain information about "their" stream
  - fixed some header values (muxrate, some flags, ...) so that they have the
  values specified by the standard
  - padding packs are inserted if the mux rate would be below 75 packs per
  second (the rate must not be below or above that value).
  - fixed the SCR of the packs
  - 20 zero bytes are now inserted at the end of each audio pack, after the
  data packet
