  avcodec/mpegvideo_dec: Move memcpy'ing ctx to mpeg4videodec.c
  
  When the destination MpegEncContext in ff_mpeg_update_thread_context()
  is not initialized, the source MpegEncContext is simply copied
  over it before (potentially) calling ff_mpv_common_init().
  This leads to data races when this code is executed which is why
  it should be replaced with only copying the necessary fields
  (this is for future commits).
  
  Given that the RV30 and RV40 decoders always call said function
  with an already initialized MpegEncContext (they use context_reinit
  in case of frame size changes), they don't need this ugly
  initialization (and are therefore race-free). This means that
  this code can be moved to the only decoder that actually needs it:
  MPEG-4. This commit does so.

  avformat/dump: Stream start offsets: change precision and label
  
  - Change precision to 6 digits to align with other printed times
  - Change label to just "Start"
  - Add 's' unit to format 'start' value for consistency

  avcodec/cbs_apv: don't return an error when reading empty buffers
  
  The output will be a fragment with zero units, which is a lot more user friendly
  than making them think something went wrong, as it already happens with cbs_av1.

  avcodec/cbs: add an AVBufferRef input argument to ff_cbs_read()
  
  To allow taking a reference from an existing buffer outside of AVPackets.
