   a change of aspect ratio. Factorized aspect ratio code. A change of
   aspect ratio is only supported in the mosaic_bridge module, not in
   transcode.

   transcoding, transcode will take our fmt_out as a fmt_in to libmpeg2.
   libmpeg2.c will then believe that the user has requested a specific
   aspect ratio, which she hasn't. Thus in case of aspect ratio change,
   we're screwed.

   causing problem with some compiler versions.

   due to a recent change of the default value in ffmpeg which used to be
   YUV 420P). Forward i_rate in case a transcode or display operation
   takes place after switcher.

   parameter to specify the sample aspect ratio of the destination
   background. In this case, one of {width, height} can be omitted (set
   to 0) and it will be calculated based on the PAR of the source and
   the SAR of the background.

   which caused problems in case an identical PID carried the PMTs of two
   programs, one selected and the other not.
