 The automatic selection of the pixel format has been recently changed to
 reduce the possible loss of information:

 Author: Michael Niedermayer <michaelni at gmx.at>

     avfilter/ff_merge_formats: only merge if doing so does not loose

 specifics needs, you have to express them to ffmpeg with the corresponding
 option, there is no "do what I mean" option.
