On DVDs, the palette is part of the IFO file and therefore
not available when reading from a dumped VOB file.

8bf16e677f ffv1enc: allow encoding with 1 slice for CIF and smaller in version 3 
the default is still 4 slices for any resolution, this just allows the user
to force 1 slice.
This in my quick test improves compression by 1% for a 320x240 sample

c9ff32215b lavu/opt: allow to set sample and pixel format with av_opt_set_int() 
This change requires the user to specify min and max value, and makes
possible to prevent the user to set AV_{SAMPLE,PIX}_FMT_NONE if
forbidden.

Add required ifdeffery in case of mixed libraries, when libavutil is
updated but not the other libraries.

This is a followup of 08d0969c1402ccec4dce44bd430128fb59d7b790.
