Anton Khirnov 862f33c10e vf_scale: use the pixfmt descriptor API 
Avoid using AV_PIX_FMT_NB, since that hardcodes the number of pixel
formats into lavfi and will break when a shared lavu is updated, adding
new pixel formats.

Rudolf Polzer 3a14b160bd vf_scale: make the dar variable return the DAR. 
Before, it just returned width/height. Correct is width/height*sar.

That way it is consistent with DAR as in probe output and setdar.

Fix "Value 0.000000 for parameter 'srch' out of range"
error message when source or destination height is 1.

Note: since the av_opt_set_int() calls are not checked for
failure and the interlaced scalers are not actually used,
this error has no consequence apart from a frightening message
in the log.
