Before, it just returned width/height. Correct is width/height*sar.
That way it is consistent with DAR as in probe output and setdar.

- remove avplay -vismv option, which has not worked for a long time
- Live HDS muxer
- setsar/setdar filters now support variables in ratio expressions
+- dar variable in the scale filter now returns the actual DAR (i.e. a * sar)
version 9:
@item ow, oh
same as @var{out_w} and @var{out_h}
-@item dar, a
-input display aspect ratio, same as @var{iw} / @var{ih}
+@item a
+same as @var{iw} / @var{ih}
@item sar
input sample aspect ratio
+@item dar
+input display aspect ratio, it is the same as (@var{iw} / @var{ih}) * @var{sar}
+
@item hsub, vsub
horizontal and vertical chroma subsample values. For example for the
pixel format "yuv422p" @var{hsub} is 2 and @var{vsub} is 1.
