* vf_scale: make the dar variable return the DAR.Rudolf Polzer2013-11-02
| | | | | | | | | Before, it just returned width/height. Correct is width/height*sar. That way it is consistent with DAR as in probe output and setdar. Signed-off-by: Rudolf Polzer <divverent@xonotic.org> Signed-off-by: Anton Khirnov <anton@khirnov.net>

* lavfi: merge avfiltergraph.h into avfilter.hAnton Khirnov2013-04-11
