 I tried next command
 ffplay -i foobar.mp4 -vf vignette
 increase working memory and stoped by out of memory


 libavfilter/vf_vignette.c line 271
 in filter_frame() function.
 insert af_frame_free(&in) before "return" to prevent memory leak.

 old:
     return ff_filter_frame(outlink, out);

 new:
     av_frame_free(&in);
     return ff_filter_frame(outlink, out);
