So far we took only the codec sample aspect ratio into account
and ignored the one from the stream when using libavfilter.

I wonder if we shouldn't always provide the information per-frame.
The patch doesn't seem wrong if we agree to keep the situation as is.
for now it mirrors a bit what is being done in video_image_display() in
case there is no lavfi usage:
/* XXX: use variable in the frame */
if (is->video_st->sample_aspect_ratio.num)
aspect_ratio = av_q2d(is->video_st->sample_aspect_ratio);

aspect_ratio =
av_q2d(is->video_st->codec->sample_aspect_ratio);
else
aspect_ratio = 0;
