Stream #0.0(eng): Video: svq3, yuvj420p, 648x486, 1577 kb/s, SAR 43185:32768
DAR 14395:8192, 29.91 fps, 29.95 tbr, 29954 tbn, 29954 tbc
the wxh shows ~4:3 SAR is also ~4:3 yet DAR is ~16:9 
the actual video plays at ~16:9 or 854x486
the only dimension reported here evenly div by 4 is 648 which makes me think
ffmpeg isn't so much reading the dimensions as it is calculating them?
Still learning
