Missing aspect ratio metadata

[flossy83]

Hi

For some reason LwLibavVideoSource isn't detecting the aspect ratio of this clip, while FFVideoSource, Directshow LAV decoder and MediaInfo are successful.

Test clip: https://drive.google.com/uc?export=download&id=1KnW7FDPEYltp9ugEKVSY2u2tQoC-ZjHV

sourcefile = "motorworld.mkv"
left = LWLibavVideoSource(sourcefile).PropShow()
right = FFVideoSource(sourcefile).PropShow()
StackHorizontal(left, right)

LWLibavVideoSource on left, FFVideoSource on right (_SARDen/_SARNum should be 180/197)

Thanks
