years ago there was a patch
that split aspect ration detection from for SMPTE 314M and IEC 61834.
i have a bunch of files that properly displayed by quicktime, but ffmpeg
report 16:9 aspect ratio for them.
files originally are IEC 68134[apt == 0] and apt=0, vsc_pack=CF so
they detected as 16:9, albeit Quicktime display it as 4:3.

(vsc_pack & 0x07) == 0x07)
really defines 16:9?
did not mention differences in aspect ration detection and meaning of
