hi,
years ago there was a patch
http://git.libav.org/?p=libav.git;a=commitdiff;h=6aafe463e5d1483b95ad259334c45d2741c92fb2
that splits aspect ratio detection for SMPTE 314M and IEC 61834.
i have a bunch of files that properly displayed by quicktime, but ffmpeg
(dv decoder) report 16:9 aspect ratio for them.
files originally are IEC 68134[apt == 0] and apt=0, vsc_pack[2]=CF so
they detected as 16:9, albeit Quicktime display it as 4:3.
if somebody has IEC 61834 pdf's could he confirm that
(vsc_pack[2] & 0x07) == 0x07)
really defines 16:9?
at least
http://msdn.microsoft.com/en-us/library/dd407313%28v=vs.85%29.aspx did
not mention differences in aspect ration detection and meaning of filed
*DISP*
