MPEG2 PS sample: wrong aspect ratio

Reported by: Underground78 Owned by:

Version: git-master Keywords: aspect
Cc: Blocked By:
Blocking: Reproduced by developer: yes
Analyzed by developer: no

Description

Summary of the bug:
This sample is detected as 4:3 by FFmpeg although it apparently should be 16:9. WinDVD plays it with the expected aspect ratio of 16:9 and MediaInfo? also reports it to be 16:9.

How to reproduce:

> ffmpeg -i "VR_MOVIE_GuyMartinsSpitfireBcast169 qsf lappyAspectNoChnge_extract.mpg"

WMP starts the file 4:3 as MPlayer, vlc and FFplay do, after a moment it changes the aspect ratio to 16:9.
