 (issue 1862, maybe a duplicate of ticket #1507)
 I will attach a sample with incorrect aspect ratio, plays correctly with:
 mplayer -demuxer real -vc rv3040
 mplayer -demuxer real -vc ffrv40
 mplayer -demuxer lavf -vc rv3040

 Incorrect aspect ratio with FFmpeg and:
 mplayer -demuxer lavf -vc ffrv40
