Strange results in my "go to" test file with "guessed". See bold below.
file path: /root/media1/Britney Spears - Pepsi Commercial with Bob Dole.mpeg 15817144 bytes info: format: mpeg
1 video stream vid0 (0), id 0x000001: video1 mpeg1video 352x240 29.97 pix yuv420p interlace (container level): 1 interlace (codec level): -1 color space:unknown/ range:tv *Guessed SAR: 200:219, DAR: 880:657 * 2712+0 frms 90.51 secs 0:01:30.51
from wcalc console calculator:
-> 880/657 = 1.33942
so ... it just different representation?
There is code in mwindow.C that does display aspect ratio calculations ..... May be I can reuse that for more user-friendly display .....
I also tried to just reduce max number (1024*1024) it allowed to reduce to just 100. May be it will work better ... ? currently testing.
While "mediainfo" reports what I consider to be correct:
Video ID : 224 (0xE0) Format : MPEG Video Format version : Version 1 Format settings : CustomMatrix / BVOP Format settings, BVOP : Yes Format settings, Matrix : Custom Format settings, GOP : Variable Duration : 1 min 30 s Bit rate mode : Constant Bit rate : 1 150 kb/s Width : 352 pixels Height : 240 pixels *Display aspect ratio : 4:3*

in ffmpeg asset detailed info
for files like HDV info is guessed, for files like mov / mp4 you sometimes can get detection working.
code lifted from dump.c and ffprobe.c
