Is it possible to provide additional aspect ratio issues to the list SMPlayer presents by "Video/Aspect Ratio"? Perhaps in a text file somewhere?
This is possible with VLC. I use it to add aspect ratios that stretch the width to compensate for ITU underscan in old rips of DVD-s that did not have black bars on the sides cropped.
To be sure folks understand, see for example "Analog to digital resolution issues" here: https://en.wikipedia.org/wiki/Overscan
Handbrake CLI for example has an option for dealing with this. See "--itu-par" here: https://handbrake.fr/docs/en/1.1.0/cli/cli-guide.html
I often encounter such old uncropped DVD rips, where the DVD was under scanned by the 704/720 ITU ration. Or something close anyway. To my eye this is noticeable.
So I added three aspect ratios to VLC to compensate, width-stretched by 720/704=45/44. I stretched 4x3, 3x2 and 16x9 to get 45x44(=15x11), 135x88 and 60x33(=20x11), respectively.
If this is not possible, how about allowing this sort of customization in a future release? Thanks.
