Description
Summary of the bug:
When I try to crop e.g. the top right corner of a video into a png, the output is corrupted. I have to stay 10 ish pixels away from the right edge to make it work.
How to reproduce:
I am trying on a 1280x720 .mov prores video, I don't know if it matters.
crop=w=20:h=20:x=1260:y=0:exact=1:keep_aspect=0
Results in corrupted PNGs, whereas the following works just fine:
crop=w=20:h=20:x=1250:y=0:exact=1:keep_aspect=0
in stderr I see nothing that indicates there was an error

The output image has a column of black pixels at the right. Can be reproduced as follows:

I really don't know what was causing the issue. Seems to be gone now. Had to stay away from the border previously. This is the full command I was using.
ffmpeg.exe -ss 0us -i "../test_48_frames.mov" -an -frames:v 30 -vf "fps=fps=15:round=inf , crop=w=10:h=10:x=1270:y=0:exact=1:keep_aspect=0 , setsar=1 , scale=10:10" ".../%d.png"

Replying to wesnet12345:

Crazy output. Full command line for reproducing:
ffmpeg -i test_48_frames_only.mov -vf crop=w=5:h=5:x=1275:y=0:exact=1 -frames 1 -y out.png
Simple prores mov file that I am using for the test in case you don't have one.
