I am trying to upload a video that is 640 x 480. Using FFmpeg I am trying to resize to a square but I am having much difficulty.

if i use s=320x320 in my command or scale 320x320

    ->setVideoScale(320, 320)

the image is distored.

If i change the aspect ratio 1:1 i get black bars.

is there a way to actually just cut a RECT in the video. IE i want to be able to re save the video and it only capture

   x 0 to 320
   y 0 to 320  

or whatever bounds I pick.

Basically I do not want to re-size I just want to be able to re record a certain portion of the video. is this possible?
