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
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?
Check out FFMPEG's video filters. There is a crop option that will do what you're asking for, specifically the first example.
Depending on the library you're using to interface with FFMPEG, something like the following might work per your example:
