I am encoding movs with ffmpeg, and I can't seem to get it to produce anything that isn't either 16:9 or 4:3. I am cropping the sides quite a lot - 48 pixels on each from the original mpeg2 transport stream, which produces something a bit non-standard, closest to 3:2. If I set 16:9 in the video parameter autosize, it will stretch the image to fit. If I set anything else, incuding 3:2 or unconstrained, it jumps to 4:3 using the height as the base setting and ignoring the width.
Suggestions, please?
