In python I process a mp4 video with
stream = cv2.VideoCapture(filename)
.
The video has a resolution of 1440x1080, but an a display aspect ratio of 16:9. This is how it comes from my sony camera.
To preserve the aspect ratio, I need to know it.
How can I get it?the display aspect ratio it with OpenCV?
ffmpeg -I tells me this:
Stream #0:0(und): Video: h264 (Main) (avc1 / 0x31637661), yuv420p(tv, bt709/bt709/iec61966-2-4), 1440x1080 [SAR 4:3 DAR 16:9]
