Hello, when I get jpeg format via capture method and set "use_video_port" to True, it executes very fast, but when I specify YUV as the format then it slows down significantly. Does the camera not use video port when I request raw data?
There is a LOT more data in YUV format than JPEG, more data = more time to transfer.
Contrary to popular belief, humorous signatures are allowed.
I've been saying "Mucho" to my Spanish friend a lot more lately. It means a lot to him.
Sorry, I was using picamera.array.PiYUVArray and I guess that was the reason of slowness. I am now using the regular way and yuv is actually faster than jpeg.
