Hi, Looks like the Linux definition of the (packed) YUV444 format contradicts wikipedia. According to https://linuxtv.org/downloads/v4l-dvb-apis-new/uapi/v4l/pixfmt-packed-yuv.html The Linux V4L2_PIX_FMT_YUV444 format takes 16 bits per pixel, whereas the wikipedia https://en.wikipedia.org/wiki/YUV#Converting_between_Y.E2.80.B2UV_and_RGB says it's 24 bits per pixel. I understand that the wikipedia doesn't have an absolute authority, but I also saw other sources using the same definition. So, looks like some confusion is possible.
