I was discussing this with Tim earlier, and there was a little confusion. He meant V4L2_FIELD_SEQ_TB/BT, not V4L2_FIELD_INTERLACED. When I tried out 1080i50 with HDMI in and the i.MX6, I got something that looks like V4L2_FIELD_SEQ_TB. The question though is: are the field rows always arranged

HDMI field order

Greetings, I'm trying to understand the various field orders supported by v4l2 [1]. Do HDMI sources always use V4L2_FIELD_INTERLACED or can they support alternate modes as well? Regards, Tim [1] - https://www.linuxtv.org/downloads/legacy/video4linux/API/V4L2_API/spec/ch03s06.html
