Frequently Asked Questions
What standards govern the field order?
Field ordering can be set for M/NTSC or utilize specific fields like V4L2_FIELD_TOP and V4L2_FIELD_BOTTOM.
How does the system handle sequential field transmission?
It supports various explicit sequences, including standard interleaved formats (V4L2_FIELD_INTERLACED_BT / V4L2_FIELD_INTERLACED_TB) or direct top/bottom sequencing.
What is the general structure for defining multiple fields?
Field definition can be handled by referencing separate sequential types, utilizing V4L2_FIELD_ALTERNATE sequences.
