GstVideoInterlaceMode

all frames are progressive

2 fields are interleaved in one video frame. Extra buffer flags describe the field order.

frames contains both interlaced and progressive video, the buffer flags describe the frame and fields.

2 fields are stored in one buffer, use the frame ID to get access to the required field. For multiview (the 'views' property > 1) the fields of view N can be found at frame ID (N * 2) and (N * 2) + 1. Each field has only half the amount of lines as noted in the height property. This mode requires multiple GstVideoMeta metadata to describe the fields.

1 field is stored in one buffer, @GST_VIDEO_BUFFER_FLAG_TF or @GST_VIDEO_BUFFER_FLAG_BF indicates if the buffer is carrying the top or bottom field, respectively. The top and bottom buffers must alternate in the pipeline, with this mode (Since: 1.16).
