/**
* SECTION:element-interlace
*
* The interlace element takes a non-interlaced raw video stream as input,
* creates fields out of each frame, then combines fields into interlaced
* frames to output as an interlaced video stream.

* <refsect2>
* <title>Example launch line</title>
* |[
* gst-launch -v videotestsrc pattern=ball ! interlace ! xvimagesink
* ]|
* This pipeline illustrates the combing effects caused by displaying
* two interlaced fields as one progressive frame.
* |[
* gst-launch -v filesrc location=/path/to/file ! decodebin ! videorate !
* videoscale ! video/x-raw-yuv,format=\(fourcc\)I420,width=720,height=480,
* framerate=60000/1001,pixel-aspect-ratio=11/10 !
* interlace top-field-first=false ! ...
* ]|
* This pipeline converts a progressive video stream into an interlaced
* stream suitable for standard definition NTSC.
