/**
* SECTION:element-ajasrc
*
* Source element for [AJA](https://www.aja.com) output cards.
*
* ## Example usage
*
* Output a 1080p2997 test audio/video stream
*
* ```sh
* gst-launch-1.0 videotestsrc pattern=ball ! video/x-raw,format=v210,width=1920,height=1080,framerate=30000/1001,interlace-mode=progressive ! timeoverlay ! timecodestamper ! combiner.video \
* audiotestsrc freq=440 ! audio/x-raw,format=S32LE,rate=48000,channels=16 ! audiobuffersplit output-buffer-duration=1/30 ! combiner.audio \
* ajasinkcombiner name=combiner ! ajasink channel=0
* ```
*
* Capture 1080p30 audio/video and directly output it again on the same card
*
* ```sh
* gst-launch-1.0 ajasrc video-format=1080p-3000 channel=1 input-source=sdi-1 audio-system=2 ! ajasrcdemux name=d \
* d.video ! queue max-size-bytes=0 max-size-buffers=0 max-size-time=1000000000 ! c.video \
* d.audio ! queue max-size-bytes=0 max-size-buffers=0 max-size-time=1000000000 ! c.audio \
* ajasinkcombiner name=c ! ajasink channel=0 reference-source=input-1
* ```
*
* Since: 1.24
