# ajasrc

Source element for AJA capture cards.

## Example usage

Capture 1080p30 audio/video and display it locally

    gst-launch-1.0 ajasrc video-format=1080p-3000 ! ajasrcdemux name=d \
        d.video ! queue max-size-bytes=0 max-size-buffers=0
    max-size-time=1000000000 ! videoconvert ! autovideosink \ d.audio ! queue
    max-size-bytes=0 max-size-buffers=0 max-size-time=1000000000 ! audioconvert !
    audioresample ! autoaudiosink

Capture 1080p30 audio/video and directly output it again on the same card

    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
