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
