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
