GStreamer AJA source/sink plugin
GStreamer plugin for AJA capture and output cards.
This plugin requires the AJA NTV2 SDK version 16 or newer.
The location of the SDK can be configured via the aja-sdk-dir meson option.
If no location is given then the NTV2 SDK from
GitHub is compiled as a meson
subproject as part of the plugin.
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
Output a 1080p2997 test audio/video stream
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
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
