Sebastian Dröge 27fb7d380a Add property for enabling/disabling of RP188 receival/transmission
Enabling this can lead to frame drops in certain setups so enabling it
always is not ideal.

GStreamer AJA source/sink plugin

GStreamer plugin for AJA capture and output cards.

This plugin requires the NTV2 SDK version 16 or newer.

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
