I need to capture a stereo video using a Decklink card. The two channels are combined for a side-by-stereo for the viewer but I also need the unmodified videos for data collection. My gst-launch line looks like:
gst-launch
gst-launch-1.0 \ decklinkvideosrc device-number=1 connection=sdi mode=1080i5994 ! deinterlace method=greedyh ! tee name=t1 \ decklinkvideosrc device-number=0 connection=sdi mode=1080i5994 ! deinterlace method=greedyh ! tee name=t0 \ t1. ! queue ! c. \ t0. ! queue ! c. \ compositor name=c \ sink_0::xpos=0 sink_0::ypos=0 sink_0::width=960 sink_0::height=1080\ sink_1::xpos=960 sink_1::ypos=0 sink_1::width=960 sink_1::height=1080 ! \ video/x-raw,width=1920,height=1080 ! \ autovideosink \ t1. ! queue ! autovideosink \ t0. ! queue ! fpsdisplaysink video-sink=autovideosink text-overlay=true
I have two tees and one compositor so 3 outputs. Is there any way to code this in a launch file? If not, I assume I will have to code this in C++.
