How do I get rstpscr connected to detect.py using Gstreamer

[PushkarChatterji]

Hi,

I am am able to connect to my wifi camera using the Gstreamer cli:

gst-launch-1.0 rtspsrc location=rtsp://admin:REDACTED@192.168.1.100/live/profile.0 ! decodebin ! autovideosink

This works just fine and is able to display the live feed from the wifi cam on the monitor connected to the Coral Dev Board via HDMI.

However, I am not able to figure out the equivalent pipeline that I should use in gstreamer.py to get detect.py to run off the wifi cam feed.

Any tips would be super helpful!

My setup:

I am using the Coral Dev Board with a monitor connected to it via HDMI and I am running commands in a 'mdt shell' terminal window on my host PC (Ubuntu 18.04) which is connected to the Coral Dev Board via USB-c.

Quick update:

I changed the code in gstreamer.py as under:

commented-out code is the original code

`def run_pipeline(user_function, src_size=(640,480), appsink_size=(320, 180)):
    PIPELINE = 'rtspsrc location=rtsp://admin:REDACTED@192.168.1.100/live/profile.0 ! decodebin ! {leaky_q} '
    #PIPELINE = 'v4l2src device=/dev/video1 ! {src_caps} ! {leaky_q} '
    if detectCoralDevBoard():
        #SRC_CAPS = 'video/x-raw,format=YUY2,width={width},height={height},framerate=30/1'
        SRC_CAPS = 'video/x-raw,width={width},height={height},framerate=30/1'
        PIPELINE += """ ! glupload ! tee name=t
            t. ! {leaky_q} ! glfilterbin filter=glcolorscale
               ! {dl_caps} ! videoconvert ! {sink_caps} ! {sink_element}
            t. ! {leaky_q} ! glfilterbin filter=glcolorscale
               ! rsvgoverlay name=overlay ! waylandsink
        """
  `

This seems to work for me.

I am hoping that with this we can use Gstreamer on the Coral Dev Board to connect to wifi cams as feed for inference.
