<html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> </head> <body> Hello, I am trying to get video with gstreamer from a Flir Lepton thermal camera over SPI and I get a green screen. The captured frame is a numpy array of unint8 which I convert to Gst.Buffer and the pipeline I use is: <blockquote> appsrc emit-signals=True is-live=True caps=video/x-raw, format=RGB, width=640, height=480, framerate=9/1 ! videoconvert ! xvimagesink sync=false </blockquote> For the conversion I do: <blockquote> gst_buffer = utils.ndarray_to_gst_buffer(array) </blockquote> In fact,I am using jackersson's example (from <a href="http://lifestyletransfer.com/how-to-use-gstreamer-appsrc-in-python/">http://lifestyletransfer.com/how-to-use-gstreamer-appsrc-in-python/</a>) with a different source. The implementation is in Python on an nvidia Xavier. I tested the VoSPI with Opencv and I get correct output. I tried slight variations of the above pipeline, with ximagesink, autovideosink,less caps or GRAY8 format. Can someone help me with why I get green screen and how can I debug and fix it? </body> </html>
