Despite the warnings, the pipeline appears to
work, but I would prefer <br>
it to not spam warnings continuously :) Any
ideas? This is on Ubuntu <br>

<p>It's a very common Logitech C920 webcam (but I've
seen the same message with a Z-Cam M3 camera). I think

<p>Gstreamer is built from source, from the 1.20.3 tag.</p>
<p>I have also just built it from main (commit
0e551871c45a1b9fd67d99d2d4f31a983f1b3217) and that shows the
effect as well.</p>
