No such element or plugin 'pylonsrc'

[harendracmaps]

I have compiled adn installed the libraries. but while running the following command gst-inspect-1.0 pylonsrc

I am facing the issue and pylonsrc is not getting detected.

No such element or plugin 'pylonsrc'.

Any help would be appreciated.

Linux distribution? Gstreamer version? How was gstreamer installed? Where is gstreamer installed? Is the plugin's .so file available in /usr/local/lib/gstreamer-1.0/ or ~/.local/share/gstreamer-1.0/plugins/? What happens if you run gst-inspect-1.0 with a path to the .so file? What was the output of sudo make install?

Thanks for responding. please fine the details as below. Linux : ARM64 GSTREAMER VERSION : GStreamer 1.8.3 gstreamer was installed using apt-get command.

Did you clear gstreamer cache? rm -rf ~/.cache/gstreamer-1.0 should do it iirc. Try gst-inspect-1.0 again after cleaning it. If not, note you'll need to clean the cache before you try do run any of the suggestions below.

If it doesn't work, does the rtspclientsink plugin you have in that directory show up when you try to gst-inspect-1.0 the plugin added by libgstrtspclientsink.so? If you move pylonsrc's .la and .so files to ~/.local/share/gstreamer-1.0/plugins, does it show up then? Does it work if you add GST_PLUGIN_SYSTEM_PATH=/usr/local/lib/gstreamer-1.0/ before the gst-inspect command (i.e. GST_PLUGIN_SYSTEM_PATH=/usr/local/lib/gstreamer-1.0/ gst-inspect-1.0 pylonsrc). Also try setting GST_PLUGIN_SYSTEM_PATH_1_0, GST_PLUGIN_PATH and GST_PLUGIN_PATH_1_0 variables with the same path. Also, you can also try the GST_DEBUG=*:6 environmental with gst-inspect-1.0 and see if that outputs anything useful (i.e. which paths your gstreamer scans for plugins).

Thanks ! Cleaning the cache does not solve the issue. But moving the .so .la in path ~/.local/share/gstreamer-1.0/plugins solved. Also if I set GST_PLUGIN_SYSTEM_PATH to /usr/local/lib/gstreamer-1.0/. then also it is working.

even though I closed the issue looks like it is not completely resolved. Either I am missing something in the command.

gst-launch-1.0 -v pylonsrc ! bayer2rgb ! videoconvert ! xvimagesink

First pipeline - you probably don't need the bayer2rgb. The camera I was using didn't have rgb output support (it was an early marketing sample). It should default to rgb and run just fine.

Second pipeline - Seems like your distro does not ship that plugin (it should be part of gst-plugins-base) or you don't have base plugins installed. You'll have to refer to your Linux distros documentations for that.
