Gst-inspect-1.0 does not show qml6glsink although libgstqml6.so is available

Application Development

Built gstreamer 1.22.8 with Qt 6.6.1 in Ubuntu and got libgstqml6.so
gst-inspect-1.0 | grep qml
does not show qml6glsink. Why?

2

Pass the absolute path of the libgstqml.so file to gst-inspect-1.0, that might give some clues.

3

Also check with ldd, if there’s any missing library the plugin might depend on.

4

Checked and did not find missing libs. And libgstqml6.so is in the same location as libgstqmlgl(for Qt5).

Does it need any Qt6 plugins?

I wasn’t asking where the lib file is. Try this: gst-inspect-1.0 /path/to/the/libgstqml6.so

Thanks. gst-inspect-1.0 /opt/gstreamer/lib/gstreamer-1.0/libgstqml6.so works

I have export GST_PLUGIN_PATH=/opt/gstreamer/lib/gstreamer-1.0.
Why does gst-inspect-1.0 qml6glsink not work?

Dunno :slight_smile: Remove the registry cache file, should be in ~/.cache/gstreamer-1.0/ and try again?
