How verify good/ugly/bad plugin is properly installed in Windows

Hi Nirbheek,

Thanks for the prompt response. Currently my system does not have environment variable for GST_REGISTRY, do I need to add them manually?

In addition, I would like to check how can we know which plugin is for which OS? Eg. I would like to try the uvsc264src plugin, but I was told that this plugin is for Linux only and not available in Windows. I could not find such information on its documentation page.
uvch264src - GStreamer<>
uvch264src. A camera bin src element that wraps v4l2src and implements UVC H264 Extension Units (XU) to control the H264 encoder in the camera

That leads me to think that whether my installation has installed all the plugins.

Thank you,

Hi Angela,

I've double-checked that all plugins are installed by the gstreamer
MSIs, specifically the playback plugin is installed too:


1. You only need to install either MinGW or MSVC. You do not need both.
2. Please make sure that you've installed both the runtime and
development installers for whichever version + toolchain you pick

If you've installed both MinGW and MSVC and/or you're switching
between them, you need to delete the gstreamer registry cache.
Alternatively, you can set the GST_REGISTRY env var to something like
C:/gstreamer/1.0/gstregistry-msvc-x86_64.bin etc.

But now when I try to run certain pipeline, it says 'no element or plugin' for certain element. May I know how to verify the base/good/ugly/bad plugin are properly installed in Windows?
