Gstreamer is not working (Windows)

So, I'm new to GStreamer and I've taken the safe route by downloading the pre-built binaries from https://gstreamer.freedesktop.org/download/ for windows. I believe I've installed it fully by downloading MSVC runtime and development versions for VS 2019. But when I try to run a GStreamer command I always get something similar to what is shown below.

Below is a snippet of the issue, when I run 'gst-device-monitor-1.0' via command line to access my built-in webcam as I'm running this on a work laptop.

I might be missing an environment variable or path. These are my current system variables, I've set:

My current PATH, I've set:

I was told the issue could be strawberryperl being above gstreamer in the path, but I've changed that since and the issue is still persistent.

System Info:

Windows 10 Pro 64-bit

Intel i5-5300U

8GB Ram

Re: Gstreamer is not working (Windows)

This can also happen if you've accidentally installed both the MSVC binaries and the MinGW binaries. You should only install one of them. What are the contents of C:\gstreamer\1.0\x86_64\bin ?

Basically you need to clear the plugin cache whenever you go between mingw and msvc builds.

Re: Gstreamer is not working (Windows)

In reply to this post by Michael Gouveia

I've tried to locate the cache but it doesn't exist.

This is the locations I tried on my system but the INetCache didn't exist even with hidden files showing

%USERPROFILE%\AppData\Local\Microsoft\Windows\INetCache\gstreamer-1.0\registry.x86_64.bin

I tried manually searching but no luck and even windows search box.

Assuming this is in regard to RTPBin, there is an action signal called "get-
session" with the following signature:

   The ?get-session? signal

   GstElement*
   user_function (GstRtpBin *rtpbin,
                  guint      id,
                  gpointer   user_data)

The id being the name number as found on the pad you have requested (usually 0,
1, ...).

   g_signal_emit_by_name (rtpbin, "get-sesssion", id, &rtpsession);

What I meant by two pipelines is to use an appsink in the capture pipeline. And
then have you application pass the buffers to the "recording" pipeline through
an appsrc element. Optionally, intervideosink/src might do the job for you.

Re: Gstreamer is not working (Windows)

Here is the code that determines the location of the registry folder (I think): https://gitlab.freedesktop.org/gstreamer/gstreamer/-/blob/master/gst/gstregistry.c#L1733

One possible workaround is to define your own environment variable GST_REGISTRY and point it to a folder that you create on your own system. (See if that fixes the problem.)

FWIW: The function g_get_user_cache_dir() is one of those functions that is difficult to predict on Windows ... and I wish the glib maintainers would find a better behavior for Windows.
