No such element or plugin 'viperfx' #4

Closed jeffshee closed 4 years ago

jeffshee commented 4 years ago

Hi, thanks for maintaining this project =) For some reason, the plugin doesn't work for me. I'm using Fedora 32.

Compile seems ok, except there is 1 warning. Could it be the reason? P/S: I had copied the .so file to both /usr/lib/gstreamer-1.0 and /usr/lib64/gstreamer-1.0, just in case.

@ThePBone want to take this?

timschneeb commented 4 years ago

It seems like everything compiled successfully, you can ignore the warning there's no way it could break anything.

Could you run gst-inspect-1.0 viperfx and check if it detects the plugin? If it doesn't find the plugin in the registry it may have been blacklisted, you can check that with: gst-inspect-1.0 -b.

If the plugin is neither blacklisted nor found in the registry at all, you might need to specify the plugin path manually. According to the docs, you can do that adding an environmental variable: export GST_PLUGIN_PATH=/usr/lib64/gstreamer-1.0

Thanks for reply.

Ok, I think I know what is the mistake here... Apparently, I have anaconda installed in my system, and it turns out that the anaconda's binary is preferred over the system binary for some reason...

 ❯ which gst-inspect-1.0                                                                                    [15:17:16]
~/anaconda3/bin/gst-inspect-1.0

With the explicit binary path specified, it seems the plugin is actually recognized successfully.

❯ /bin/gst-inspect-1.0 viperfx                                                                             [15:19:33]

Plugin Details:
  Name                     viperfx
  Description              viperfx element
  Filename                 /usr/lib64/gstreamer-1.0/libgstviperfx.so
  Version                  2.0.0
  License                  Proprietary
  Source module            viperfx-plugin
  Binary package           GStreamer
  Origin URL               http://gstreamer.net/

If the plugin is somehow blacklisted, I found that it is helpful to remove the registry cache. rm ~/.cache/gstreamer-1.0/registry.x86_64.bin

Thanks, I will close the issue as it is solved. Thanks for helping!
