I'm having trouble with v4l2src in gstreamer-1.0, but it appears to be there in gstreamer-0.10. I've searched around online but none of the suggestions seems to make any difference. I've included a bunch of results below. Is there anything else I can try?
Update: @alper-kucukkomurler is correct. I have anaconda installed and which gst-inspect-1.0 is returning ~/anaconda2/bin. Removing anaconda from my path does resolve the issue. However, I'd prefer a solution which keeps anaconda in the path if possible. Is there a way to make this work? (I do have gstreamer and gst-plugins-base packages installed in anaconda).
Update2: A tip came from another forum https://forum.openframeworks.cc/t/error-ofgstutils-error-getting-device-data-no-element-v4l2src/26908/6
pointing to this post GStreamer plugin search path?
discussing GST_PLUGIN_PATH. I actually don't have such an env variable. But it is an additional point of info.
