Maybe somewhat related to https://github.com/JohnDMcMaster/gst-plugin-toupcam/issues/28

Looks like its a race condition related to the pipeline not having a sink. it can be fixed by doing something more like this:

gst-launch-1.0 toupcamsrc num-buffers=1 ! fakesink
GST_PLUGIN_PATH=$PWD/src/.libs/ gst-launch-1.0 toupcamsrc ! videoconvert ! jpegenc snapshot=true ! fakesink

Will close once I verify this a bit more
