This one is strange to me.

Should be part of gst-plugins-base package. You can verify if you have
it by running: `gst-inspect-1.0 appsrc`

They are optional from --enable-gstvideo. Lack of plugins generate a
warning after the autogen.sh but it still let you build the code.

AFAIK, in case the gstreamer pipeline does not work, it should fallback
to default mjpeg decoder.

check what is used there.
