It's documented here, https://gstreamer.freedesktop.org/releases/1.14/

One to note is in 1.14.2, "v4l2bufferpool: Only return eos for M2M
devices not v4l2src when buggy driver sends empty buffer". That seems
like plausibly your case, some code made for decoders ended up causing
the source thread to stop silently.
