v4l2src doesn't launch always - seems to be a clock issue

Hi all,

With regards to earlier post about v4l2src, we have narrowed down the
problem to one set of logs.

Going through the logs, I am finding this DEBUG message keeps repeating
when the pipeline stream* isn't playing.*

0:00:18.777042366  1895 0xaaaafba09600 DEBUG               basesink
gstbasesink.c:5408:default_element_query:<autovideosink0-actual-sink-wayland>
position query in format time
0:00:18.777067992  1895 0xaaaafba09600 DEBUG               basesink
gstbasesink.c:5342:gst_base_sink_get_position:<autovideosink0-actual-sink-wayland>
*position in wrong state, return -1*



When the pipeline is working properly, I get the following message, instead

0:00:13.244891490  1917 0xaaab01cec600 DEBUG               basesink
gstbasesink.c:5408:default_element_query:<autovideosink0-actual-sink-wayland>
position query in format time
0:00:13.244928990  1917 0xaaab01cec600 DEBUG               basesink
gstbasesink.c:5200:gst_base_sink_get_position:<autovideosink0-actual-sink-wayland>
using clock and base time 0:41:42.435970707



Can anyone comment on what this error might mean ?  Seems like the stream
is not able to initialize the clock for some reason ?
