Ok, that is interesting. So if you run it a second time on 1.2, do you get
"flags 00002041" (the 4 means the buffer is corrupted) ?

What I'm working on is a way to conceal the corrupted buffer and keep going.
What I'm thinking though, is that we get corrupted buffer in 1.4 because the
queue is smaller (2 buffers instead of 4 on 1.2). Is this your own build ?

If so, could you change GST_V4L2_MIN_BUFFERS to 4 instead of 2 and retest ? If
so, I'll probably go back to default of 4 buffers (for v4l2src) along with code
to not fail when buffer is corrupted.

p.s. sys/v4l2/gstv4l2object.h:41:#define GST_V4L2_MIN_BUFFERS 2
