buffer v4l2src for 30 seconds

Your problem is that the v4l2src is defaulting to mmap mode, which has a
limitation on the amount of buffers that can be mapped. In most
applications this is not a problem but when you are buffering memory like
that you will hit the limit (32 frames according to videodev2).
You can work around this with 2 ways:
a) Copy the frames before they enter the queue. you can do this using a
probe.
b) Set the "io-mode" to one that is not limited in the size of memory it
can allocate. This one depends on the device you are connecting to and what
it supports.
for example, this works for me:
gst-launch-1.0 v4l2src io-mode=3 ! queue min-threshold-time=10000000000
max-size-time=100000000000 max-size-buffers=0 max-size-bytes=0 !
videoconvert ! ximagesink --gst-debug=v4l2src:6
rw is also an option for an "unlimited" amount of memory, although it is
suboptimal since it causes additional memory copies. If you are stuck with
mmap you can post here again and work on getting a probe running in an app
