This looks strange that this message shows up at the second call and not
at the first one. You should try again in a fresh environment. Sorry not
to be more helpful...

Hi,
I am using Python 2.7.6
Camera is able to fetch the first frame. Camera hangs when I attempt to fetch a second frame.
The camera I am using is VT-Nep1600-50gm
Camera is hanging at the line buffer = stream.pop_buffer() in the second call to it.
Thank you

It seems to me this is related to your python environment. When I
add the statement
data = buffer.get_data()
after
buffer = stream.pop_buffer()
in the arv-camera-test.py example, I do not get any error message.
I use Python 2.7.9 on a Raspberry Pi 2 with Linux 4.1.15-v7+ #830.
What is the version of Python you use?

Hi,
I have installed Aravis and I can run arv-camera-test.py
successfully.
But when I try to fetch data from buffer by
data = buffer.get_data()
I am getting the error
"Data access methods are unsupported. Use normal Python
attributes instead".
Can someone throw light on, what is the cause and how I can
move forward.
Thank you
