we are currently working on features that will provide more convenient features in Python.
E.g. supporting an UI integration, which is already possible today but would be to much for a tutorial.
Callbacks fired when the contend of a ring buffer image change, are also an upcoming feature.
What is possible (but undocumented) is accessing individual ring buffer images.
The ring buffer has many features of a standard python list.
Please note, that this is only reasonable if lock mode is on (set to cvb.RingBufferLockMode.On).
imageNr3 = device.stream.ring_buffer
for ring_buffer image in device.stream.ring_buffer:
Finally unlocking a ring buffer image (again lock mode must be on) is done by releasing the image.
del or via python
with device.stream.ring_buffer as imageNr3:
