I think you forgot the last part:
(gdb) bt [...paste the following outputet] (gdb) quit
IOhannes wants to see a full backtrace. it should look like this: https://ftp.gnu.org/old-gnu/Manuals/gdb/html_node/gdb_42.html Christof

Iohannes, managed to make a crash, check the gdb log in the attachment. Basically there is a Segmentation Fault. What does it mean and how can I fix it?

The other problem is that can not identify within pd the cameras. Anything I send to pix_video, fails. I called the cams test1 and test2, however [device test1( does not work, therefor enumerate as well or enumProp.

It says that a valid device is needed, but f I have an image from the camera at startup the patch, why I cannot enumerate it.
you need a valid device for [enumProps(, but not for [enumerate(. you need to hook something like a [print] to the 2nd outlet of [pix_video] in order to get anything meaningful from these messages.
unfortunately did not understand your gdb or microsleep select advices. please specify
Pd prints an error like "microsleep select: Interrupted system call" on the console before it hangs here. does something similar happen?
about gdb, something like this should do the trick (i'm sure i've posted this before):
$ gdb --args pd -nrt -stderr -lib /path/to/Gen /path/to/pix_video-help.pd
[...]
(gdb) thread apply all bt
(gdb) run
[...make it crash...]
