#158 closed defect (fixed)
Current driver crashes with segmentation fault when recording with GUI
| Reported by: | Matthias Vogelgesang | Owned by: | Matthias Vogelgesang |

| Component: | libuca | Version: | |

Description
Steps to reproduce
- Login to
ipecamera - Run
control - Press record button
- Stop recording
Behaviour
Everything crashes with a segmentation fault. A quick look with gdb suggests that the last frame is corrupt and cannot be decoded properly with libufodecode. When using a debug build of libufodecode, recording does not crash that often.
This behaviour must have been introduced with the recent changes to the driver as this was not a problem last Friday.

I made a temporary fix in the /root/libuca, but probably it should be properly fixed with mutexes.

- Could we please agree on one place to checkout all the sources?
- Could you please document such pitfalls?
- Your temporary fix is duplicating all the work that is already done in the base class (including proper synchronisation with mutexes) and breaking streaming fast-reject.
