This was produced by selecting "properties" on the select source config page. I was trying to setup the webcamXP IP directshow filter when this came up. The video then froze. Hope this helps.

I also experienced a lot of crashes with it today. The driver seems to keep a record of previously entered addresses and it somehow fallback to old addresses for some reasons.

It would appear that when the address is not reacheable or errors out, crashes occur almost instantly. It becomes very hard to do anything when this driver is the first tried sad
The code needs to be made more robust in this area so it is at least possible to change the source !

Yes, I agree. I also noted that the video would sometimes freeze when switching between different capture sources. However, a fresh restart of the program fixed this issue.

Nonetheless, this is going in the right direction.

Addit: I seem to be also experiencing many more crashes/force close in this new version. For example, when running Kinovea and Firefox together, if Kinovea crashes so too does firefox. I'm not sure if these events are related.
