IBooks Author crashes every 30 seconds: h264 encoder?

Question

I am using iBooks Author 2.1.1 on Mavericks.
The program is crashing like every 30 seconds for no apparent reason (specific actions, that is). I cannot see the <edited by host> problem reporter anymore  . This is what it offers all the time stating some problem with the h264 encoder framework (please see attached image below). A reinstallation has not helped so far. What can I do here?
Many thanks in advance,
Jan

Answer 1

Did you already try removing iBA's preference plist as part of your troubleshooting process?
I don't think that plugin is the culprit ...perhaps more like an incidental victim in this example.
However, as this is a predicable issue, you may want to get Apple Support on the phone and let them take a look.

As for the <edited by host> problem reporter  , you can see error/crash logs if you know how to use Console in /Applications/Utilities and have the time to weed out related info - Support might ask you to do that, in which case they will inform the process, etc.
Good luck in any case.
