Our Wowza server crashed randomly. Looking at the logs, it appears to be related to the real-time transcoder. Both the error.log and access.log have this final entry and then it crashed:

TranscoderWorkerVideoDecoder.setupDecoder: Error videoDecoderCreate: 4294967295

Can you please assist? Here are the last error logs.

Sorry I should have posted this on the 3.x forum. Please let me know either way what the root cause is.
