Trying to trans code from mpeg2 codec with mpeg2-ts with mp3 audio container to h.264 with mp4 container and the java 6 is getting a fatal error and Woza crashed when it started to set up the trans coder. Also tried with mpeg1/2 audio in mpeg2 file. have you had other people having this problem.

We do not have similar reports. What version are you running? Is the server properly tuned: [https://www.wowza.com/docs/how-to-do-performance-tuning](https://www.wowza.com/docs/how-to-do-performance-tuning) What is the source of the stream. What OS and version of Java. If Java created a stack trace log we would like to see it. The transcoder does not work on all flavors of Linux. What is the exact flavor of Linux and version.

I know that RedHat, Fedora, CentOS, Debian (5.x) and Ubuntu all work. I have not tried all versions but I have tried stable version of all of these. Charlie ---

If you have not already try the latest patch: [https://www.wowza.com/docs/wowza-streaming-engine-software-updates](https://www.wowza.com/docs/wowza-streaming-engine-software-updates) This may not resolve the problem. There is a known issue with the MainConcept libraries on SandyBridge processors on Linux. We are working with MainConcept on a resolution. We do not have a timeframe as to when this will be fixed.
