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.

Thanks for you help,

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

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

#4

If you have not already try the latest patch:

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.

#5

Try updating to latest Sun JDK.

http://www.oracle.com/technetwork/java/javase/downloads/index.html

And apply latest patch

Michal, try adding the following to all Encode/Parameter blocks in your transcoder XML file:

mainconcept.cpu_opt

Integer

I have not tuned the server because it is a development system.

Does only work with Red hat? I know programs compiled on red hat is not compatible with other system with out patches.

It works on Centos 6.0 vm but not on a openSUSE 11.4

Our tests previously went on well with the following configuration:

  1. Dell R210 server (Intel Xeon CPU X3430 @ 2.40GHz) having Ubuntu Server 11.10, Java version OpenJDK 20.0-B11 [OK]

but now with:

  1. Asus P8Z68-Vpro v3.0 (Intel Core i7-2600K CPU @ 3.40GHz) having Ubuntu Server 11.10, Java version OpenJDK 20.0-B11 [FAILED]

  2. Asus P8Z68-Vpro v3.0 (Intel Core i7-2600K CPU @ 3.40GHz) having Ubuntu Server 11.10, Java version Sun 6.0_26-b03 [FAILED]

All failures came with input of Multicast Mpeg TS stream + transcoding to H.264 + audio mp3

Any help would be appreciated. Today we contacted Sun with the errorcodes, sofar no reply yet.
