    Default Amazon cg1.4xlarge transcoding

    Hello Team,

    I have some trouble with Wowza 3 + Transcode Addon on Amazon EC2 instance. There is Windows x64 OS with CUDA graphic card NVIDIA Tesla 2050 (cg1.4xlarge instance).
    Source stream is rtpm with h264 codec. I`ve enabled transcoder into Application.xml file. Streamtype is live. I use transrate.xml template:

    <Encode>
    <Enable>true</Enable>
    <Name>360p</Name>
    <StreamName>mp4:${SourceStreamName}_360p</StreamName>
    <Video>
    <!-- H.264, PassThru -->
    <Codec>H.264</Codec>

    Looks okay. Did you test with Wowza LiveVideoStreaming player?

    Server: rtmp://[wowza-address]:1935/app
    Stream: myStream_360p

    Hello rrlanham. Thanks for quick response.
    I tested with LiveVideoStreaming player. Source stream downloaded, transcoded stream without CUDA too.
    If I set CUDA transcoder steam didn`t transmit to my browser

    What version of Wowza are you using? If not already, update to latest patch:
    http://www.wowza.com/forums/content....lopment-Builds

    And make sure you have the latest CUDA drivers:

    See if that fixes it. Otherwise let us know.

    Hello Alex, our QA team is going to look at this and we arewondering if you would mind opening a ticket by emailing support@wowza.com and referencing this forum thread. We would like to get access to your Application.xml and the transcoder template you are using and a ticket would be the better place to post them. Thanks for your help.

    Cheers, Adam...

    By any chance was a ticket created on this? I am testing the transcoder addon with this Amazone Ec2 instace and running into the same problem only when CUDA is enabled. When it is turned off and encoding with standard settings everything is fine.

    Our engineering team has confirmed that there is an issue with CUDA acceleration on the cg1.4xlarge; unfortunately, we do not have a short term fix at this time

    ... but there is a trick, you can just reboot the machine once and it should work.
