    DNxHD Decoding Issue

    Hello, We use Avid's DNxHR library for decoding of DNxHD/R content. We have occasionally observed that API DNX_CreateDecoder fails with following error "HDCODEC ERROR initialization Failed". On re-running the same file again, this error is not encountered. Can you provide more insights? Is this API thread safe? Regards

    Hello,

    DNxSDK API is not thread safe.

    You can use:

    •     one codec instance with multiple threads per instance if you are interested in min latency
    •     multiple instances with resonable number of threads per instance to achive max throughtput


    If you want to share one codec instance between multiple threads in your application, you should implement safe access to shared resource yourself.


    Thanks,

    Viktor
