The most significant one, as I mentioned in my previous post, is GPU-accelerated H.264 encoding. It is powered by NVIDIA CUDA technology via the MainConcept H.264 CUDA SDK. The Expression Encoder team has put together an excellent white paper describing the new feature and best practices. A separate report will be published later this week with performance data and comparisons of recommended PC configurations.

Update (1/27/2011): An interesting note about the H.264 GPU acceleration feature:  When using the EE4 GUI application, GPU-accelerated H.264 encoding will be enabled by default (assuming your hardware is CUDA 1.1 compatible) unless you decide to disable it via the Tools|Options configuration dialog. However, when using the EE4 SDK, GPU acceleration will be disabled by default, meaning that any apps that you built on the EE4 SDK will need to be recompiled with the GPU acceleration option explicitly enabled if you want to take advantage of the new feature. Otherwise they will just default to the old CPU-based H.264 encoding method.

    Great news!!

    Alex, in this service pack will be available one option for “auto reconnect” on Smooth Streaming? Every time we need to shutdown and restart the publishing point, it’s very inconvenient. Thanks
