nanoAVC/H.264 DirectShow Decoding SDK​

Introduction​

nanoAVC/H.264 Direct Show Decoding SDK enables you to decode/play back AVC/H.264 video and AAC audio from MP4/3GP or transport stream (TS) sources within Windows Media Player and custom applications based on Microsoft DirectShow Framework.

The nanocosmos H.264/AVC Video Decoder supports streams in baseline, main and high profile. It is highly optimized for use on hyper-threading and multi core systems.

Registering and unregistering components in the DirectShow framework​

In order to use them, filters must be registered in the DirectShow framework. After installation all filters are registered. To re-register or unregister components, execute the RegisterFilters.bat or UnregisterFilters.bat batch files from the SDK/bin folder.

Evaluation mode and filter activation​

Filters can be activated by installing a license key to windows registry or programmatically by setting a license key through the software interface of a filter instance. How to set license keys to unlock filters is described in the module's documents.\ If filters run in evaluation mode, an overlay logo will be shown on video.

Embedding / Customizing nanocosmos technology​

Nanocosmos also offers special OEM and customization service. Dependent on your needs, we may offer different models of licensing or application development.
