Distributed Codec Engine (DCE) is an API and its implementation as software library ("libdce") by Texas Instruments. The library was released under the Revised BSD License and some additional terms.

It enables and provides remote access to hardware acceleration for audio and video decoding on the IVA-HD in OMAP4-based platforms via a syslink/rcm shim layer accessing the OMAP's Codec Engine API codec interface on the co-processor (Ducati/M3) from the host under Linux without needing OpenMAX.[1][2][3] The "Ducati Sub System" comprises two ARM Cortex-M3 processors (CPUs), and the ASICs IVA-HD and ISS.[4]

Software supporting DCE

  • gst-ducati, a GStreamer plugin for OMAP4 using libdce[2][5]
  • omapfbplay, a video player for OMAP using Video4Linux (V4L)[6]

License

It uses a custom vanity license. It does not use an established free open source software license.
