== Introduction ==
The OMAP3530 includes a built-in TMS320C64X+ DSP Core that provides advanced hardware acceleration support for media encoding / decoding.<br>
For further details, refer to the [http://focus.ti.com/general/docs/litabsmultiplefilelist.tsp?literatureNumber=spruf98d OMAP35x Technical Reference Manual].

== Windows CE Media Codec Framework ==
The OMAP35x Media Codec Framework for Windows CE is comprised of a set of software components integrated into the operating system environment:
# '''DirectShow Filter''' - Direct Show is the standard media streaming architecture within the Windows CE operating system.
# '''Codec Engine''' - Codec Engine is a framework for creation and interaction with multimedia codecs, running either locally or on another processor (DSP).

DSP codecs (i.e. the ones in the DSP server/combo) can be utilized through the DirectShow framework in Windows Media Player.

== Creating Videos ==
The DirectShow video application framework currently supports accelerated MPEG4, MPEG2, H.264 and MP3 wrapped in an AVI container with video quality up to D1 (720x480p @ 30 fps).

The framework also supports WMV content playback. WMV hardware acceleration is not implemented, therefore only videos of up to 640x480 @ 15 fps are supported.

Example video clips can be downloaded from [http://www.apple.com/trailers Apple trailers]. Use Quicktime Pro to download and save the trailer videos. Apple trailer videos must be converted for compatibility with Windows CE media player. Use the [http://www.erightsoft.com/SUPER.html Super] conversion tool.

The tables below provide sample Super configuration settings for video conversion.
