How to add custom codec to EZSDK5.02/OpenMax

ethan lyle

I am familiar with DVSDK3.0. It has a codec server/codec engine/dmai/application achitechture

when add custom codec which compliant to xdm, the step is to change codec server/ dmai/ application.

regard EZSDK/OpenMax framework, it seems easy to use codecs ti has contains,

but how to add custom codec?

I can't find codec server and don't know much about OpenMax framework

You may use the following wiki as a starting point for becoming familar with OMX

The MP3 decode application example can be found

/ti-ezsdk_dm814x-evm_5_02_02_60/component-sources/omx_05_02_00_14/packages/ti/omx/demos/adec_snt

The MP3 decoder can be used as a template for creating a custom codec

/ti-ezsdk_dm814x-evm_5_02_02_60/component-sources/omx_05_02_00_14/packages/ti/omx/comp/adec

Also add an entry to the OMX component list, DomxCore_componentCoreInfoTblEntries, exactly the way AUDDEC is done

See

/ti-ezsdk_dm814x-evm_5_02_02_60/component-sources/omx_05_02_00_14/packages/ti/omx/domx/domx_cfg.c and dom_cfg.h
