Integrate New Codec for DM3xx

If a new codec needs to be added to the standard DVSDK release, both the codec bundle and application need to be modified.

Copy the codecs packages into a temporary directory: ~\temp_audio and extract them
Copy the codecs to the codec bundle (e.g., <codecs_package>\<codec_name>_#_#_##_production_dm365_mvl\packages-production\ittiam to the following location: dvsdk_#_##_##_##\dm365_codecs_#_##_##_##\packages)
Delete the dvsdk_#_##_##_##\dm365_codecs_#_##_##_##\packages\ittiam\app folder. It will not be needed
Make the following configuration file changes:

Add the codec of choice to the configuration file (e.g., audio_decode_io1_dm3xx.cfg file).

In the example below we are modifying audio_decode_io1_dm3xx.cfg to add the MP3 decoder to existing codec AAC decoder

var MP3_DEC  = xdc.useModule('ittiam.codecs.mp3_dec.ce.MP3_DEC');
 
var Engine = xdc.useModule('ti.sdo.ce.Engine');
var myEngine = Engine.create("decode", [
    {name: "aac_dec", mod: AAC_DEC, local: true},
    {name: "mp3_dec", mod: MP3_DEC, local: true},
]);

Add the following lines in the same configuration file to set the cache enabling feature of CE for ARM-side algorithms (Please see codec_engine documentation for the details)

MP3_DEC.useCache = true;
