Switching DSP Server from Remote to Local

A quick clarification of terms - a 'Server' is only used when your codecs/algs are 'remote'.  If you want to configure your codecs to be on the same processor as the app (i.e., local), you don't need a Server.  This is kind of like using a 'Web Server' if your files are "somewhere else" (e.g. 'remote').  If you move those files locally, you no longer need a Server to access those files.

To change the location of your codecs, you need to modify the configuration of the app's "Engine" (an Engine is a collection of codecs that can be used concurrently).  This is done in the app's cfg script.  When codecs are remote, you typically create/configure your Engine with Engine.createFromServer() function - a utility fxn which creates and initializes an Engine with all the codecs in a given Server.  When you don't have a Server, you create your Engine with Engine.create() rather than Engine.createFromServer().

Concretely, you probably need to switch from Engine.createFromServer() to Engine.create()... something like this:

var myAlg = xdc.useModule(
    'ti.sdo.ce.examples.codecs.universal_copy.UNIVERSAL_COPY');

var Engine = xdc.useModule('ti.sdo.ce.Engine');
var myEngine = Engine.create("universal_copy" /* engine name */, [
    {
        name : "universal_copy",  /* alg name */
        mod  : myAlg,             /* alg module handle */
        local: true               /* alg is local */
    }
]);

If you look at the CE examples (examples/ti/sdo/ce/examples/apps/*) you'll typically see 2 config scripts - remote.cfg and local.cfg.  These 'move' the codecs from being remote to being local - note that by design, the application doesn't have to change at all(!).

Finally, if you will still have some remote codecs in a Server, and just want to add a few local algs to that Engine.createFromServer()-created Engine, this section article describes how to do that:

Is that symbol something your algorithm library should be supplying?  If so, are you returning your algorithm library in your algorithm package's package.xs::getLibs() function?  (getLibs() is how each package contributes its library(s) to the generated linker command file.)

Maybe posting your package.xs::getLibs() function would help see what's going on?
