I am sorry that I don't have a solution to your problem, but I was wondering how you went about modifying the build system so that it recognizes your codec? As you know, the build system is largely automated (automatically generates files used during the make). Are you compiling all of the Android code, or just OpenCore? I had the impression that new codecs (or parsers and recognizers in my case) could be added as new directories that the build system would recognize and incorporate into the overall system build. Could you provide me some pointers or steps you went through to add your codec to the system?
