Android Unable to instantiate codec 'video/avc'

4

This is my first post, so bear with me.

I'm trying to play raw h264 video onto a Surface object in an android app. I'm using android 5.0.1 on an HTC one. After reading through the android docs, I've found that I need to use a MediaCodec object to decode the raw bytes and then release them to the Surface. I've poured through tons of other questions and docs, but haven't found an answer to my seemingly very simple problem. Here is a snippet of my code:

        @Override
        public void surfaceCreated(SurfaceHolder surfHolder) {
            try {
                String codecType = "video/avc";
                MediaFormat mf = MediaFormat.createVideoFormat(codecType, 45 ,45);
                mc = MediaCodec.createByCodecName(codecType);
                mc.configure(mf, surfHolder.getSurface(), null, 0);
                mc.setCallback(vcb);
                mc.start();
            }
            catch (Exception e) {
                e.printStackTrace();
            }
        }

However, I am getting stuck when it tries to create the codec by name, and I get this error:

There is tons of information on what to do after the MediaCodec object is instantiated, but basically nothing (from what I can find) on what happens in this scenario. This kinda makes me hopeful that it's just a silly mistake. Does anyone have any idea?

Thanks in advance.
