I must be missing something here. Why would this media controller API make things simpler? Based on what was presented at LPC, I don't understand this last part.
It'd make the tie up with algorithms part much easier as we could have an interface for transferring the compressed data alone and then externally describe how that's plumbed into any other DSP that's going on and the physical outputs - it'd help with treating the data transfer as a standalone problem.
Still not convinced. Why would you need to 'externally describe' how compressed data is linked to post-processing. It's all part of DSP firmware, why should anyone care how the decoder provides data to post-processes? You can control post-processes with ALSA controls as for regular PCM.
