Dear Simon,
after having read the description of what you want to do, I thought about another solution. We are currently working at an iOS implementation of the 3D Tune-In Toolkit. It's an HRTF-based binaural spatialisation engine, so not an HOA-to-binaural converter, but...if you decode the HOA stream to an array of loudspeakers and then render each of them as an individual source in the binaural spatialiser, it will work. It currently works on an iPad Pro 2, and it can handle 25-30 anechoic sources at the same time (without binaural reverberation so...anechoic spatialisation). The head tracking is done using the sensors on the phone/tablet, and each source can be played/stopped remotely via OSC. All sources positions can be imported in the application through a configuration file (json), while the sound files need to be located in the mobile device (but you can also read them from Dropbox or other online storage). It's just a prototype at the moment, but it works already very well. The iPad Pro 2 is a rather powerful machine, but current iPhones and iPads will do even better. So...in this case, you'll just need to synchronise the OSC play/stop with the video, and it will play remotely on every user's device. If interested, let me know and we'll find a way for you to try it (TestFlight or similar).
