When it comes to sample rate, layer and version switching, I think you're reasonably safe, though it is probably legal. Stereo mode I think you will find encoders may switch from frame to frame.
Is anyone in a position to send me an example file please? Or seond-best, name an encoder with a required set of options.
Difficult to test my app without test data - and quite a chore to manufacture such a file by hand. (...and that bit of the app is not yet written)
