[M4IF Technotes] Distortion Testing for Encoder

[Rob Koenen]

Indeed, any decoder that produces a valid bistream is compliant
to the standard. There are deliberately no prescribed quality 
metrics, nor is there any prescribed algorithm to perform the
encoding.
This means there will be good encoders and bad ones...
Best,
Rob
