<p>The conversion for PCM formats is straight-forward. For non-PCM formats, if there is a fixed size-time conversion (i.e. all IEC61937-encapsulated formats), a "fake" sample spec whose size-time conversion corresponds to this format is provided and the channel map argument is ignored. For formats with variable size-time conversion, this function will fail. Returns a negative integer if conversion failed and 0 on success.</p>
