Remarks
Subscribe to vendor parameters, so that these parameters will be present in #getOutputFormat and changes to these parameters generate output format change event.
Unrecognized parameter names or standard (non-vendor) parameter names will be ignored. #reset also resets the list of subscribed parameters. If a parameter in names is already subscribed, it will remain subscribed.
This method can be called in any codec state except for released state. When called in running state with newly subscribed parameters, it takes effect no later than the processing of the subsequently queued buffer. For the new parameters, the codec will generate output format change event.
Note that any vendor parameters set in a #configure or #setParameters call are automatically subscribed.
See also #INFO_OUTPUT_FORMAT_CHANGED or Callback#onOutputFormatChanged for output format change events.
