Re: [webrtc-pc] sdpFmtpLine isn't very convenient

@taylor-b  I have some more basic questions:

a. What is returned by sender.getParameters().codecs[].sdpFmtpLine?  
Is this supposed to represent settings relating to the sender, or 
capabilities of the sender as reflected in the Offer or Answer?  

For example, if the remote peer offers profile-level-id=42c02a 
(indicating the maximum it can receive), does the sender's sdpFmtpLine
 include profile-level-id=42c02a, reflecting what was offered by the 
remote peer (since that constrains the sender)?  Or is it not present 
at all since profile-level-id represents a receiver capability and we 
called sender.getParameters()?

b. Same question for receiver.getParameters().codecs[].sdpFmtpLine

c. Can sdpFmtpLine be modified by sender.setParameters()?  If 
sdpFmtpLine represents what is in the Offer or Answer, the answer 
should probably be "no".  But if it represents a sender setting, then 
maybe it can be set?
