Generating VP8 fmtp parameters
Project Member Reported by, Oct 10 2013 Back to list specifies that the size parameters max-fr and max-fs are REQUIRED in an SDP description.

The implementations need to generate sensible values for the platform they're running on.

Assigning tentatively to Peter for now.
To help us move forward with this bug: Is it more important that we generate these values or that these values are honored by the system?

It'd also be helpful to elaborate on "sensible values" here.

The state we want to get to is that the receiver always sets the parameters, and the sender always respects them.

Case analysis:

- Receiver doesn't sent, sender doesn't respect: Current situation. Sender sends whatever it wants.
- Receiver sets, sender does not respect: Worse than current - formally noncompliant, receivers written in expectation of respected limits will be overrun.
- Receiver does not set, sender respects: Sender sends what it wants. No worse than current situation.
- Receiver sets, sender respects: Good.

From this analysis, the first implementation should be sender respecting the parameters. It's OK to make our receiver send some hardcoded values (HD@30?) as a first implementation - then we can change them (up or down depending on platform) afterwards.

This looks like it's not hitting m42.  Update it if I'm wrong.

I don't see any CLs linked to this bug, so I don't think it's been fixed. Removing milestone label since this bug hasn't been updated in quite some time.
