// Helper methods to create RtpParameters to use for sending/receiving.
//
// "MakeMinimal" methods contain the minimal necessary information for an
// RtpSender or RtpReceiver to function. The "MakeFull" methods are the
// opposite, and include all features that would normally be offered by a
// PeerConnection, and in some cases additional ones.
//
// These methods are intended to be used for end-to-end testing (such as in
// ortcfactory_integrationtest.cc), or unit testing that doesn't care about the
// specific contents of the parameters. Tests should NOT assume that these
// methods will not change; tests that are testing that a specific value in the
// parameters is applied properly should construct the parameters in the test
// itself.
