Automatic update from web-platform-testsUpdate external/wpt/webrtc/RTCRtpParameters* tests. This is in preparation for get/setParameters[1] and RTCRtpTransceiver[2]. Tests are updated to use promise_test and async/await to make them easier to write and to execute sequentially. Tests are updated to set up a call before getParameters() because many parameters are defined as "that has been negotiated". If we want to test what is returned before negotiation we should add that as separate tests. For now, this is necessary for the tests to run on [1][2]. Some tests are removed because they no longer reflect the spec. Because get/setParameters() and RTCRtpTransceiver has not landed yet, the tests are still expected to fail.

- The codecs sequence is populated based on the codecs that have been negotiated
|
|
for sending, and which the user agent is currently capable of sending.
|
|
|
|
If setParameters has removed or reordered codecs, getParameters MUST return
|
|
the shortened/reordered list. However, every time codecs are renegotiated by
|
|
a new offer/answer exchange, the list of codecs MUST be restored to the full
|
|
negotiated set, in the priority order indicated by the remote description,
|
|
in effect discarding the effects of setParameters.
|
|
|
|

|
|
- When using the setParameters method, the codecs sequence from the corresponding
|
|
call to getParameters can be reordered and entries can be removed, but entries
|
|
cannot be added, and the RTCRtpCodecParameters dictionary members cannot be modified.
