The WebRTC API's RTCRtpSendParameters
dictionary is used to specify the parameters for an RTCRtpSender
when calling its setParameters()
method.
RTCRtpSendParameters
Properties
In addition to the properties below, RTCRtpSendParameters
inherits the properties from the RTCRtpParameters
interface.
-
encodings
-
An array of
RTCRtpEncodingParameters
objects, each specifying the parameters for a single codec that could be used to encode the track's media. -
transactionId
-
A string containing a unique ID for the last set of parameters applied; this value is used to ensure that
setParameters()
can only be called to alter changes made by a specific previous call togetParameters()
. Once this parameter is initially set, it cannot be changed.
Obsolete properties
