WebRTC API's RTCRtpCodecCapability dictionary provides information describing the capabilities of a single media codec .

特性

channels 可选

An unsigned integer value indicating the maximum number of channels supported by the codec; for example, a codec that supports only mono sound would have a value of 1; stereo codecs would have a 2, etc.

clockRate

An unsigned long integer specifying the codec's clock rate in Hertz (Hz). The IANA maintains a list of codecs and their parameters , including their clock rates.

mimeType

DOMString indicating the codec's MIME media type and subtype. See Codecs used by WebRTC for details about potential codecs that might be referenced here.

sdpFmtpLine 可选

DOMString giving the format specific parameters field from the a=fmtp line in the SDP which corresponds to the codec, if such a line exists. If there is no parameters field, this property is left out.

描述

RTCRtpCodecCapabilities describes the basic parameters for a single codec supported by the user's device. An array of objects of this type is returned in the codecs 特性为 RTCRtpCapabilities object returned in response to a call to either of the static functions RTCRtpSender.getCapabilities() or RTCRtpReceiver.getCapabilities() .

范例
