RTCRtpEncodingParameters.maxBitrate - Web APIs 编辑

The RTCRtpEncodingParameters dictionary's maxBitrate property specifies the maximum number of bits per second to allow a track encoded with this encoding to use.

Syntax

rtpEncodingParameters.maxBitrate = maxBitsPerSecond;

rtpEncodingParameters = {
  maxBitrate: maxBitsPerSecond
};

maxBitsPerSecond = rtpEncodingParameters.maxBitrate;

Value

An unsigned long integer value specifying the maximum bandwidth this encoding is permitted to use for a track of media it encodes in terms of bits per second. Other parameters may further reduce the bandwidth used by the track; for example, maxFramerate will, if set low enough, constrain the bandwidth as well.

In addition, there's no guarantee that the network interface can support the specified bandwidth, in which case the actual bandwidth will be lower.

This value is computed using the standard Transport Independent Application Specific Maximum (TIAS) bandwidth as defined by RFC 3890, section 6.2.2; this is the maximum bandwidth needed without considering protocol overheads from IP, TCP or UDP, and so forth.
