Variable Documentation

COMPATIBLE_BITRATE

const int agora::rtc::COMPATIBLE_BITRATE = -1

-1: Compatible bitrate mode.

In this mode, the bitrate remains the same regardless of the channel profile. If you choose this mode in the live-broadcast profile, the video frame rate may be lower than the set value.

DEFAULT_CONNECTION_ID

const unsigned int agora::rtc::DEFAULT_CONNECTION_ID = 0

static

DUMMY_CONNECTION_ID

const unsigned int agora::rtc::DUMMY_CONNECTION_ID = (std::numeric_limits<unsigned int>::max)()

static

STANDARD_BITRATE

const int agora::rtc::STANDARD_BITRATE = 0

(Recommended) 0: Standard bitrate mode.

In this mode, the bitrates differ between the live broadcast and communication profiles:

• Communication profile: The video bitrate is the same as the base bitrate.
• Live Broadcast profile: The video bitrate is twice the base bitrate.
