Video encoder configurations.
int agora::rtc::VideoEncoderConfiguration::bitrate |
The video encoding bitrate (Kbps).
Choose one of the following options:
- STANDARD_BITRATE: (Recommended) The standard bitrate.
- The Communication profile: the encoding bitrate equals the base bitrate.
- The Live-broadcast profile: the encoding bitrate is twice the base bitrate.
- COMPATIBLE_BITRATE: The compatible bitrate: the bitrate stays the same regardless of the profile.
The Communication profile prioritizes smoothness, while the Live-broadcast profile prioritizes video quality (requiring a higher bitrate). We recommend setting the bitrate mode as STANDARD_BITRATE to address this difference.
The following table lists the recommended video encoder configurations, where the base bitrate applies to the Communication profile. Set your bitrate based on this table. If you set a bitrate beyond the proper range, the SDK automatically sets it to within the range.
