int agora::rtc::LiveTranscoding::width |
The width of the video in pixels. The default value is 360.
width
is [64,1920]. If the value is less than 64, Agora server automatically adjusts it to 64; if the value is greater than 1920, Agora server automatically adjusts it to 1920.width
and height
as 0. int agora::rtc::LiveTranscoding::height |
The height of the video in pixels. The default value is 640.
height
is [64,1080]. If the value is less than 64, Agora server automatically adjusts it to 64; if the value is greater than 1080, Agora server automatically adjusts it to 1080.width
and height
as 0. int agora::rtc::LiveTranscoding::videoBitrate |
Bitrate of the CDN live output video stream. The default value is 400 Kbps.
Set this parameter according to the Video Bitrate Table. If you set a bitrate beyond the proper range, the SDK automatically adapts it to a value within the range.
int agora::rtc::LiveTranscoding::videoFramerate |
Frame rate of the output video stream set for the CDN live streaming. The default value is 15 fps, and the value range is (0,30].
bool agora::rtc::LiveTranscoding::lowLatency |
int agora::rtc::LiveTranscoding::videoGop |
Video GOP in frames. The default value is 30 fps.
VIDEO_CODEC_PROFILE_TYPE agora::rtc::LiveTranscoding::videoCodecProfile |
Self-defined video codec profile: VIDEO_CODEC_PROFILE_TYPE.
unsigned int agora::rtc::LiveTranscoding::backgroundColor |
The background color in RGB hex value. Value only. Do not include a preceeding #. For example, 0xFFB6C1 (light pink). The default value is 0x000000 (black).
VIDEO_CODEC_TYPE_FOR_STREAM agora::rtc::LiveTranscoding::videoCodecType |
The video codec type of the output video stream. See VIDEO_CODEC_TYPE_FOR_STREAM.
unsigned int agora::rtc::LiveTranscoding::userCount |
The number of users in the interactive live streaming.
The value range is [0,17].
TranscodingUser* agora::rtc::LiveTranscoding::transcodingUsers |
const char* agora::rtc::LiveTranscoding::transcodingExtraInfo |
Reserved property. Extra user-defined information to send SEI for the H.264/H.265 video stream to the CDN live client. Maximum length: 4096 Bytes.
For more information on SEI frame, see SEI-related questions.
const char* agora::rtc::LiveTranscoding::metadata |
RtcImage* agora::rtc::LiveTranscoding::watermark |
The watermark on the live video. The format must be in the PNG format. See RtcImage. You can add a watermark or use an array to add multiple watermarks. This parameter is used in conjunction with watermarkCount
.
unsigned int agora::rtc::LiveTranscoding::watermarkCount |
The number of watermarks on the live video. The total number of watermarks and background images must be greater than or equal to 0 and less than or equal to 10. This parameter is used in conjunction with watermark
.
RtcImage* agora::rtc::LiveTranscoding::backgroundImage |
The background image on the live video. The format must be in the PNG format. See RtcImage. You can add a background image or use an array to add multiple background images. This parameter is used in conjunction with backgroundImageCount
.
unsigned int agora::rtc::LiveTranscoding::backgroundImageCount |
The number of background images on the live video. The total number of watermarks and background images must be greater than or equal to 0 and less than or equal to 10. This parameter is used in conjunction with backgroundImage
.
AUDIO_SAMPLE_RATE_TYPE agora::rtc::LiveTranscoding::audioSampleRate |
Self-defined audio-sample rate: AUDIO_SAMPLE_RATE_TYPE.
int agora::rtc::LiveTranscoding::audioBitrate |
Bitrate of the CDN live audio output stream. The default value is 48 Kbps, and the highest value is 128.
int agora::rtc::LiveTranscoding::audioChannels |
The numbder of audio channels for the CDN live stream. Agora recommends choosing 1 (mono), or 2 (stereo) audio channels. Special players are required if you choose option 3, 4, or 5:
AUDIO_CODEC_PROFILE_TYPE agora::rtc::LiveTranscoding::audioCodecProfile |
Self-defined audio codec profile: AUDIO_CODEC_PROFILE_TYPE.
LiveStreamAdvancedFeature* agora::rtc::LiveTranscoding::advancedFeatures |
The advanced feature of the RTMP or RTMPS streaming with transcoding. See LiveStreamAdvancedFeature.
unsigned int agora::rtc::LiveTranscoding::advancedFeatureCount |
The number of the enabled advanced feature. The default value is 0.
