setBitrate
@CanIgnoreReturnValue
fun setBitrate(bitrate: Int): VideoEncoderSettings.Builder!
Sets bitrate. The default value is NO_VALUE.
| Returns | |
|---|---|
VideoEncoderSettings.Builder! |
This builder. |
setBitrateMode
@CanIgnoreReturnValue
fun setBitrateMode(@VideoEncoderSettings.BitrateMode bitrateMode: Int): VideoEncoderSettings.Builder!
Sets bitrateMode. The default value is
MediaCodecInfo.EncoderCapabilities.BITRATE_MODE_VBR.
Value must be in BitrateMode.
| Parameters | |
|---|---|
@VideoEncoderSettings.BitrateMode bitrateMode: Int |
The |
| Returns | |
|---|---|
VideoEncoderSettings.Builder! |
This builder. |
setEncoderPerformanceParameters
@CanIgnoreReturnValue
fun setEncoderPerformanceParameters(operatingRate: Int, priority: Int): VideoEncoderSettings.Builder!
Sets encoding operating rate and priority. The default values are NO_VALUE, which is treated as configuring the encoder for maximum throughput.
To disable the configuration for either operating rate or priority, use RATE_UNSET for that argument.
| Parameters | |
|---|---|
operatingRate: Int |
The |
priority: Int |
The |
| Returns | |
|---|---|
VideoEncoderSettings.Builder! |
This builder. |
setEncodingProfileLevel
@CanIgnoreReturnValue
fun setEncodingProfileLevel(encodingProfile: Int, encodingLevel: Int): VideoEncoderSettings.Builder!
Sets profile and level. The default values are both NO_VALUE.
The value must be one of the values defined in MediaCodecInfo.CodecProfileLevel, or NO_VALUE.
Profile settings will be ignored when using DefaultEncoderFactory and encoding to H264.
| Returns | |
|---|---|
VideoEncoderSettings.Builder! |
This builder. |
setMaxBFrames
@CanIgnoreReturnValue
fun setMaxBFrames(maxBFrames: Int): VideoEncoderSettings.Builder!
Sets the maximum number of B frames allowed between I or P frames in the produced video. The default value is NO_VALUE which means that B frame encoding is disabled.
| Parameters | |
|---|---|
maxBFrames: Int |
the |
| Returns | |
|---|---|
VideoEncoderSettings.Builder! |
This builder. |
setRepeatPreviousFrameIntervalUs
@CanIgnoreReturnValue
fun setRepeatPreviousFrameIntervalUs(repeatPreviousFrameIntervalUs: Long): VideoEncoderSettings.Builder!
Sets the threshold duration between input frames beyond which to repeat the previous frame if no new frame has been received, in microseconds. The default value is NO_VALUE, which means that frames are not automatically repeated.
| Parameters | |
|---|---|
repeatPreviousFrameIntervalUs: Long |
The |
| Returns | |
|---|---|
VideoEncoderSettings.Builder! |
This builder. |
setTemporalLayers
@CanIgnoreReturnValue
fun setTemporalLayers(
numNonBidirectionalLayers: Int,
numBidirectionalLayers: Int
): VideoEncoderSettings.Builder!
Sets the number of temporal layers to request from the video encoder.
The default value for both parameters is NO_VALUE which indicates that no temporal layering schema will be set for the encoder.
| Parameters | |
|---|---|
numNonBidirectionalLayers: Int |
the number of predictive layers to have. This value must be stricly positive. A value of '0' explicitly requests no temporal layers from the encoder, regardless of the requested 'numBidirectionalLayers'. |
numBidirectionalLayers: Int |
the number of bi-directional layers to have. This value must be greater than or equal to zero. A value greater than 1 constructs a hierarchical-B coding structure. |
| Returns | |
|---|---|
VideoEncoderSettings.Builder! |
This builder. |
setiFrameIntervalSeconds
@CanIgnoreReturnValue
fun setiFrameIntervalSeconds(iFrameIntervalSeconds: Float): VideoEncoderSettings.Builder!
Sets iFrameIntervalSeconds. The default value is DEFAULT_I_FRAME_INTERVAL_SECONDS.
| Parameters | |
|---|---|
iFrameIntervalSeconds: Float |
| Returns | |
|---|---|
VideoEncoderSettings.Builder! |
