Properties

$instance → dynamic

no setter, inherited

encoderPreference ↔ VideoEncoderPreference

@brief Encoding preference. The default value is MaintainFramerate(1). See EncoderPreference{@link #EncoderPreference}.

getter/setter pair

frameRate ↔ int

@brief Video frame rate in fps

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

height ↔ int

@brief Height of the video frame in px

getter/setter pair

maxBitrate ↔ int

@brief Maximum bit rate in kbps. Optional for internal capturing while mandatory for custom capturing.
If you set this value to -1, SDK will automatically calculate the applicable bit rate based on the input resolution and frame rate.
No stream will be encoded and published if you set this value to 0.
In 3.44.1 and later versions, the default value is -1 for internal capturing, but no default value in versions earlier than 3.44.1.

getter/setter pair

minBitrate ↔ int

@brief Minimum video encoding bitrate in kbps. The encoding bitrate will not be lower than the minBitrate.
It defaults to 0.
It ranges within [0, maxBitrate). When maxBitrate < minBitrate, the bitrate is self-adpapted.
In the following circumstance, the assignment to this variable has no effect:
- When maxBitrate = 0, the video encoding is disabled. - When maxBitrate < 0, the bitrate is self-adapted.

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

width ↔ int

@brief Width of the video frame in px

getter/setter pair

inherited

fn2AndroidClass(Function callback, dynamic nativeClass(), String methodName) → dynamic
