Methods

`Optional`processingDidFailToStart

processingDidFailToStart(): void
processingDidFailToStart will be called when VideoFrameProcessorPipeline could not start streaming due to runtime errors.

Returns void
- Defined in src/videoframeprocessor/VideoFrameProcessorPipelineObserver.ts:16

`Optional`processingDidStart

processingDidStart(): void
processingDidStart will be called when VideoFrameProcessorPipeline starts streaming.

Returns void
- Defined in src/videoframeprocessor/VideoFrameProcessorPipelineObserver.ts:11

`Optional`processingDidStop

processingDidStop(): void
processingDidStop will be called when VideoFrameProcessorPipeline stops streaming expectedly.

Returns void
- Defined in src/videoframeprocessor/VideoFrameProcessorPipelineObserver.ts:21

`Optional`processingLatencyTooHigh

processingLatencyTooHigh(latencyMs: number): void
processingLatencyTooHigh will be called when the execution of VideoFrameProcessorPipeline slows the frame rate down by half.
Parameters
- latencyMs: number
Returns void
- Defined in src/videoframeprocessor/VideoFrameProcessorPipelineObserver.ts:26
