Camera: Rework StreamSplitter for camera use cases
- Merge notifyRequestedSurfaces into getBufferLocked, so that during getBufferLocked, the stream splitter gets to know which outputs the current request is on. - Reserve buffer slot in the output queue during getBufferLocked instead of during onFrameAvailable. So if there is no slot/buffer available, no new request is sent to HAL. This aligns with current cameraservice logic. Do not hold the lock while calling attachBuffer to output queue because it could block for a slow consumer. - Instead of setting the consumer buffer count of input buffer queue to maximum of all shared outputs, set it to sum of them. By doing this, In the case of a slow consumer, other consumers sharing the same stream won't be impacted. - Handle the case where onBufferReleased not being fired for buffer replaced by attachBuffer/queueBuffer. - Add function to check the return value of onFrameAvailable so that when output is abandoned, the error code is propagated back to queueBuffer. Test: Camera CTS, and CTS with StreamSplitter enabled for all implementation defined use cases. Bug: 33777818 Change-Id: I863f501d5283bbe70c71e66b4d37d690484b90fa
