2021-01-12libcamera: pipelines: ipu3: Simplify error bail out path on start()Umang Jain
On the bail out path, always ensure that ImgU and CIO2 are stopped before freeing the buffers. V4L2VideoDevice class guarantees that calling stop() without having to call start() is harmless, hence use this guarantee to simplify error paths.

Ensuring that streamOff() can be called on non-streaming streams facilitates simpler error code paths, where a set of devices can all call streamOff regardless of their initialisation state.

2021-01-04android: camera_device: Only advertise RAW support if RAW16 is availableNiklas Söderlund
The Android camera2 API defines a RAW capture capability ([1]) for devices that support "outputting RAW buffers and metadata for interpreting them". This capability requires the camera device to support RAW_SENSOR ([2]) as an output format. Despite what its name may sound like, the RAW_SENSOR format is defined as a 16 bits RAW format, not an opaque implementation-dependent format (which is instead called RAW_PRIVATE). Devices may additionally support the RAW10 and RAW12 formats, but that isn't enough to claim RAW capture capability. To comply with the API requirements, only report the ANDROID_REQUEST_AVAILABLE_CAPABILITIES_RAW capability when 16-bit RAW is supported.

This wasn't really appropriate, it's better for the algorithms to do it as they know how many frames they might need. The CamHelper::HideFramesStartup method should now just be returning the number of frames to hide because they're bad/invalid in some way, not worrying about the AGC/AWB.

2020-12-07android: camera_device: Stop camera when re-configuring itJacopo Mondi
The Android camera device HAL3 specification does not require a camera to go through any explicit close() call between configurations. It is legitimate for a camera to be configured, a number of requests processed and then re-configured again without any explicit stop. The libcamera Android camera HAL starts the Camera at the first handled request, and only stops it at camera close time. This means that two camera configuration attempts in the same streaming session are only interleaved by capture requests handling. The libcamera::Camera state machine requires the Camera to be stopped before any configuration take place, and this currently doesn't happen. Fix this by stopping the camera and the associated worker thread if a configuration attempt is performed while the Camera is in running state.
