- *
- *   When Zero Shutter Lag (ZSL) is supported by the camera device, the INPUT stream
- *   can be used for application/framework implemented ZSL use case. This kind of stream
- *   will be used by the framework as follows:
- *
- *   1. Framework configures an opaque raw format output stream that is used to
- *      produce the ZSL output buffers. The stream pixel format will be
- *      HAL_PIXEL_FORMAT_RAW_OPAQUE.

- *   2. Framework configures an opaque raw format input stream that is used to
- *      send the reprocess ZSL buffers to the HAL. The stream pixel format will
- *      also be HAL_PIXEL_FORMAT_RAW_OPAQUE.
- *
- *   3. Framework configures a YUV/JPEG output stream that is used to receive the
- *      reprocessed data. The stream pixel format will be YCbCr_420/HAL_PIXEL_FORMAT_BLOB.
- *
- *   4. Framework picks a ZSL buffer from the output stream when a ZSL capture is
- *      issued by the application, and sends the data back as an input buffer in a
- *      reprocessing request, then sends to the HAL for reprocessing.
- *
- *   5. The HAL sends back the output JPEG result to framework.
- *
- *   The HAL can select the actual raw buffer format and configure the ISP pipeline
- *   appropriately based on the HAL_PIXEL_FORMAT_RAW_OPAQUE format. See this format
- *   definition for more details.
