| /** |
| * <p>Duration from start of frame exposure to |

| * <p>The maximum frame rate that can be supported by a camera subsystem is |
| * a function of many factors:</p> |
| * <ul> |
| * <li>Requested resolutions of output image streams</li> |
| * <li>Availability of binning / skipping modes on the imager</li> |
| * <li>The bandwidth of the imager interface</li> |
| * <li>The bandwidth of the various ISP processing blocks</li> |
| * </ul> |
| * <p>Since these factors can vary greatly between different ISPs and |
| * sensors, the camera abstraction tries to represent the bandwidth |
| * restrictions with as simple a model as possible.</p> |
| * <p>The model presented has the following characteristics:</p> |
| * <ul> |
| * <li>The image sensor is always configured to output the smallest |
| * resolution possible given the application's requested output stream |
| * sizes. The smallest resolution is defined as being at least as large |
| * as the largest requested output stream size; the camera pipeline must |
| * never digitally upsample sensor data when the crop region covers the |
| * whole sensor. In general, this means that if only small output stream |
| * resolutions are configured, the sensor can provide a higher frame |
| * rate.</li> |
| * <li>Since any request may use any or all the currently configured |
| * output streams, the sensor and ISP must be configured to support |
| * scaling a single capture to all the streams at the same time. This |
| * means the camera pipeline must be ready to produce the largest |
| * requested output size without any delay. Therefore, the overall |
| * frame rate of a given configured stream set is governed only by the |
| * largest requested stream resolution.</li> |
| * <li>Using more than one output stream in a request does not affect the |
| * frame duration.</li> |
| * <li>JPEG streams act like processed YUV streams in requests for which |
| * they are not included; in requests in which they are directly |
| * referenced, they act as JPEG streams. This is because supporting a |
| * JPEG stream requires the underlying YUV data to always be ready for |
| * use by a JPEG encoder, but the encoder will only be used (and impact |
| * frame duration) on requests that actually reference a JPEG stream.</li> |
| * <li>The JPEG processor can run concurrently to the rest of the camera |
| * pipeline, but cannot process more than 1 capture at a time.</li> |
| * </ul> |
| * <p>The necessary information for the application, given the model above, |
| * is provided via the android.scaler.available*MinDurations fields. |
| * These are used to determine the maximum frame rate / minimum frame |
| * duration that is possible for a given stream configuration.</p> |
| * <p>Specifically, the application can use the following rules to |
| * determine the minimum frame duration it can request from the HAL |
| * device:</p> |
| * <ol> |
| * <li>Given the application's currently configured set of output |
| * streams, <code>S</code>, divide them into three sets: streams in a JPEG format |
| * <code>SJ</code>, streams in a raw sensor format <code>SR</code>, and the rest ('processed') |
| * <code>SP</code>.</li> |
| * <li>For each subset of streams, find the largest resolution (by pixel |
| * count) in the subset. This gives (at most) three resolutions <code>RJ</code>, |
| * <code>RR</code>, and <code>RP</code>.</li> |
| * <li>If <code>RJ</code> is greater than <code>RP</code>, set <code>RP</code> equal to <code>RJ</code>. If there is |
| * no exact match for <code>RP == RJ</code> (in particular there isn't an available |
| * processed resolution at the same size as <code>RJ</code>), then set <code>RP</code> equal |
| * to the smallest processed resolution that is larger than <code>RJ</code>. If |
| * there are no processed resolutions larger than <code>RJ</code>, then set <code>RJ</code> to |
| * the processed resolution closest to <code>RJ</code>.</li> |
| * <li>If <code>RP</code> is greater than <code>RR</code>, set <code>RR</code> equal to <code>RP</code>. If there is |
| * no exact match for <code>RR == RP</code> (in particular there isn't an available |
| * raw resolution at the same size as <code>RP</code>), then set <code>RR</code> equal to |
| * or to the smallest raw resolution that is larger than <code>RP</code>. If |
| * there are no raw resolutions larger than <code>RP</code>, then set <code>RR</code> to |
| * the raw resolution closest to <code>RP</code>.</li> |
| * <li>Look up the matching minimum frame durations in the property lists |
| * {@link CameraCharacteristics#SCALER_AVAILABLE_JPEG_MIN_DURATIONS android.scaler.availableJpegMinDurations}, |
| * android.scaler.availableRawMinDurations, and |
| * {@link CameraCharacteristics#SCALER_AVAILABLE_PROCESSED_MIN_DURATIONS android.scaler.availableProcessedMinDurations}. This gives three |
| * minimum frame durations <code>FJ</code>, <code>FR</code>, and <code>FP</code>.</li> |
| * <li>If a stream of requests do not use a JPEG stream, then the minimum |
| * supported frame duration for each request is <code>max(FR, FP)</code>.</li> |
| * <li>If a stream of requests all use the JPEG stream, then the minimum |
| * supported frame duration for each request is <code>max(FR, FP, FJ)</code>.</li> |
| * <li>If a mix of JPEG-using and non-JPEG-using requests is submitted by |
| * the application, then the HAL will have to delay JPEG-using requests |
| * whenever the JPEG encoder is still busy processing an older capture. |
| * This will happen whenever a JPEG-using request starts capture less |
| * than <code>FJ</code> <em>ns</em> after a previous JPEG-using request. The minimum |
| * supported frame duration will vary between the values calculated in |
| * #6 and #7.</li> |

| * it may start streaming control changes that span over several frame |
| * boundaries.</p> |
| * <p>In the latter case, whenever a request's settings change relative to |

| * device, for more details see pipeline considerations below).</li> |
| * <li>Submitting a series of multiple requests that differ from the |
| * previous request (e.g. r1, r2, r3 s.t. r1 != r2 != r3) |
| * moves the new synchronization frame to the last non-repeating |
| * request (using the smallest frame number from the contiguous list of |
| * repeating requests).</li> |
| * <li>Submitting the same request repeatedly will not change this value |
| * to CONVERGING, if it was already a non-negative value.</li> |
| * <li>When this value changes to non-negative, that means that all of the |
