+ * <p>A stall duration is how much extra time would get added

+ * <p>For example, consider JPEG captures which have the following
+ * characteristics:</p>
+ * <ul>
+ * <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>In other words, using a repeating YUV request would result
+ * in a steady frame rate (let's say it's 30 FPS). If a single
+ * JPEG request is submitted periodically, the frame rate will stay
+ * at 30 FPS (as long as we wait for the previous JPEG to return each
+ * time). If we try to submit a repeating YUV + JPEG request, then
+ * the frame rate will drop from 30 FPS.</p>
+ * <p>In general, submitting a new request with a non-0 stall time
+ * stream will <em>not</em> cause a frame rate drop unless there are still
+ * outstanding buffers for that stream from previous requests.</p>
+ * <p>Submitting a repeating request with streams (call this <code>S</code>)
+ * is the same as setting the minimum frame duration from
+ * the normal minimum frame duration corresponding to <code>S</code>, added with
+ * the maximum stall duration for <code>S</code>.</p>
+ * <p>If interleaving requests with and without a stall duration,
+ * a request will stall by the maximum of the remaining times
+ * for each can-stall stream with outstanding buffers.</p>
+ * <p>This means that a stalling request will not have an exposure start
+ * until the stall has completed.</p>
+ * <p>This should correspond to the stall duration when only that stream is

+ * or OFF. Setting any of the processing modes to HIGH_QUALITY
+ * effectively results in an indeterminate stall duration for all
+ * streams in a request (the regular stall calculation rules are

+ * <p>The maximum frame rate that can be supported by a camera subsystem is

+ * <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>Certain format-streams may need to do additional background processing
+ * before data is consumed/produced by that stream. These processors
+ * 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.streamConfigurationMap field using
+ * {@link android.hardware.camera2.params.StreamConfigurationMap#getOutputMinFrameDuration}.
+ * 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 camera
+ * device:</p>
+ * <ol>
+ * <li>Let the set of currently configured input/output streams
+ * be called <code>S</code>.</li>
+ * <li>Find the minimum frame durations for each stream in <code>S</code>, by looking
+ * it up in android.scaler.streamConfigurationMap using {@link
+ * android.hardware.camera2.params.StreamConfigurationMap#getOutputMinFrameDuration}
+ * (with its respective size/format). Let this set of frame durations be
+ * called <code>F</code>.</li>
+ * <li>For any given request <code>R</code>, the minimum frame duration allowed
+ * for <code>R</code> is the maximum out of all values in <code>F</code>. Let the streams
+ * used in <code>R</code> be called <code>S_r</code>.</li>
+ * </ol>
+ * <p>If none of the streams in <code>S_r</code> have a stall time (listed in {@link
+ * android.hardware.camera2.params.StreamConfigurationMap#getOutputStallDuration}
+ * using its respective size/format), then the frame duration in <code>F</code>
+ * determines the steady state frame rate that the application will get
+ * if it uses <code>R</code> as a repeating request. Let this special kind of
+ * request be called <code>Rsimple</code>.</p>
+ * <p>A repeating request <code>Rsimple</code> can be <em>occasionally</em> interleaved
+ * by a single capture of a new request <code>Rstall</code> (which has at least
+ * one in-use stream with a non-0 stall time) and if <code>Rstall</code> has the
+ * same minimum frame duration this will not cause a frame rate loss
+ * if all buffers from the previous <code>Rstall</code> have already been

+ * <li><code>LIMITED</code> devices represent the
