*
* <p>
* A stall duration is how much extra time would get added to the normal minimum frame duration
* for a repeating request that has streams with non-zero stall.
*
* <p>For example, consider JPEG captures which have the following characteristics:
*
* <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>The JPEG processor can run concurrently to the rest of the camera pipeline, but cannot
* process more than 1 capture at a time.
* </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}) is the same as setting
* the minimum frame duration from the normal minimum frame duration corresponding to {@code S},
* added with the maximum stall duration for {@code S}.</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 active, with all
* processing (typically in {@code android.*.mode}) set to {@code FAST} or {@code OFF}.
* Setting any of the processing modes to {@code HIGH_QUALITY} effectively results in an
* indeterminate stall duration for all streams in a request (the regular stall calculation
* rules are ignored).</p>
*
* <p>The following formats may always have a stall duration:
* <ul>
* <li>{@link ImageFormat#JPEG JPEG}
* <li>{@link ImageFormat#RAW_SENSOR RAW16}
* <li>{@link ImageFormat#RAW_PRIVATE RAW_PRIVATE}
* </ul>
* </p>
*
* <p>The following formats will never have a stall duration:
* <ul>
* <li>{@link ImageFormat#YUV_420_888 YUV_420_888}
* <li>{@link #isOutputSupportedFor(Class) Implementation-Defined}
* </ul></p>
*
* <p>
