| /** |
| * <p>This lists the maximum stall duration for each |
| * format/size combination.</p> |
| * <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> |
| * <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 |
| * active, with all processing (typically in android.*.mode) set to FAST |
| * 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 |
| * ignored).</p> |
| * <p>The following formats may always have a stall duration:</p> |
| * <ul> |
| * <li>JPEG</li> |
| * <li>RAW16</li> |
| * </ul> |
| * <p>The following formats will never have a stall duration:</p> |
| * <ul> |
| * <li>YUV_420_888</li> |
| * <li>IMPLEMENTATION_DEFINED</li> |
| * </ul> |
| * <p>All other formats may or may not have an allowed stall duration on |
| * a per-capability basis; refer to {@link CameraCharacteristics#REQUEST_AVAILABLE_CAPABILITIES android.request.availableCapabilities} |
| * for more details.</p> |
| * <p>See {@link CaptureRequest#SENSOR_FRAME_DURATION android.sensor.frameDuration} for more information about |
| * calculating the max frame rate (absent stalls).</p> |
