* 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> * 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> * * <p>See {@link CaptureRequest#SENSOR_FRAME_DURATION android.sensor.frameDuration} * for more information about calculating the max frame rate (absent stalls).</p> * * @param format an image format from {@link ImageFormat} or {@link PixelFormat} * @param size an output-compatible size * @return a stall duration {@code >=} 0 in nanoseconds * * @throws IllegalArgumentException if {@code format} or {@code size} was not supported * @throws NullPointerException if {@code size} was {@code null} * * @see CaptureRequest#SENSOR_FRAME_DURATION * @see ImageFormat * @see PixelFormat */ public long getOutputStallDuration(int format, Size size) { checkArgumentFormatSupported(format, /*output*/true); return getInternalFormatDuration(imageFormatToInternal(format), imageFormatToDataspace(format), size, DURATION_STALL); } /** * Get the stall duration for the class/size combination (in nanoseconds). * * <p>This assumes a the {@code klass} is set up to use {@link ImageFormat#PRIVATE}. * For user-defined formats, use {@link #getOutputMinFrameDuration(int, Size)}.</p> * * <p>{@code klass} should be one of the ones with a non-empty array returned by * {@link #getOutputSizes(Class)}.</p> * * <p>{@code size} should be one of the ones returned by * {@link #getOutputSizes(Class)}.</p> * * <p>See {@link #getOutputStallDuration(int, Size)} for a definition of a * <em>stall duration</em>.</p> * * @param klass * a class which is supported by {@link #isOutputSupportedFor(Class)} and has a * non-empty array returned by {@link #getOutputSizes(Class)} * @param size an output-compatible size * @return a minimum frame duration {@code >=} 0 in nanoseconds * * @throws IllegalArgumentException if {@code klass} or {@code size} was not supported * @throws NullPointerException if {@code size} or {@code klass} was {@code null} * * @see CaptureRequest#SENSOR_FRAME_DURATION * @see ImageFormat * @see PixelFormat */ public <T> long getOutputStallDuration(final Class<T> klass, final Size size) { if (!isOutputSupportedFor(klass)) { throw new IllegalArgumentException("klass was not supported"); } return getInternalFormatDuration(HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED, HAL_DATASPACE_UNKNOWN, size, DURATION_STALL); } /** * Check if this {@link StreamConfigurationMap} is equal to another * {@link StreamConfigurationMap}. * * <p>Two vectors are only equal if and only if each of the respective elements is equal.</p> * * @return {@code true} if the objects were equal, {@code false} otherwise */ @Override public boolean equals(final Object obj) { if (obj == null) { return false; } if (this == obj) { return true; } if (obj instanceof StreamConfigurationMap) { final StreamConfigurationMap other = (StreamConfigurationMap) obj; // XX: do we care about order?
