  • Reference

Definition

Namespace:
Android.Hardware.Camera2.Params
Assembly:
Mono.Android.dll

Overloads

GetOutputMinFrameDuration(Class, Size)

Get the minimum CaptureRequest#SENSOR_FRAME_DURATION frame duration for the class/size combination (in nanoseconds).
GetOutputMinFrameDuration(Int32, Size)

Get the minimum CaptureRequest#SENSOR_FRAME_DURATION frame duration for the format/size combination (in nanoseconds).

GetOutputMinFrameDuration(Class, Size)

Get the minimum CaptureRequest#SENSOR_FRAME_DURATION frame duration for the class/size combination (in nanoseconds).

[Android.Runtime.Register("getOutputMinFrameDuration", "(Ljava/lang/Class;Landroid/util/Size;)J", "")]
[Java.Interop.JavaTypeParameters(new System.String[] { "T" })]
public long GetOutputMinFrameDuration (Java.Lang.Class? klass, Android.Util.Size? size);
[<Android.Runtime.Register("getOutputMinFrameDuration", "(Ljava/lang/Class;Landroid/util/Size;)J", "")>]
[<Java.Interop.JavaTypeParameters(new System.String[] { "T" })>]
member this.GetOutputMinFrameDuration : Java.Lang.Class * Android.Util.Size -> int64

Parameters

klass
Class

a class which is supported by #isOutputSupportedFor(Class) and has a non-empty array returned by #getOutputSizes(Class)

size
Size

an output-compatible size

Returns

Int64

a minimum frame duration > 0 in nanoseconds, or 0 if the minimum frame duration is not available.

Attributes
RegisterAttribute JavaTypeParametersAttribute

Remarks

Get the minimum CaptureRequest#SENSOR_FRAME_DURATION frame duration for the class/size combination (in nanoseconds).

This assumes that the klass is set up to use ImageFormat#PRIVATE. For user-defined formats, use #getOutputMinFrameDuration(int, Size).

klass should be one of the ones which is supported by #isOutputSupportedFor(Class).

size should be one of the ones returned by #getOutputSizes(int).

This corresponds to the minimum frame duration (maximum frame rate) possible when only that stream is configured in a session, with all processing (typically in android.*.mode) set to either OFF or FAST.

When multiple streams are used in a session, the minimum frame duration will be max(individual stream min durations). See #getOutputStallDuration for details of timing for formats that may cause frame rate slowdown when they are targeted by a capture request.

For devices that do not support manual sensor control (android.hardware.camera2.CameraMetadata#REQUEST_AVAILABLE_CAPABILITIES_MANUAL_SENSOR), this function may return 0.

The minimum frame duration of a stream (of a particular format, size) is the same regardless of whether the stream is input or output.
