VideoCapture

public @NonNull DynamicRange getDynamicRange()

Returns the dynamic range.

The dynamic range is set by setDynamicRange. If the dynamic range set is not a fully defined dynamic range, such as HDR_UNSPECIFIED_10_BIT, then it will be returned just as provided, and will not be returned as a fully defined dynamic range.

If the dynamic range was not provided to setDynamicRange, this will return the default of SDR

public int getMirrorMode()

Returns the mirror mode.

The mirror mode is set by setMirrorMode. If not set, it defaults to MIRROR_MODE_OFF.

public @NonNull T getOutput()

Gets the VideoOutput associated with this VideoCapture.

public @Nullable ResolutionInfo getResolutionInfo()

Returns information about the selected resolution.

Note that the getResolution might not be the same as the resolution of the recorded video because the video might have been rotated according to the camera sensor orientation and the target rotation, and/or have been cropped according to the androidx.camera.core.ViewPort settings. The recorded video resolution can be determined by applying the getRotationDegrees to the size of getCropRect.

The resolution information may change if:

• The use case is unbound and then rebound.
• setTargetRotation is called to change the target rotation.

If changes occur, the application should call getResolutionInfo() again to get the latest ResolutionInfo.

public @NonNull Range<Integer> getTargetFrameRate()

Returns the target frame rate range, in frames per second, for the associated VideoCapture use case.

The target frame rate can be set prior to constructing a VideoCapture using setTargetFrameRate If not set, the target frame rate defaults to the value of FRAME_RATE_RANGE_UNSPECIFIED

public int getTargetRotation()

Returns the desired rotation of the output video.

The rotation can be set prior to constructing a VideoCapture using setTargetRotation or dynamically by calling setTargetRotation. If not set, the target rotation defaults to the value of getRotation of the default display at the time the use case is bound.

public boolean isVideoStabilizationEnabled()

Returns whether video stabilization is enabled.

public void setTargetRotation(int rotation)

Sets the desired rotation of the output video.

Valid values include: ROTATION_0, ROTATION_90, ROTATION_180, ROTATION_270. Rotation values are relative to the "natural" rotation, ROTATION_0.

While rotation can also be set via setTargetRotation, using setTargetRotation(int) allows the target rotation to be set dynamically.

In general, it is best to use an android.view.OrientationEventListener to set the target rotation. This way, the rotation output will indicate which way is down for a given video. This is important since display orientation may be locked by device default, user setting, or app configuration, and some devices may not transition to a reverse-portrait display orientation. In these cases, set target rotation dynamically according to the android.view.OrientationEventListener, without re-creating the use case. snapToSurfaceRotation is a helper function to convert the orientation of the android.view.OrientationEventListener to a rotation value. See snapToSurfaceRotation for more information and sample code.

If not set, the target rotation will default to the value of getRotation of the default display at the time the use case is bound. To return to the default value, set the value to

context.getSystemService(WindowManager.class).getDefaultDisplay().getRotation();

For a Recorder output, calling this method has no effect on the ongoing recording, but will affect recordings started after calling this method. The final rotation degrees of the video, including the degrees set by this method and the orientation of the camera sensor, will be reflected by several possibilities, 1) the rotation degrees is written into the video metadata, 2) the video content is directly rotated, 3) both, i.e. rotation metadata and rotated video content which combines to the target rotation. CameraX will choose a strategy according to the use case.

public static @NonNull VideoCapture<T> <T extends VideoOutput> withOutput(@NonNull T videoOutput)

Create a VideoCapture associated with the given VideoOutput.
