Syntax

public struct ArRecordingConfig : IEquatable<ArRecordingConfig>, IDisposable

Remarks

A ArRecordingConfig represents a native object that must be disposed (by calling Dispose()) to prevent memory leaks. Consider using a using statement for convenience:

void RecordExample(ARCoreSessionSubsystem subsystem, string mp4Path)
{
    var session = subsystem.session;
    using (var config = new ArRecordingConfig(session))
    {
        config.SetMp4DatasetFilePath(session, mp4Path);
        config.SetRecordingRotation(session, 90);
        config.SetAutoStopOnPause(session, false);
        var status = subsystem.StartRecording(config);
        Debug.Log($"StartRecording to {config.GetMp4DatasetFilePath(session)} => {status}");
    }
}

This is a C# wrapper for ARCore's native ArRecordingConfig

Constructors

ArRecordingConfig(ArSession)

Creates a dataset recording config object. This object must be disposed with Dispose().

Declaration

public ArRecordingConfig(ArSession session)

Parameters

Type	Name	Description

AsIntPtr()

Gets the underlying native pointer for this ArRecordingConfig.

Declaration

public IntPtr AsIntPtr()

Returns

Type	Description
IntPtr	Returns the underlying native pointer for this ArRecordingConfig.

bool	Returns true if the underlying native pointers are the same. Returns false otherwise.

Remarks

Two ArRecordingConfigs are considered equal if their underlying pointers are equal.

FromIntPtr(IntPtr)

Create a ArRecordingConfig from an existing native pointer. The native pointer must point to an existing ArRecordingConfig.

Returns

Type	Description
ArRecordingConfig	Returns an ArRecordingConfig whose underlying native pointer is value.

Gets the setting that indicates whether this recording should stop automatically when the ARCore session is paused.

Declaration

public bool GetAutoStopOnPause(ArSession session)

Parameters

Type	Name	Description
ArSession	session	The ARCore session.

Returns

Type	Description
bool	Returns true if this recording should stop when the ARCore session is paused. Returns false otherwise.

GetHashCode()

Generates a hash code suitable for use with a HashSet or Dictionary

Declaration

public override int GetHashCode()

Returns

Type	Description
int	Returns a hash code for this ArRecordingConfig.

Overrides

ValueType.GetHashCode()

GetMp4DatasetFilePath(ArSession)

Gets the file path to save an MP4 dataset file for this recording.

Declaration

public string GetMp4DatasetFilePath(ArSession session)

Parameters

Type	Name	Description
ArSession	session	The ARCore session.

Returns

Type	Description
string	Returns the path to the MP4 dataset file to which the recording should be saved.

GetRecordingRotation(ArSession)

Gets the clockwise rotation in degrees that should be applied to the recorded image.

Declaration

public int GetRecordingRotation(ArSession session)

Parameters

Type	Name	Description
ArSession	session	The ARCore session.

Returns

Type	Description
int	Returns the rotation in degrees that will be applied to the recorded image. Possible values are 0, 90, 180, 270, or -1 if unspecified.

SetAutoStopOnPause(ArSession, bool)

Sets whether this recording should stop automatically when the ARCore session is paused.

Declaration

public void SetAutoStopOnPause(ArSession session, bool value)

Parameters

Type	Name	Description
ArSession	session	The ARCore session.
bool	value	If true, this recording will stop automatically when the ARCore session is paused. If false, the recording will continue.

SetMp4DatasetFilePath(ArSession, string)

Sets the file path to save an MP4 dataset file for the recording.

Declaration

public void SetMp4DatasetFilePath(ArSession session, string path)

Parameters

Type	Name	Description
ArSession	session	The ARCore session.
string	path	The file path to which an MP4 dataset should be written.

Exceptions

Type	Condition
ArgumentNullException	Thrown if path is null.

SetRecordingRotation(ArSession, int)

Specifies the clockwise rotation in degrees that should be applied to the recorded image.

Declaration

public void SetRecordingRotation(ArSession session, int value)

Parameters

Type	Name	Description
ArSession	session	The ARCore session.
int	value	The clockwise rotation in degrees (0, 90, 180, or 270).

Operators

operator ==(ArRecordingConfig?, ArRecordingConfig?)

Tests for equality.

Declaration

public static bool operator ==(ArRecordingConfig? lhs, ArRecordingConfig? rhs)

Parameters

Type	Name	Description
ArRecordingConfig?	lhs	The nullable ArRecordingConfig to compare with rhs.
ArRecordingConfig?	rhs	The nullable ArRecordingConfig to compare with lhs.

Returns

Type	Description
bool	Returns true if any of these conditions are met: - lhs and rhs are both not null and their underlying pointers are equal. - lhs is null and rhs's underlying pointer is null. - rhs is null and lhs's underlying pointer is null. - Both lhs and rhs are null. Returns false otherwise.

Remarks

This equality operator lets you to compare an ArRecordingConfig with null to determine whether its underlying pointer is null. This allows for a more natural comparison with the native ARCore object:

bool TestForNull(ArRecordingConfig obj)
{
    if (obj == null)
    {
        // obj.AsIntPtr() is IntPtr.Zero
    }
}

operator ==(ArRecordingConfig, ArRecordingConfig)

Tests for equality. Same as Equals(ArRecordingConfig).

Declaration

public static bool operator ==(ArRecordingConfig lhs, ArRecordingConfig rhs)

Parameters

Type	Name	Description
ArRecordingConfig	lhs	The ArRecordingConfig to compare with rhs.
ArRecordingConfig	rhs	The ArRecordingConfig to compare with lhs.

Returns

Type	Description
bool	Returns true if lhs is equal to rhs using Equals(ArRecordingConfig). Returns false otherwise.

explicit operator IntPtr(ArRecordingConfig)

Casts an ArRecordingConfig to its underlying native pointer.

Declaration

public static explicit operator IntPtr(ArRecordingConfig config)

Parameters

Type	Name	Description
ArRecordingConfig	config	The ArRecordingConfig to cast.

Returns

Type	Description
IntPtr	Returns the underlying native pointer for config

operator !=(ArRecordingConfig?, ArRecordingConfig?)

Tests for inequality.

Declaration

public static bool operator !=(ArRecordingConfig? lhs, ArRecordingConfig? rhs)

Parameters

Type	Name	Description
ArRecordingConfig?	lhs	The native object to compare with rhs.
ArRecordingConfig?	rhs	The native object to compare with lhs.

Returns

Type	Description
bool	Returns false if any of these conditions are met: - lhs and rhs are both not null and their underlying pointers are equal. - lhs is null and rhs's underlying pointer is null. - rhs is null and lhs's underlying pointer is null. - Both lhs and rhs are null. Returns true otherwise.

Remarks

This inequality operator lets you to compare an ArRecordingConfig with null to determine whether its underlying pointer is null. This allows for a more natural comparison with the native ARCore object:

bool TestForNull(ArRecordingConfig obj)
{
    if (obj != null)
    {
        // obj.AsIntPtr() is not IntPtr.Zero
    }
}

operator !=(ArRecordingConfig, ArRecordingConfig)

Tests for inequality. Same as the negation of Equals(ArRecordingConfig).

Declaration

public static bool operator !=(ArRecordingConfig lhs, ArRecordingConfig rhs)

Parameters

Type	Name	Description
ArRecordingConfig	lhs	The ArRecordingConfig to compare with rhs.
ArRecordingConfig	rhs	The ArRecordingConfig to compare with lhs.
