Interface ITimedDataSource
An interface for a collection of timecoded data samples. Represents a data source that can be synchronized.
Namespace: Unity.LiveCapture
Syntax
public interface ITimedDataSource : IRegistrableProperties
BufferSize
Gets or sets the current buffer size.
Declaration
int BufferSize { get; set; }Property Value
| Type | Description |
|---|---|
| Int32 |
IsSynchronized
Signal to the data source whether it is being synchronized via PresentAt(Timecode, FrameRate).
Declaration
bool IsSynchronized { get; set; }Property Value
| Type | Description |
|---|---|
| Boolean |
Remarks
When true, the data source should disable its own update mechanism.
MaxBufferSize
Get the maximum size of the sample buffer, if limited.
Declaration
int? MaxBufferSize { get; }Property Value
| Type | Description |
|---|---|
| Nullable<Int32> |
MinBufferSize
Get the minimum size of the sample buffer, if limited.
Declaration
int? MinBufferSize { get; }Property Value
| Type | Description |
|---|---|
| Nullable<Int32> |
PresentationOffset
Apply this constant frame offset when invoking PresentAt(Timecode, FrameRate).
Declaration
FrameTime PresentationOffset { get; set; }Property Value
| Type | Description |
|---|---|
| FrameTime |
Remarks
Set this to non-zero if the captured data's timecodes are "off" from the true values.
For example, if you determined that the samples and timecodes as mismatched such that
each sample lags its timecode by 2 frames, you would set this property to
new FrameTime(2).
Synchronizer
Gets or sets the ISynchronizer controlling this source.
Declaration
ISynchronizer Synchronizer { get; set; }Property Value
| Type | Description |
|---|---|
| ISynchronizer |
Remarks
In most cases you can simply implement this as an auto-property. The default Unity.LiveCapture.Synchronizer will automatically assign this property when you call Unity.LiveCapture.Synchronizer.AddDataSource(Unity.LiveCapture.ITimedDataSource).
Methods
PresentAt(Timecode, FrameRate)
Set the currently active timecode for presentation.
Declaration
TimedSampleStatus PresentAt(Timecode timecode, FrameRate frameRate)Parameters
| Type | Name | Description |
|---|---|---|
| Timecode | timecode | The timecode that we wish to present |
| FrameRate | frameRate | The underlying framerate of the timecode value |
Returns
| Type | Description |
|---|---|
| TimedSampleStatus | A status representing the ability of the source to present at the requested timecode. |
