Detailed Description

A Device representing a video stream from the hard disk.

Member Function Documentation

◆ Dispose()

override void Dispose ( bool disposing )

protectedvirtual

Additionally disposes the associated VideoImage if present.

Parameters

disposing

Reimplemented from Device.

Property Documentation

◆ PlaybackMode

PlaybackMode PlaybackMode

getset

Gets or sets how images are delivered by the stream.

Exceptions

InvalidOperationException Changing the acquisition interface while grabbing is not allowed.

◆ ReplayRate

double ReplayRate

getset

Gets or sets the current replay rate.

The replay rate must be in between ReplayRateMin and ReplayRateMax and is a factor that is applied to the individual frame time.

◆ VideoImage

VideoImage VideoImage

get

Gets the VideoImage of this video device.

The returned video image always points to the current location of the video stream.
