Video Acquisition: Codec property page

The following diagram shows how you can use IC Imaging Control to modify the settings of a codec.

The sample application's window looks as follows:

First of all, the program fills the list lstCodecs with the names of all codecs that are installed on your system (see dialog on the right). This first step is based on the collection .AviCompressors. .AviCompressors.Count indicates the number of codecs found, while .AviCompressors(i) returns information about the i'th codec (as for instance its name):

Private Sub Form_Load()

    cmdCodecSettings.Enabled = False

    For i = 1 To ICImagingControl1.AviCompressors.Count
        lstCodecs.AddItem ICImagingControl1.AviCompressors(i).Name
    Next i

End Sub

When the user clicks one of the codecs, the event handler calls the according AviCompressor object and checks whether this codec provides a property page (AviCompressor.PropertyPageAvailable):

Private Sub lstCodecs_Click()

    Set codec = ICImagingControl1.AviCompressors(lstCodecs.ListIndex + 1)

    cmdCodecSettings.Enabled = codec.PropertyPageAvailable

End Sub

Clicking on "Codec Settings...", the user opens a dialog to modify the selected codec's settings:

Private Sub cmdCodecSettings_Click()

    codec.ShowPropertyPage

End Sub
