AviCompressor.CompressorDataSize Property

[VB.NET]
Public CompressorDataSize As Integer

[C#]
public int CompressorDataSize;

Read only.

The CompressorDataSize is useful, if codec properties are to be saved to a file. Reading the size value first from file, enables an application to create an array of the matching size that will get the codec properties.

How to use the CompressorDataSize is shown in the sample Saving Codec Properties.

Save the data from a codec that was selected in a combo box.
