AviCompressor.CompressorDataSize Property

[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.

[C#]
private void cmdSaveCodecData_Click( object sender, System.EventArgs e )
{
    if( edtConfigFile.Text != "" )
    {
        try
        {
            System.IO.FileStream Filestream = new System.IO.FileStream( edtConfigFile.Text, System.IO.FileMode.Create, System.IO.FileAccess.Write );
            // Create the writer for data.
            System.IO.BinaryWriter BinWriter = new System.IO.BinaryWriter( Filestream );
            // Write data to Test.data.
            AviCompressor aviComp = null;
            aviComp = ((AviCompressor)(CodecBox.SelectedItem));
            BinWriter.Write( aviComp.ToString() );
            BinWriter.Write( aviComp.CompressorDataSize );
            BinWriter.Write( aviComp.CompressorData );
            BinWriter.Close();
            Filestream.Close();
        }
        catch( Exception Ex )
        {
            MessageBox.Show( Ex.Message, "Write error", MessageBoxButtons.OK, MessageBoxIcon.Error );
        }
    }
}

Load the previously saved data and assign it to a codec.

[C#]
private void cmdLoadCodecData_Click( object sender, System.EventArgs e )
{
    if( edtConfigFile.Text != "" )
    {
        try
        {
            // Create the reader for data.
            System.IO.FileStream Filestrem = new System.IO.FileStream( edtConfigFile.Text, System.IO.FileMode.Open, System.IO.FileAccess.Read );
            System.IO.BinaryReader BinReader = new System.IO.BinaryReader( Filestrem );
            string CodecName = "";
            AviCompressor Codec = null;
            bool CodecFound = false;
            // Retrieve the name of the codec from the codec configuration file
            CodecName = BinReader.ReadString();
            // Search this codec in the codec combo box
            CodecFound = false;
            foreach( AviCompressor item in CodecBox.Items )
            {
                if( item.ToString() == CodecName )
                {
                    CodecBox.SelectedItem = item;
                    Codec = item;
                    CodecFound = true;
                }
            }
            if( CodecFound == true )
            {
                int codecDataLen = BinReader.ReadInt32();
                // Assign the configuration data to the codec.
                Codec.CompressorData = BinReader.ReadBytes( codecDataLen );
            }
            else
            {
                // If the codec was not found, display an error message.
                MessageBox.Show( "The codec " + CodecName + " was not found!", "Load codec configuration", MessageBoxButtons.OK, MessageBoxIcon.Information );
            }
            BinReader.Close();
            Filestrem.Close();
        }
        catch( Exception Ex )
        {
            MessageBox.Show( Ex.Message, "Read error", MessageBoxButtons.OK, MessageBoxIcon.Error );
        }
    }
