But the problem is we need to convert the files online based on the target format(it is like transcoding the files in to different file formats using single source file). for this we need to use a console application. As in the example all the params are taken by the dialogboxes of the control. is there any way to convert by setting the same settings by passing parameters. Thanks & Regards Ravi Kumar P    Report

For more information please read the following topics: 1) In the Multimedia API help file: - Programmatically Inserting a Processor Filter. - Access a Filter Interface.   2) In the Multimedia Filters help file: - LEAD H263 Encoder User Interface (2.0).   You will need to change a couple of things since you will be setting encoder properties, in addition to the resize Transform Filter properties, but the concept is the same.

I think it is storing the values some where. is it in the registry or in any file. please help me to add a resize filter and assign the properties to generate the 3gp files with different dimensions Regards Ravi Kumar P    Report

About storing the values, our DirectShow filters do that, but you can always override the stored values by changing them programmatically without displaying the property pages. Please check the topics I mentioned earlier, but in the COM help file. Adam Boulad LEADTOOLS Technical Support    Report
