# MediaFormatManager Class
 
This is a class factory that creates a reader for the specified video file using Media Processor add-on.
 
**Namespace:** [Aurigma.GraphicsMill.Codecs](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill_Codecs.htm.md)
 **Assembly:** Aurigma.GraphicsMill.Codecs.MediaProcessor (in Aurigma.GraphicsMill.Codecs.MediaProcessor.dll)
 
## Syntax
  
```
Public NotInheritable Class MediaFormatManager
```
 
```csharp
public sealed class MediaFormatManager
```
 
## Remarks
  
Use this class to create a reader of the appropriate type automatically based on the type of the specified video file.
 
This class is an analog of the [FormatManager](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Codecs_FormatManager.htm.md) class, but works with video files. The [FormatManager](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Codecs_FormatManager.htm.md) will not return Media Processor readers automatically.
 
For the list of file formats supported by different Media Processor readers, see the [System Requirements](https://www.graphicsmill.com/docs/gm5/MediaProcessorSystemRequirements.htm.md) topic.
 
## Examples
 This example shows how to create a reader. ```
'Create a reader using the class factory
Private Sub CreateReader(ByVal fileName As String)
    Try
        reader = MediaFormatManager.CreateFormatReader(fileName)
    Catch ex As System.Exception
        MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, _
            MessageBoxIcon.Error)
    End Try
End Sub
``````csharp
//Create a reader using the class factory
private void CreateReader(String fileName)
{
    try
    {
        reader = MediaFormatManager.CreateFormatReader(fileName);
    }
    catch(System.Exception ex)
    {
        MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK,
            MessageBoxIcon.Error);
    }

}
```
