Hi Fabrizio,
I've been working on a DirectShow video capture application using IEvolution and am currently creating the output AVI using:
Dim result As HiComponents.IEvolution.IEImage.CreateAVIFileResult
result = (IeViewer1.Image.CreateAVIFile("Output12.avi", 25, "dmb1"))
I am using the Morgan MJEG codec to write the AVI file (available from http://www.morgan-multimedia.com/morgan/php/products.php?sProductId=4&sProductSub=info ). I want to be able to access the Codec property pages for the codec that control the output parameters for the AVI (the Morgan MJPEG codec in this case), like I can for the DirectShow filters. Is this possible?
thanks

Hi Matt,
there is an unique way to show codec properties: set codec to an empty string. For example:
IeViewer1.Image.CreateAVIFile("Output12.avi", 25, "")
Selecting a codec, the "Configure" button should be enabled. Unfortunately it shows also the codec selection dialog. |

| CreateAVIFile doesn't use DirectShow, but the old api Video for Windows (VfW), so DirectShow property sheets aren't available. |

Thanks Fabrizio,
Can I capture video using Direct Show and then write frames to an AVI using direct show?
thanks

Yes, you can. Please look at directshow samples.
Anyway AVI writing is limited by VfW interface. |

Can you point me to which DirectShow sample? All I can see is the sample that calls the SaveToAVI method that I am currently using.
Much appreciated...matt |

VideoCapture\DirectShow4 - captures using directshow and save back using CreateAVIFile/SaveToAVI
VideoCapture\DirectShow1 - a bit more complex, but allows to specify a directshow filter on the output file. Just select webcam as input, and a file name as output (and a codec). |

Thanks Fabrizio.
I'll try to transfer that approach to my .Net application and see how I go. It makes sense so shouldn't be a problem. Appreciate the help. |
