My aim is to create a wmv file out of this sequence to have a wmv video. Which framework should I use. I thougt to use DSPack / DirectShow to create a wmv file. How do I do that? I did not find any example with google. I also want to decode sound samples to the wmv video file! Thanks for any help!

Yes, it's too expensive. I really would like to use DSPack for creating wmf video files from a sequence of TBitmaps. Is there anyone who can give me a short code snippet or any URL where I can find some hints? I guess, I am not the first one who creates wmv videos from a TBitmap sequence using DSPack. Thanks for any idea!

Hi Steven. Thanks for your hint! How can I add sound samples to the video file? I have some sound raw data and want to encode it to the wmv file. Thanks for replying!

It is free for non commercial purposes, and it included a TVLASFLogger. Specify an WMF Profile file, and take a look at the RecordBitmapsDemo demo project to see how you can provide your own bitmaps.

Thank you Boian, I will have a look at your tool and test it. Is the source code of VideoLab available? I would be glad if I could use DSPack directly. I suppose you also use DSPack/DirectShow code to create wmv files?

DSPack the last time I worked with it, is a direct Delphi translation of some the DirectShow SDK VC++ foundation clases provided by Microsoft. It did not include all of them, and the original SDK lacks some necesary clases. There ware also a lot of bugs in the DSPack version at the time. I ended up using parts of the DSPack translation, and translating some of the original C++ clases my self. VideoLab has now its own translation, very similar to DSPack. You can't use the DSPack directly unless they have added a pusher filter. The last time I checked it was not there. I had to write my own push filter, as one was not even available in the M$ C++ foundation classes .

That will take a bitmap source file and render it to video. You will however need to do some coding to get it running the way you want, basically the pushsource demo filter only renders from a bmp file on disk, this is slow. If you want to do this in memory you need to add a com interface to the filter to pass the image data and also add some way to start and stop the playback until each frame's image buffer is full. I'd check the DSPack forum for more info on this. kimB Lars Blumberg wrote: Quote: Hello my dear newsgroup, I have a sequence of bitmaps (TBitmap instances).

With best regards, Boian Mitov Hello Boian, First I installed the trial version before byuing the full version. After the installation Delphi could not find the SignalLab*.bpl files, because they were installed to the wrong directory. I use a german version of Delphi. My bpl files are located in C:\Dokumente und Einstellungen\Lars Blumberg\Eigene Dateien\Borland Studio-Projekte\Bpl but your bpl files are installed to C:\Dokumente und Einstellungen\Lars Blumberg\Eigene Dateien\Borland Studio Projects\Bpl When starting Delphi it is looking for your bpl files in the first one, but they are located in the second one. When I copy the files to the first directory, everything works fine.

It works fine for creating avi video files. I am also able to use WMV3 video compression. But I cannot change the file extension of the TVLAVILogger from .avi to .wmv, because it creates avi files. Now my question is, Boian, how can I create a wmv video file? I suppose I cannot use the TVLAVILogger component for this. How do I do that? Thanks for help! Lars Back to top Boian Mitov Guest Posted: Thu May 18, 2006 2:15 pm    Post subject: Re: How to create a wmv video file using VideoLab? Hi Lars, To write into WMV you need to use the dedicated TVLASFLogger component. You will have to create compression profile first. Please check the online help for that.
