I'm trying to encode capture video using MS Video 9 Encoder.<p>

I've created a sample application in .Net2/C# using LEADTools 15 which captures live video and allows choosing from available video encoders.<p>

The list is composed using <b>AxLTMMLib.AxltmmCaptureCtrl.VideoCompressors</b> property<p>

WMVideo 8 DMO and WMVideo 9 DMO encoders are presented in the list.
However, when I'm trying to switch to them, I get a black screen.<p>

Then, I used <b>EditGraph()</b> function and GraphStudio utility to take a look at DirectShow graph, constructed by LEADTools' CaptureCtrl.
The graph was empty (only video source was presented on it).<p>

I also tried setting TargetFormat to ltmmCapture_TargetFormat.ltmmCapture_TargetFormat_Asf.<br>
But, that didn't change anything.<p>

Does that mean that LEADTools doesn't support Windows Media Encoders at all or I'm doing something frong?<p><br>

I searched the forums and only found this discussion
<a HREF="/SupportPortal/cs/forums/14097/ShowPost.aspx">http://support.leadtools.com/SupportPortal/cs/forums/14097/ShowPost.aspx</a><p>

but, this is not quite what I'm looking for.<p><br>

Any help will be appreciated.<p>

If you want to save your videos to wmv, set the TargetFormat to ltmmCapture_TargetFormat_Asf, ltmmCapture_TargetFormat_Asf_Compressor_Mux or ltmmCapture_TargetFormat_Asf_Mux without setting the video compressor.
This will automatically cause appropriate encoders to be used.

If you want to control the encoder begin used, you should use Windows Media profiles as explained by the forum post http://support.leadtools...orums/5867/ShowPost.aspx
