Hi,
I use a Logitech QuickCam USB (Driver version 7 recently updated).
Everything works fine, exept save to AVI, even in the demo application. The error message is:
An unexpected DShowLibException occured: CFilterGraph::addFilter(CFilter& op2, WMVideo8 Encoder DMO ) : failed to add the filter to the graph
COM Error Message: Un error de certificación originó errores en la operación.
In file: C:\CSource\core\DShoeLib\FilterGraph.cpp at line : 196
This happens with the following codecs: WMVideo Encoder DMO and WMVideo8 Encoder DMO, other Microsoft codecs produce other errors. I want to use this codecs, because "I think" they produce the best quality with small file size and low CPU utilization (is this true? do recommend other codec instead?)
I tried this on two machines:
1.- W2K Server SP3 Spanish, P III 750 MHz dual processor, 512 MB RAM (This machine has Windows Media Encoder 7 installed and it works fine).
2.- WinXP Pro (no SP1) Spanish, P 4 1.8 GHz, 512 MB RAM (This machine does not have Windows Media Encoder installed. It's a clean install, it only has VStudio 6.0 SP5 Spanish, IC Imaging and, of course, all of the winXP patches)
The file wich raises the error (C:\CSource\core\DShoeLib\FilterGraph.cpp) does not exist in any of these machines. Because one is installed in drive E: and the other is in drive I:. "??????" (Verified with Windows Explorer, may be is a temp file).
I think the problem is the MS Codec, does this save to AVI files? I think it doesn't.
Best Regards
