Camera is not working #216

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago

When I use 2.1.5 it works when I use the current trunk (downloaded at 
09-05-2011 18:37) and start the video source it only displays one message 
"video was stopped". The video is not displayed.

Just tested 4 different USB cameras - all work fine.

>> and start the video source 
Which video source? USB camera? File? IP camera? Should we gues?

I found there is and exception thrown. Here's the info

"System.InvalidCastException: Unable to cast COM object of type 
'System.__ComObject' to interface type 
'AForge.Video.DirectShow.Internals.IAMVideoControl'. This operation failed 
because the QueryInterface call on the COM component for the interface with IID 
'{6A2E0670-28E4-11D0-A18C-00A0C9118956}' failed due to the following error: 
Taki interfejs nie jest obsługiwany. (Exception from HRESULT: 0x80004002 
(E_NOINTERFACE)).\r\n   at 
AForge.Video.DirectShow.VideoCaptureDevice.WorkerThread(Boolean runGraph) 
\\Video.DirectShow\\VideoCaptureDevice.cs:line 667"

What can be causing this issue?

Added try/catch block around retrieving IAMVideoControl interface, since it 
seems like some USB camera drivers don't support this interface.

Committed in revision 1464. Will be released in version 2.2.0.
