The VideoLAN Forums

Hi folks,

I recently presented a problem I'm having with the Web Plugin in VB6 and VB 2005, as to why command line dshow:// capture works perfectly while Plugin addTarget dshow:// produces a blue screen, and was advised that "VLC log should tell you if something is wrong in your parameters".

When using the Web Plugin, where is the VLC log kept? Its not in the project directory, nor anywhere else that I can find.

Thank you!

produces a blue screen

You mean Blue screen of death (aka crash) or blue video output?

Blue video output.

Here's the original inquiry:

Thanks for any help!

Then I am guessing you have selected wrong pin.

Then I am guessing you have selected wrong pin.

I wasn't aware that the Web Plugin's addTarget method incorporates Graphedit pin assignments. From what I've read on forum, this should work:

VLCPlugin1.addTarget "dshow://", Array(":dshow-vdev=""Motorola AV/C Tuner Device""", ":dshow-adev="""""), VLCPlayListInsert, 0

Where would one select a pin?

This command-line using the client works perfectly:

vlc.exe" dshow:// --dshow-vdev="Motorola AV/C Tuner Device" --dshow-adev=""

This line of code using the Plugin produces a blue video screen:

VLCPlugin1.addTarget "dshow://", Array(":dshow-vdev=""Motorola AV/C Tuner Device""", ":dshow-adev="""""), VLCPlayListInsert, 0

Thank you!

Defaults for normal playback and ActiveX might be different ones, because current releases force certain options for ActiveX (e.g. --ignore-config). This should change on next release.

--dshow-video-output=<integer>
Video output pin
Select the video output type. See the "video input" option.

That should work.

Thanks. The "video input" option, as mentioned in the Command-Line help, suggests looking at the "video output" option to find the correct pin, be it "tuner", "svideo", etc, via "Device config".

"Device config" search produces that one particular Command-line reference.

In lieu of "video input" or "video output" actual integer data, I attempted a meticulous "--dshow-video-output=" value from -1 to over 100. both with client Command-line, and with ActiveX Plugin .addTarget array.

Regardless of the value given for client Command-line "--dshow-video-output=<integer>", the video output was perfect.

Regardless of the value fed into the array for .addTarget "options" array, the video output was blue.

It would be wondrous to see some VB6 - VB.NET 2005 - VB.NET 2008 code that reflects what the Command-line help's "video input" reference to "Device config", as regards "video output", is referring to.

Thank you for your patient reply!
