The capture card works fine when I select "Default" in the menu or leave the command line MRL "parameter" :dshow-adev blank. I get the following console output as expected when it binds (is that the correct term?) the capture card:

Code: Select all

dshow debug: found device: AVerMedia AVerTV Audio Capture
dshow debug: found device: IDT Audio1
dshow debug: asking for default device: AVerMedia AVerTV Audio Capture
dshow debug: asked for AVerMedia AVerTV Audio Capture , binding to AVerMedia AVerTV Audio Capture

But when I manually select the capture card in the menu, the logs give an error in the binding step instead:

Code: Select all

dshow debug: found device: AVerMedia AVerTV Audio Capture
dshow debug: found device: IDT Audio1
dshow debug: asking for device: AVerMedia AVerTV Audio Capture
dshow debug: can't use device device: AVerMedia AVerTV Audio Capture, unsupported device type

Should I be setting anything in the advanced menu (or adding extra MRL "parameters") if I manually select the capture device? I'm guessing that setting "Default" does some magic autoconfiguration I'm not aware of.

I would guess that this is a whitespace issue,

Code: Select all

msg_Dbg( p_this, "asked for %s, binding to %s", p_devicename->c_str() , devname.c_str() ) ;

and since you get

Code: Select all

asked for AVerMedia AVerTV Audio Capture ,

(notice the space between Capture and ,)
I would guess that your device name has unneeded whitespace at the end.

Yep, that was it!

I'll go report the bug: the interface must be trimming whitespace from the device name when it generates the MRL.

EDIT: Oh, looks like it was already reported here https://trac.videolan.org/vlc/ticket/3220 but it was marked as a duplicate for some weird parsing issue at https://trac.videolan.org/vlc/ticket/1906. Should I just let open bug reports lie?

I think courmisch has marked it as duplicate correctly.
