Thanks for the reply.
I've already though about that, but I hoped that there was a parameter from command line that could print a list the devices found.
BTW, I'm having some problem in the capturing the audio also specifying the device.
This is the batch file that launch VLC:
Code: Select all
%CD%\vlc\vlc.exe --dshow-adev="Microfono (Logitech Mic (QuickC" dshow:// --sout=#transcode{vcodec=mp2v,vb=1024,fps=30,width=320,acodec=mp2a,ab=128,scale=1,channels=2,deinterlace,audio-sync}:duplicate{dst=standard{access=file,mux=ps,dst="Output.mpg"},dst=display} --extraintf=logger -vv
In the Log, It seems that VLC opens correctly both the video, and select the correct audio device specified, but I get errors on the "araw" module for audio:

and I can't understand what I'm doing wrong, any help would be appreciated
As a side note, If I use the GUI to "Convert/Save" from the devices selected, I do get a correct file, video + audio, so I think it is not something like missing codex.
EDITED: Solved
In case that someone else is looking for the solution:
Note: I'm using VLC Portable version 2.0.0
from the GUI you can get what parameters are passed to the core uf VLC.
For example you can get those doing the following:
- start VLC
- "Media" -> "Stream" -> "Capture device"
- In the Device Selection, select the device you want to use
- at the bottom, hit "Show more options" and here you can see the first two parameters
- Hit "Stream" at the bottom
- select "Source", then hit the button "Next"
- select ehat type of steram, I streamed to file, so I chose "Add" and set the file name, hit "Next"
- now you can see the "Options setup" and here you see the transcode setting in accord to what you have chose, this is the second parameter.
I know that some other have posted a simila question, but since the poster wasn't able to get the result, I hope that this could be of some help.
In my case I got this:
Code: Select all
MRL = dshow://
Edit Options = :dshow-vdev=Logitech QuickCam E3500 :dshow-adev=Microfono (Logitech Mic (QuickC :live-caching=300
Streaming options = :sout=#transcode{vcodec=h264,vb=0,scale=0,acodec=mp4a,ab=128,channels=2,samplerate=44100}:duplicate{dst=file{dst=a.mp4},dst=display} :sout-keep
Source = dshow://
then you can pass these on the command line as parameters, paying some attention on using the string delimiter right for your operating system, so in wndows the command became:
Code: Select all
%CD%\vlc\vlc.exe dshow:// :dshow-vdev="Logitech QuickCam E3500" :dshow-adev="Microfono (Logitech Mic (QuickC" :live-caching=300 --sout="#transcode{vcodec=h264,vb=0,scale=0,acodec=mp4a,ab=128,channels=2,samplerate=44100}:duplicate{dst=display,dst=std{access=file,mux=mp4,dst='c.mp4'}}" --extraintf=logger -vv
(note the " " around the parameters).
