The VideoLAN Forums

Hi all,

I am new to the board. I am having some trouble with the capturing functionality of VLC. I have successfully captured from a framegrabber (Terratec G3) via dshow, using the commandline interface (Windows 7). The only problem is, VLC will only work with a resolution of 352x288 px. When I use the ":dshow-size"-parameter, it writes only audio, no video. Also using the GUI, I cannot get VLC to accept higher resolutions; when I check "device properties", in the dialogue that appears I can, in fact, chose different resolutions, but when I chose a higher one, no video will appear, only audio is played. (When i chose smaller resolutions - just for testing - VLC crashes on me, sometimes even giving me a blue screen). And one other things: this is apparently NOT a problem that is device-specific: with all other capturing tools I tested, capturing higher resolutions was possible, so it must be a problem to do with VLC; however, i really need VLC to work, because it is the only one with such a good command line interface. Any help is really more than welcome!

Hi,

thanks for the quick reply.

Oh, and VLC version is 1.0.5, tested latest release too: same problem, but worse performance in general, so went back to 1.0.5.

If this helps: this is the command line I am using:

cd "C:\Program Files (x86)\VideoLAN\VLC"
start vlc.exe -vvv dshow:// :dshow-vdev="TerraTec G3 Capture" :dshow-adev="Line (9- TerraTec G3)" :dshow-size="640 x 480" --sout=#transcode{fps=25,vcodec=I420,acodec=s16l,scale=1}:standard{access=file,mux=avi,dst="C:\Vout1\00087.avi"} --run-time=6600

It should be:dshow-size="640x480"

i tried that too, same result...

Does it matter if you change dshow FPS to different one?

No, unfortunately that doesn't help either...

Does it work better if you change video encoder to something else?

I am sorry, that too makes no difference. As I said, I cannot even get VLC to display the stream using the GUI. It will play only the audio from the capture device, but no video. I really don't know what else to try...
