Hello,
I would like to ask how to use "option" in vlm scripts. I need to start multiple webcams from 1 vlm file with unique marq and same time sub-filter for all.

Theoretically

Code: Select all

#1
new cam1 broadcast enabled

setup cam1 input dshow://:dshow-adev="none":dshow-vdev="MSI Star Cam 370i":dshow-caching=1000

setup cam1 option dshow-size=320x240
setup cam1 option sub-filter=time:marq
setup cam1 option time-position=9
setup cam1 option marq-marquee="cam1"

setup cam1 output #transcode{vcodec=DIV3,....

#2
new cam2 broadcast enabled

setup cam2 input dshow://...
...
setup cam2 option marq-marquee="cam2"
...

control cam1 play
control cam2 play

but it doesn´t work. Setup options dshow-size and option sub-filter=time:marq work, but options marq-marquee and time-position don´t. Values from general saved preferences are used instead.
It seems they are equal in command line, but not in vlm script.
Thanks for any hint.

options which work on command line with the

ption=value syntax will work in VLM. Those which only work with the --option=value syntax won't.

Albert, does your configuration work?
What I know is that VLC does not work on devices in same device name.

Hello,
It is a pity that I can´t run only one VLC and one VLM script. Are you plannig support for this for future versions?

I suppose that I have tu run several batch files with --options and so several VLCs

Videoman:

Hello Videoman,
I had not enough time to answer:
I have not tested this properly, but in WinME and 2 devices it seems to work.
Thanks to garthb76's patch (viewtopic.php?t=16319) I have a build, which shows me dshow DevicePaths: that is a very long sequence of characters and it is not comfortable to operate with them.
So I have another solution: I found the sequence with regedit.exe in Windows registers and I renamed FriendlyName to something unique (e.g. "StarCam 370i no1" etc). You can find your devices in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceClasses\ ...characters....\Device Parameters
or you can wait for a dshow VLC guru

I am not able to humanize garthb76's patch, so I use original VLC and altered windows.

Now I can say: this works

I have 3 MSI StarCam 370i No1 + No2 + No3 in the VLC dshow dialog.
Garthb76´patched vlc shows me DevicePath e.g.

Code: Select all

\\?\usb#vid_0c45&pid_60c0&mi_00#7&288bdd37&0&0000#{65e8773d-8f56-11d0-a3b9-00a0c9223196}\global

which I find in registers (the 2nd hit) and in sub-key change FriendlyName.
Works under WinXP SP2 and vlc-0.8.5-test1-20060322-0132

Hello,

VLM:
setup cam1 option dshow-size=320x240 works but
...:dshow-size=320x240:... from GUI command line doesn´t.
