... when I use DirectShow source (Philips SAA7130-based tvtuner in my case), but vlc 0.7.2 works properly. Can I switch on any debugging to find out wtf?

OPen View -- Messages before trying to open the device.

Alternately, you can get VLC to open a separate debugger/log window. Open a command prompt in the directory with vlc. Run:

vlc --extraintf="logger" -vvv

What kind of crash? Blue screen? Video goes to a weird state?

my case is blue screen, and restart XP. my webcam is PC380 from Emprex .

I got the answer

Both version 0.8.1 and 0.8.0 work well after I set the video size as 640 x 480. I checked the website of the webcam company, and got to know the camera supports 640 x 480.

One tricky thing is that we have to leave a space character between the two numbers. VLC crashes my windows XP if there is no space, or the video size is not set at all.

Sounds like an oddity of your vendor's driver, as both my USB and framegrabber video works without a space. Ahh, well, as long as you know what works.

You can store the dshow size, using Settings -- Preferences. Click Advanced options, then go to Modules -- access2 -- dshow. You can also permanently set the particular camera input as your default , in Preferences. Do a Save after inputting size and/or selecting the device as your default, to make the settings persistent.

I once thought it's VLC's bug

By the way, do you know how to generate sdp file, so I can use VLC to broadcast live stream to Darwin Stream Server?

Thanks a lot.
