[vlc] Directshow Input - Blue Screen of Death

[Brian Wang]

Hello all,

I am trying to get my webcam working in VLC through the DirectShow 
input and keep getting the blue screen hard crash.

Here is my findings, when doing [File] -> [Open Capture Device] -> 
[DirectShow]:
1. It works for the VLC 0.7.2 release version.
2. It works for VLC 0.8.0-test2.
3. It crashes for the VLC 0.8.0 release version and onwards, including the 
new vlc-trunk.

Is it a known problem? What should I do to debug the problem? What is the 
"professional"
way of debugging VLC under M$ Windows?
I tried adding msg_Dbg() calls across dshow.c, putting delays after each 
call and cross
compiled it under my Linux box. How can I find out where it crashed?
However, it does not help much as I think the messages are queued up
before BSOD. The log file shows VLC has gone through the DirectShow device 
enumeration though.

Here is some platform info:
1. Windows XP SP2 (Traditional Chinese version, if relevant)
2. Pentium III Mobile 1GHz with ATI Mobility Radeon AGP (Compaq Evo N410c).
The device tested is a USB webcam (UMAX AstraPix PC200).
3. VLC 0.8.0 and plus (VLC 0.7.2 works fine though)
4. Scenario: I presssed [Ctrl + C] to bring up the DirectShow dialog and 
pressed OK.
Then, the infamous blue screen appeared and a hard reset was required.
5. I can reproduce the problem every time. No exceptions.

What additional information may be provided to aid finding out the cause of 
the problem?

Thanks in advance. :-)
