Yawcam refuses to start

Postby canon350d » Sun Jan 20, 2008 5:09 pm

I hate asking the question as the software is free in all but here goes:

I have a webcam uploading to a website using ftp, it worked perfectly! then one day I needed to upload a new pic i double clicked on the yawcam eye and nothing happens, i clicked on it again... nothing. I then uninstall yawcam and re install it, still no response. I also went through the start menu to launch it and also got no response.

Any advice?

Thanks in advance,

Is java correctly installed?

Press the windows key + R at the same time on your keyboard.
Type cmd in the run dialog and hit enter.
Type java -version in the command window and hit enter.

What does the output say?

I'm having a similar issue. Tried with the latest stable and latest Beta I could find (2007-06-11).

My issue is that Yawcam starts fine the first time, runs as expected. Very nice, in fact.

The second time, though, the .exe starts, then after a few seconds in the process list, disappears. I do not have admin rights on this computer (XP), and installed it as administrator into a directory in which I do have access. However, I've tried running it under my account and using 'run as' without success.

I tried deleting the XML config file between starts and it makes no difference either.

I installed Java SE 6.04 just for Yawcam... Version reports:

Code: Select all

java version "1.6.0_04"
Java(TM) SE Runtime Environment (build 1.6.0_04-b12)

If I reinstall over the top (either version), it works fine the first time (using the "Launch Yawcam" option at the end of the install) but fails every time thereafter, even if I don't change the settings.

Using the debug batch file found elsewhere on the forum, Yawcam detects the video devices, then the audio devices. Either during the audio device detection or just after is when an access violation occurs.

Code: Select all

# An unexpected error has been detected by Java Runtime Environment:
#  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x03433dfe, pid=6072, tid=7100

# Problematic frame:

I'm having the same problem as bugmenot-user. Starts fine after the install, but anytime after that, it disappears after the splash screen.

I can't find the debug batch file he mentioned.

Had the same problem with dsj.dll, on Vista X64

Downloaded the latest DSJ package here

Replaced dsj.dll in the YawCam folder
Replaced dsj.jar in the YawCam\lib folder

So far that seems to have solved the problem.
