Hi @elainejo21

Please provide more details:

• What Webcam Capture version is used,
• What OS.

[elainejo21]

os- win 7 then webcam-capture-0.3.10-RC4.jar

[elainejo21]

then i have slf4j-api-1.7.2.jar, bridj-0.7-20130703.103049-42.jar, slf4j-simple- api-1.7.2.jar

this works fine for a month but since this morning, it did not work and receive the error above

@elainejo21

Please upgrade to 0.3.10-RC6 since this bug has been already reported in #131 and fixed about 4 months ago in 0.3.10-RC5.

If for some reason you don't wont to upgrade (don't worry, RC6 is fully compatible with RC4 since there was only bug fixes implemented in the middle), you can go to your TEMP directory and remove all files starting with .webcam-lock-*. But please note that, if you not upgrade, this problem will most probably happen again!

[elainejo21]

but i will use the same code?

[sarxos]

Yes. Only JAR must be updated to newer one.

[elainejo21]

it works now! you are so great! thanks :)

[sarxos]

You're welcome :)

from where shall i download webcam-capture-0.3.10-RC6.jar

[sarxos]

The newest one is 0.3.10-RC7 and you can find it here (webcam-capture-0.3.10-RC7-dist.zip). However, if you still want to use RC6, the you can find it here, but please note that there were many fixes introduced in RC7.
