I am using windows 10.

ghost commented 4 years ago

help me !!!

flyzsd commented 4 years ago

as the stack trace clearly points out, it fails to load the 32 bit dll on 64 bit JVM. two choice for you:

Compile the dll into 64 bit (maybe more challenging for you)
Use 32 bit JVM

ghost commented 4 years ago

Can you explain in detail?

flyzsd commented 4 years ago

this project is using this library lti-civil to communicate to USB camera.. At lower level, Java code is loading DLL via JNI to invoke OS specific APIs.

flyzsd commented 4 years ago

this lit-civil library is no longer properly maintained.. you better seek alternative solutions to use camera in JVM

flyzsd commented 4 years ago

I am afraid this project will not fit your purpose...

ghost commented 4 years ago

Can you guide me to achieve this https://github.com/flyzsd/mjpeg/issues/1#issuecomment-635179625 ?

Because , I am new to java web app.

flyzsd commented 4 years ago

it is easier that you download 32 bit JRE to run this program https://www.oracle.com/java/technologies/javase-jre8-downloads.html
