Execute multiple instances of zxing binary in parallel? #45

Closed logidelic closed 7 years ago

logidelic commented 7 years ago

I read in a previous issue that the library is not thread safe. In my case I'm not making use of the library directly (yet), but instead just executing the zxing binary and eating the output.

If multiple threads may execute zxing processes in parallel, is it still safe? Or does this need to be protected against (presumably because the process make use of some shared resource)?

Thanks.

The library is not thread-safe. However, you can run the library in multiple processes no problems.
