There was an old system (v4l) for accessing cameras, and it was changed to a new, incompatible system (v4l2). A lot of programs (most?) were updated to use the new system, but some programs were not updated.

The LD_PRELOAD trick allows old-style programs to operate with the new system, but it's meant to be only a temporary patch.

In short, if the LD_PRELOAD trick fixes an issue you're having, then the problem is in the program, not the driver.
