| libv4lconvert is not safe for using one convert instance as returned by |
| v4lconvert_create from multiple threads, if you want to use one v4lconvert |
| instance from multiple threads you must provide your own locking and make |
| sure no simultaneous calls are made. |
| |
| libv4l1 and libv4l2 are safe for multithread use *under* *the* *following* |
| *conditions* : |
| |
| * when using v4lx_fd_open, do not make any v4lx_ calls to the passed fd until |
| v4lx_fd_open has completed |
| |
| * all v4lx_ calls must be completed before calling v4lx_close |
