| 20090601 - r19025 - lavc 52.30.0 - av_lockmgr_register() |
| av_lockmgr_register() can be used to register a callback function |
| that lavc (and in the future, libraries that depend on lavc) can use |
| to implement mutexes. The application should provide a callback function |
| the implements the AV_LOCK_* operations described in avcodec.h. |
| When the lock manager is registered FFmpeg is guaranteed to behave |
| correct also in a multi-threaded application. |
