* Refactor FrameReader * decodeThread * delete frame * remove joined * continue * less diff * robust cv wait * cache fist 15 frames * notify_all * rename variables * need call avformat_find_stream_info before dump_format * get width&height from codec * use std::string * delete in removeSegment * use std::mutex in lockmgr_cb * fix wrong min/max * no get in process * cleanup * always notify decodeThread to do prefetch
