经过我长达两个小时的反复测试，目前V1.12和V1.13版本的缩略图功能仅对放入QUEST2主机中的影片有效，而对通过WIFI读取电脑硬盘的方式无效，即使清除缓存、改变全英文路径格式、给影片换各种名字，都无效，望修复！
After two hours of repeated testing, I have found that the thumbnail functionality of versions V1.12 and V1.13 is only effective for videos placed in the QUEST2 host. It does not work for videos accessed via WIFI from a computer hard drive. Even after clearing cache, changing to all-English path formats, and trying various file names, the issue remains unresolved. I hope for a fix!
