我已从 此链接从 github 下载了视频修剪代码.
I have downloaded video trimming code from github from this link.
它第一次运行完美，但是当我第二次尝试运行它时，代码毫无异常地崩溃，然后当我在崩溃后第三次尝试运行它时，它再次运行！有没有人对这种行为有任何想法?
It’s working perfectly for the first time, but when I try to run it for the second time the code crashes without any exception then again when I try to run it for the 3rd time after the crash it works! Does any one have any idea for this kind of behaviour?
