它的工作完美的第一次，但是当我尝试没有任何异常的code崩溃然后再运行它的第二次，当我尝试运行它为它工作在崩溃后的第三次！  没有任何一个有任何想法的这种行为？

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?

我也开发有微调视频中的一个模块的应用程序。 我真的AP preciate它，如果任何人能帮助我。

I am also developing an application which has one module of trimming videos. I would really appreciate it, if any one could help me .
