DM6467T编码程序初始化过程中出现有时死机的问题

liang wang4

我使用的是DM6467处理器做多媒体开发，编码参考ti官网的程序，编码程序共有capture video audio writer(存盘) ctrl 5个线程，板子编码程序之前一直运行正常的，突然从前段时间开始，编码程序运行有时启动过程中编码初始化时程序死掉，机器死机了。

具体是程序运行到video线程的这句话的时候：hVe1 = Venc1_create(hEngine, envp->videoEncoder, params, dynParams);

我是新手，不知道什么原因造成的，大家帮忙提供一下意见，谢谢。
