示例代码是图片的，输出视频要怎样操作，还是vdec这个应用吗？之前没有搞过C，也没有接触过海思，还请请教，谢谢

该回答已被题主采纳为最佳答案

0xa00f800c报错是操作不允许，代码是sample_vdec的吗？还是单独写的测试程序？是不是VB没初始化？

是sample目录下的vdec，没有做任何改动的。

那就看看ko版本跟你的SDK版本是否一致，以前不一致报错是0xFFFFFFFFF

嗯，可能是这样问题，请问要如何把新的ko文件夹下内容导入到版子中，重新拷贝到mpp目录下，然后运行./load_ss928v100 -i，加载ko驱动，报错：ss928v100 insmod: can’t insert ‘sys_config.ko’: File exists
是不是这样并不能覆盖掉之前的ko下文件，要怎样操作呢？要重新烧入哪个模块？

先把之前的驱动加载屏蔽了，直接加载新的驱动

要怎样屏蔽，怎样加载呢？菜鸟一枚，请指教

找到./load_ss928v100在哪执行的，直接注释掉就可以了啊

我是有重新拷贝自己编译的ko到mpp目录下，然后运行./load_ss928v100 -a，加载ko驱动，报错：ss928v100 insmod: can’t insert ‘sys_config.ko’: File exists。你说的直接注释掉./load_ss928v100执行的地方不行吧。换另一个ko后也是要执行./load_ss928v100的
