创建mpp解码器实例失败

我也遇到了一样的问题,在跑入门教程的时候,官方的例子.
[toybrick@localhost build]$ ./rtsp_ssd
mpi: mpp version: Without VCS info
hal_h264d_api: Assertion vcodec_type & ((0x00000200) | (0x00000001) | (0x00000002)) failed at hal_h264d_init:104
hal_h264d_api: hal_h264d_init hard mode error, value=0
hal_h264d_api: Assertion 0 failed at hal_h264d_init:154
mpp_device: mpp_device_init failed to find device for coding 7 type 0
mpp_rt: NOT found ion allocator
mpp_rt: found drm allocator
Segmentation fault
请问知道是什么原因了吗?
