创建mpp解码器实例失败

1月份出厂的固件，默认是没有打开VPU的。
请更新到V1.3，或更新内核到最新代码，并手动编译内核

1月份出厂的固件，默认是没有打开VPU的。
请更新到V1.3，或更新内核到最新代码，并手动编译内核 ...

更新固件到V1.3后，
安装librockchip_mpp-tests-1.3.7-10.rockchip.fc28.aarch64
运行mpi_test,
[toybrick@localhost bin]$ mpi_test
mpi_test: mpi_test start
mpi_test: mpi_test decoder test start
mpi: mpp_create enter ctx 0x7fd8875b70 mpi 0x7fd8875b78
mpi: mpp version: Without VCS info
mpi: mpp_create leave ret 0 ctx 0x280bb440 mpi 0x7f800af4a0
mpi: mpp_init enter ctx 0x280bb440 type 0 coding 0
mpp: unable to create unsupported type 0 coding 0
mpi: mpp_init leave ret -1
mpi_test: mpp_init failed
mpi: mpp_destroy enter ctx 0x280bb440
mpi: mpp_destroy leave ret 0
mpi_test: mpi_test failed
还是不正常
这两个设备文件权限如下：
[toybrick@localhost /]$ ls -l /dev/rkvdec
crw-rw-rw- 1 root root 244, 0 7月 22 15:53 /dev/rkvdec
[toybrick@localhost /]$ ls -l /dev/vpu_service
crw-rw-rw- 1 root root 245, 0 7月 22 15:53 /dev/vpu_service

你回下上面addy所要的信息

照addy所说，更新固件到1.3了，尝试运行mpi_test进行测试，测试失败，具体信息在下面的回复中

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?

请问楼主的问题解决了吗？我也遇到了相似的问题如下，
[toybrick@toybrick test]$ ./mpp_info_test
mpp_info_test: mpp revision is 0
mpp_info_test: mpp info all:
Without VCS info
mpp_info_test: mpp info revision: -1
mpp_info_test: mpp info date :
mpp_info_test: mpp info author  : Unknown

--------------

这是另一个例程执行情况：

[toybrick@toybrick test]$ ./mpi_test
mpi_test: mpi_test start
mpi_test: mpi_test decoder test start
mpi: mpp_create enter ctx 0x7fe9add220 mpi 0x7fe9add228
mpi: mpp version: Without VCS info
mpi: mpp_create leave ret 0 ctx 0x1e28b460 mpi 0x7f969934c8
mpi: mpp_init enter ctx 0x1e28b460 type 0 coding 0
mpp: unable to create unsupported type 0 coding 0
mpi: mpp_init leave ret -1
mpi_test: mpp_init failed
mpi: mpp_destroy enter ctx 0x1e28b460
mpi: mpp_destroy leave ret 0
mpi_test: mpi_test failed

-------------

固件是刷的资料库里最新的TB-RK3399ProD-v1.5.zip
设备文件权限也是一样：

[toybrick@toybrick test]$ ls -l /dev/rkvdec
crw-rw-rw- 1 root root 244, 0 Feb 20  2019 /dev/rkvdec
[toybrick@toybrick test]$ ls -l /dev/vpu_service
crw-rw-rw- 1 root root 245, 0 Feb 20  2019 /dev/vpu_service

后面认真看了一下，这些demo写得有问题，不用管
