使用mpi_enc_test遇到的问题
在使用mpi_enc_test时报错：
mpp[226406]: camera_source: camera_source_init get dma buf failed
mpp[226406]: mpi_enc_test: new framecap ok
mpp[226406]: mpi_enc_test: open /dev/video1 fail

camera_source_init get dma buf failed 确认下环境上 /dev/dma_heap/ 目录是否存在，是否用 root 权限运行测试用例
这个方法我已经尝试过了，运行 buffer test 还是报错
