rk3566 mpp解码jpg图片错误

[xlwlp]

decode_put_packet返回值是1，这个错误我在头文件里没找到 typedef enum { MPP_SUCCESS = RK_SUCCESS, MPP_OK = RK_OK,

MPP_NOK                     = -1,
MPP_ERR_UNKNOW              = -2,
MPP_ERR_NULL_PTR            = -3,
MPP_ERR_MALLOC              = -4,
MPP_ERR_OPEN_FILE           = -5,
MPP_ERR_VALUE               = -6,
MPP_ERR_READ_BIT            = -7,
MPP_ERR_TIMEOUT             = -8,
MPP_ERR_PERM                = -9,

MPP_ERR_BASE                = -1000,

/* The error in stream processing */
MPP_ERR_LIST_STREAM         = MPP_ERR_BASE - 1,
MPP_ERR_INIT                = MPP_ERR_BASE - 2,
MPP_ERR_VPU_CODEC_INIT      = MPP_ERR_BASE - 3,
MPP_ERR_STREAM              = MPP_ERR_BASE - 4,
MPP_ERR_FATAL_THREAD        = MPP_ERR_BASE - 5,
MPP_ERR_NOMEM               = MPP_ERR_BASE - 6,
MPP_ERR_PROTOL              = MPP_ERR_BASE - 7,
MPP_FAIL_SPLIT_FRAME        = MPP_ERR_BASE - 8,
MPP_ERR_VPUHW               = MPP_ERR_BASE - 9,
MPP_EOS_STREAM_REACHED      = MPP_ERR_BASE - 11,
MPP_ERR_BUFFER_FULL         = MPP_ERR_BASE - 12,
MPP_ERR_DISPLAY_FULL        = MPP_ERR_BASE - 13,

} MPP_RET; 请问这个是什么错误，通过errno查看到的信息是No such file or directory
