标题: [Core-3399Pro-JD4]MPP库的硬解码出现段错误（Segmentation Fault）
本帖最后由 mtsh 于 2020-5-20 08:53 编辑

固件版本号：AIO-RK3399PROC-UBUNTU18.04-GPT-20200321-1536.img
嵌入式操作系统：Ubuntu 18.04 64位
复现步骤如下：
1. 开三个子线程, 每个子线程拥有独立的MppContext实例；
2. 每个子线程里通过RTSP拉流，通过MPP API进行硬解码。
3. 利用gdb运行程序，程序正常运行一段时间后（3分钟到50分钟不固定），会出现段错误（Segmentation Fault）导致的崩溃，有2种表现形式，但在异常调用栈里统一都指向MppBufferService::get_group_by_id(unsigned int) () from /usr/lib/aarch64-linux-gnu/librockchip_mpp.so.1导致的段错误。

段错误（Segmentation Fault）2种表现形式的错误截图和对应的日志文件参见附件。

最后一张截图的call stack提供的信息量最大，欢迎MPP中间件的开发高手给些建议！

还有第3种表现形式，如下所示：
