ffmedia报错Segmentation fault (core dumped)

sky-brid

运行官方的ffmedia的demo_opencv.py，当长时间运行时，会报错Segmentation fault (core dumped)，无其他任何报错信息就单独一条Segmentation fault (core dumped)，然后程序停止；ffmedia最近2星期前才升级到v2.0.1，请问后续还有升级计划吗，后续升级会尝试解决上述问题吗

ffmedia会持续更新支持；请具体描述一下复现方法，比如使用demo的命令是什么？

有基于demo进行过一点改动，在外面包了一层，可以开启多个demo获取不同的rtsp流，今天测试的时候出现新的报错信息：

啊这？能否给个复现环境或者复现方法，我这边能复现出来就容易解决

我这边上传了一个我改动过的demo，整体改动应该也不大，请大佬帮忙看看一下长时间运行会不会报上面的错，运行环境应该只需要OpenCV和ffmedia，给一个runserver.py里面的source_rtsp的可用rtsp地址，运行runserver应该就可以了。提取码：pjof

你那边大概运行多久会出问题？你们的rtsp是有多流吗（比如有音频流及字幕流）？
如果你们这样同步处理的话，可以不用导出rga模块buf，在回调中直接锁住等待和通知处理线程，等处理线程处理完成后，再通知回调函数退出回调，只要不退出回调，那么回调的那块buff就归你使用，当回调退出，模块会回收并使用该buf；
导出buf是从模块的内存池抽离，模块不再管理该buf，是为了支持异步处理buf，

时间说不准，有时候能运行好十几小时，有时候2.3小时就没了，我用的rtsp流是直接从摄像头获取的，带音频的；我研究一下安装你给的建议试试看

我这边海康摄像机一个流测试一晚上没出现问题，可能是多流导致的；前阵子修复了多流导致的问题，可能修复了他，下个星期更新一版。

我这边现在测试下来也没问题了，还有一个问题想请教一下，在前面还没改之前，我使用gunicron异步workers工作模式启动时，不知道是回调函数还是哪里总是出问题，无法获取到图像，换成同步worker就没有问题。
