我正在做一个 WebRTC 项目。我选择 OpenWebRTC 在我的项目中实现。

我已经让它适用于 web 和 iOS。我在 asp.net MVC 中开发了一个信令服务器,并使用 coTurn 服务器作为转向服务器。

除一个问题外,一切正常。

iOS应用程序随机崩溃,但有异常

EXC_BAD_ACCESS 异常:(gstglcontext(14):EXC_BAD_ACCESS (code=1,address=0x30))

异常是从 SDK 中的某处引发的。我已经尝试了几天来找到解决方案,但到目前为止还没有成功。

有没有其他人遇到过类似的问题?

以下是来自崩溃设备日志的堆栈跟踪

我进一步追踪了这个问题。

在函数“gst_glimage_sink_on_draw”的 gstglimagesink.c 中的以下行中引发异常

gl->Clear (GL_COLOR_BUFFER_BIT);

将 gstreamer 库更新到版本 1.10.4。较新版本的 gstreamer 已修复此错误。要更新修改脚本 'update-gst.sh' 如下 master_commit=git ls-remote git://anongit.freedesktop.org/git/gstreamer/$i | grep "1.10.4$" | awk '{print $1}'

然后运行脚本,然后首先为 os x 和 iOS 进行干净的构建。

gl->Clear (GL_COLOR_BUFFER_BIT);

在那一行gl是一个类型的虚拟转换表GstGLFuncs。是包含用户数据GstGLFuncs的类型的成员。struct GstGLContext

很明显,您没有尝试访问的用户数据。你有一个悬空指针。这可能是因为

  1. 指针(在您的情况下GstGLContext)曾经指向正常的内存,但它的块已被释放。
  2. 指针已损坏。

您的应用程序崩溃的代码行不是问题的根本原因。#1 中的问题是导致过早释放的任何代码行,而 #2 中的问题是任何代码行破坏了指针。
