我正在开发一个WebRTC项目.我选择OpenWebRTC在我的项目中实现.
我已经使它适用于Web和iOS.我在asp.net MVC中开发了一个信令服务器,并将coTurn服务器用作转弯服务器.
除了一个问题,一切都很好.
iOS应用程序随机崩溃,但异常
EXC_BAD_ACCESS exception:(gstglcontext(14):EXC_BAD_ACCESS (code=1,address=0x30))
从SDK中的某个位置抛出异常.我现在已经尝试了几天寻找解决方案,但到目前为止还没有成功.
还有其他人遇到过类似的问题吗？
以下是崩溃设备日志中的堆栈跟踪

我进一步追查了这个问题.
gstglimagesink.c中函数’gst_glimage_sink_on_draw’中的以下行抛出异常
gl->Clear (GL_COLOR_BUFFER_BIT);
解决方法
将gstreamer库更新到版本1.10.4.较新版本的gstreamer修复了这个bug.要更新,请修改脚本’update-gst.sh’,如下所示
master_commit = git ls-remote git：//anongit.freedesktop.org/git/gstreamer/$i | grep“1.10.4 $”| awk'{print $1}’
master_commit = git ls-remote git：//anongit.freedesktop.org/git/gstreamer/$i | grep“1.10.4 $”| awk'{print $1}’
然后运行脚本,之后先为os x做一个干净的构建,然后是iOS.
