too many libraries when loading *.so
July 24, 2013
在加载so库的时候，碰见这个问题，原因是因为加载的so库超过了android系统定义的上限。上限的值定义在bionic/linker/linker.c 的SO_MAX 这个常量上。
Binoic是android的内核，Bionic imposes a hard limit on the number of shared objects you can load at run time.There are a few ways to work around this issue:
If you're not using a huge pipeline that actually requires to load a number of plugins at runtime that makes you hit the limit, you can use GST_REGISTRY_REUSE_PLUGIN_SCANNER=no and it should work (This was implemented in GStreamer by commit dd9f244f033ba3978d6ee26d9205d29fdd862d7c, Oct 18/2011 so please check you have a recent enough version).
If your pipeline is complex enough so it makes you hit the limit no matter what. Then you have two alternatives:
The first one is to modify Android to change limit. You will be bumping SO_MAX to (for example) 128 in Android's bionic/linker/linker.c and rebuilding with make linker. Then you will need to install this customized version of Android on your device as it's explained in the Installing our bundle on the Nexus S section of this document.
SO_MAX 的值在不同的 android os 版本上是不同的，估计不同的手机厂商也是会有不同。比较早的版本，比如2.2的，可能会是64或者其他值，4.0，4.1，4.2的，可能是128或者192.修改这个值，可以通过自己修改源码，然后编译，刷机。
Another option is to explore building the plugins as static libraries. You can find a patch implementing this solution here: https://bugzilla.gnome.org/show_bug.cgi?id=667305
