How to rebuilt libgstreamer_android.so with libc++ instead of gnustl?
Hi there!
I'm building a simple app basing on GStreamer's Android tutorial 2. I was trying to link tutorial-2.so with a static gst plugin which is built with libc++.
Building with ndk-build was fine. However, at runtime when the pipeline is set to be playing, I've encountered an error:
APP_ABI = armeabi-v7a APP_STL = c++_static

I'd like to ask if there's any way I could rebuilt gstream-android upon libc++? I've been struggling with Cerbero configurations but haven't found any way through.
Thanks a lot!
