Error linking "libav" plugin on Android

[ivan-perez]

Hi there!
I have tried the examples on the Android tutorial - all of them worked fine.
Because of my application requirements, now I need to add the *libav*
plugin. As far as I've read, this plugin will allow me to convert a /H264/
video into /raw/ and then reproduce it in a Android media player component.
So this is the variable where I declare what plugins I need on my
/Android.mk/ file:
GSTREAMER_PLUGINS := $(GSTREAMER_PLUGINS_CORE) $(GSTREAMER_PLUGINS_CODECS)
$(GSTREAMER_PLUGINS_SYS) x264 *libav*
The target architecture is /armv7/. No matter if I compile only that plugin
or if it is among others, the linker always fail. This is the error I get:
C:/Users/User/AppData/Local/Android/sdk/ndk-bundle/build//../toolchains/arm-linux-androideabi-4.9/prebuilt/windows-x86_64/lib/gcc/arm-linux-androideabi/4.9.x/../../../../arm-linux-androideabi/bin\ld.gold.exe:
error: conditional branch to PLT in THUMB-2 not supported

while processing relocation R_ARM_THM_JUMP19clang.exe: error: linker command
failed with exit code 1 (use -v to see invocation)make: ***
[buildsharedlibrary_armeabi-v7a] Error 1
I'm using the latest NDK version available. I've also tried to disable the
*gold linker* and use the old NDK linker (*bfd*) and I get a very similar
error:
C:/Users/User/AndroidStudioProjects/gstreamer-android/armv7/lib/libswresample.a(audio_convert_neon.o):

error: linker command failed with exit code 1 (use -v to see
invocation)make: *** [buildsharedlibrary_armeabi-v7a] Error 1
Is there anything I can do in order to build my application with that
plugin?
Thank you very much.
Kind regards
