If the Android toolchain behaves like a normal Linux/Unix toolchain,
the (ffmpeg) linking process picks up the soname from the SONAME field
_within_ the dynamic library, not from the filename. (Perhaps from the
filename if said field does not exist.)
In the linking stage of the x264 _library_, you can give the linker a
flag to determine the soname:
So you may need to build your libx264.so.142, remove this file, run
"make -n" to identify the final linking command line, and modify this
command line with the corresponding ld flag.
$ objdump -p libx264.so | grep SONAME
You may be able to do binary patching to change this name. The tool
patchelf is capable ob binary ELF patching, but unfortunately doesn't
handle this field.
