did you try new ffmpeg packages in https://sourceforge.net/projects/avbuild/files/android/ ? master and 4.3 has no textrel, and should work for you.

It doesn't work with FFmpeg 4.3

With FFmpeg 4.3 I have got this error:

E AndroidRuntime: java.lang.UnsatisfiedLinkError: dlopen failed: invalid ELF file "/data/app/com.myapp-rb7Psob8RiU4X8aXiqQuKw==/lib/x86/libswscale.so" load segment[4]: p_offset (0xc1000) + p_filesz (0x0) ( = 0xc1000) past end of file (0xc04a4)
