how to build ffmpeg shared libraries without version suffix
24 octobre 2017, par andruidois there a way i can configure to build ffmpeg shared libraries for android without version number suffixes ? im able to build with different options but always get files like "libavcodec.so.57". i would need the libraries without suffixes like "libavcodec.so". i thought the option "—disable-symver" would do the trick but unfortunately it didn’t. the problem is that i have a library (.so file) that depends on ffmpeg shared libraries without suffixes and therefore can’t load those im getting built.
i have followed mostly the instructions here. -
