No. We should merge all the libraries into a single libffmpeg.so. Having
separate libraries brings us no end of hassle and drawbacks, starting
with all the avpriv symbols and backward compat

FFmpeg has instances of DECLARE_ALIGNED(32, ...) in a lot of structs,
which then end up heap-allocated.
By declaring any variable in a struct, or tree of structs, to be 32 byte
aligned, it allows the compiler to safely assume the entire struct
itself is also 32 byte aligned.
