the functions you listed are probably a pretty accurate list of what needs a
mutex other functions like avcodec_encode/decode_* dont need a mutex, you
can encode or decode several things at once, of course you cannot call 2
avcodec_* functions with the same AVCodecContext at the same time, if that
could hapen then your application is missdesigned and you will likely have
various problems even with a mutex
and yes each encoder and decoder needs its own context ...

also all the simple utility functions like ff_gcd() are fully threadsafe
