You should use the NULL_IF_CONFIG_SMALL() macro to define it.

const char* AVCodec::name |
Name of the codec implementation.
The name is globally unique among encoders and among decoders (but an encoder and a decoder can share the same name). This is the primary way to find a codec from the user perspective.

int(* AVCodec::update_thread_context)(AVCodecContext *dst, const AVCodecContext *src) |
Copy necessary context variables from a previous thread context to the current one.
If not defined, the next thread will start automatically; otherwise, the codec must call ff_thread_finish_setup().
dst and src will (rarely) point to the same context, in which case memcpy should be skipped.
