av_printf_format is a preprocessor macro that expands to a built-in 
compiler attribute which enables compile-time printf-style format string 
checking. There is no support for such a feature in any D compiler.

You want

void av_log_ask_for_sample(void* avc, const(char)* msg, ...);


In case you want to preserve the attribute:

struct av_printf_format{ int fmtpos, attrpos; }

@av_printf_format(2, 3) void av_log_ask_for_sample(void* avc, 
const(char)* msg, ...);
