 What I do:
 I am trying to list AVOptions of libavcodec in a GUI interface.
 I need to have a unique key for each AVOption. I thought it was possible
 with the name of the option...

 My problem:
 There are two options with the same name "ac". This option could be the
 number of audio channels, or the arithmetic coder.

 Content of libavcodec/options_tables.h:
 {"ac", "set number of audio channels", OFFSET(channels), AV_OPT_TYPE_INT,
 {.i64 = DEFAULT }, INT_MIN, INT_MAX, A|D|E},
 {"ac", "arithmetic coder", 0, AV_OPT_TYPE_CONST, {.i64 = FF_CODER_TYPE_AC
 }, INT_MIN, INT_MAX, V|E, "coder"},
