Comment (by cehoyos):

 Iiuc, you argue that the parameter short_name of av_guess_codec() should
 have precedence over the parameter fmt. Why do you think so? The function
 is there for over ten years, and its (arguably undocumented) behaviour was
 always that the fmt parameter has precendence.
 Or to say it differently: Why don't you pass "test.flac" to
 av_guess_format?
