[FFmpeg-devel] [PATCH] cmdutils: change signature to list_fmts()

[Stefano Sabatini]

Make it accept a function returning a char *.

Fix warning:
ffmpeg.c: In function ?opt_audio_sample_fmt?:
ffmpeg.c:2877: warning: passing argument 1 of ?list_fmts? from incompatible pointer type
cmdutils.h:163: note: expected ?void (*)(char *, int,  int)? but argument is of type ?char * (*)(char *, int,  enum AVSampleFormat)?
