avutil/opt: Print out numeric values of option constants
It's often not obvious how option constants relate to numerical values. Defaults are sometimes printed as numbers and from/to are always printed as numbers. Printing the numeric values of options constants avoids this confusion. It also allows to see which constants are equivalent. Before this patch: -segment_list_type <int> E........ set the segment list type (from -1 to 4) (default -1) flat E........ flat format csv E........ csv format ext E........ extended format ffconcat E........ ffconcat format m3u8 E........ M3U8 format hls E........ Apple HTTP Live Streaming compatible Afterwards: -segment_list_type <int> E........ set the segment list type (from -1 to 4) (default -1) flat 0 E........ flat format csv 1 E........ csv format ext 3 E........ extended format ffconcat 4 E........ ffconcat format m3u8 2 E........ M3U8 format hls 2 E........ Apple HTTP Live Streaming compatible Signed-off-by: softworkz <softworkz@hotmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
