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
