Add a more accurate description of what the switches actually do (i.e.
allow using the given library, not enabling the corresponding
codecs etc.).
Replace the library descriptions, in many cases boilerplate text without
useful information, with a short summary of what the library does.

+ Using any of the following switches will allow Libav to link to the
+ corresponding external library. All the components depending on that library
+ will become enabled, if all their other dependencies are met and they are not
+ explicitly disabled. E.g. --enable-libwavpack will enable linking to
+ libwavpack and allow the libwavpack encoder to be built, unless it is
+ specifically disabled with --disable-encoder=libwavpack.
+
+ Note that only the system libraries are auto-detected. All the other external
+ libraries must be explicitly enabled.

opencore-amrwb is only for decoding, it doesn't include an encoder.
(That's what vo-amrwbenc is for.)
+ --enable-libopencv computer vision
+ --enable-libopenh264 H.264 video encoding/decoding
We only have the encoder half of OpenH264 hooked up
