Solution using array:
Take extension list from current directory and subdirectories. Look your ls -1R output, if this need fixing (special lines like directory). This use assosiative array of ksh.
Code:
#!/bin/ksh
#listext
typeset -A exts
ls -1R | while read line
do
     case "$line" in
           "") continue ;; # empty line
           *:)  continue ;; # dir
     esac
     ext=${line##*.}
     [ "$ext" = "$line" ] && continue # no ext
     # or if you like to count also files without ext, then ex. mark those -
     # "$ext" = "$line" ] && ext="-"
     exts["$ext"]=1
done

for ext in ${!exts[*]}
do
     echo "$ext"
done

Code:
chmod a+rx listext
./listext > result.txt

gst-launch-ext

GStreamer(1)															      GStreamer(1)

NAME

       gst-launch-ext - Run a predefined GStreamer pipeline

SYNOPSIS

       gst-launch-ext filename [filename...]

DESCRIPTION

       gst-launch-ext  is  a  tool  that  is  used to run a basic predefined GStreamer pipeline.  This application is only used as a quick test to
       ensure proper working of codecs and GStreamer.  It doesn't handle more advanced features like synchronisation.

       All supported formats in GStreamer should be playable by simply typing:

	gst-launch-ext filename

       It will also print out the pipeline it uses, so you can customize it using cut and paste.

CONFIGURATION

       gst-launch-ext can be configured by creating a .gst file in your home directory.  This is a perl-style configuration file and can  override
       the defaults for audio and video output sinks.

       Here is an example .gst file that implements the same defaults as hard-coded in the script :

       $cfg{AUDIOSINK} = "osssink"; $cfg{VIDEOSINK} = "colorspace ! xvideosink";

       You  can  change  osssink  to  any  of  esdsink,  alsasink,  jacksink (if you have the plug-in), and you can change xvideosink to aasink or
       sdlvideosink.

       Other plug-ins might be used as well if GStreamer has them.
