You need to download those libraries too. I would go and search for those file names on google, download the RPM, and install them with the rpm -ivh command.
To make things easier for you, here are the files that you should be looking for.
libasound.so.1
libpng.so.2
These files are called dependencies, and the main program depends on these files. So unless and until you don't install these libraries, your kmplayer won't work.
