Detailed tutorial for installing ffmpeg under linux

If the following errors occur during installation:

yasm/nasm not found or too old. Use disable-yasm for a crippled build.

If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config. log" produced by configure as this will help
solve the problem.
