MP3-files frame sizes

Could anybody help to understand, how mp3-encoder determine frame sizes (when packing music files), do their have some standart sizes and how i could determine this size?
Thanks a lot,
Oleg.

Most mp3 de- and encoding libraries have functions for it. You don't have to do the low-level work then (otherwise you wouldn't require the lib ;-) )

If you want to encode, liblame is a good choice.
For decoding I use mpeglib...

If you just want to play audio-data, you can use the SDL or something like this:

Code:

pid_x=fork();

if(!pid_x)

{

        stdin=freopen("/dev/null","r+",stdin);

        stdout=freopen("/dev/null","w+",stdout);

        stderr=freopen("/dev/null","w+",stderr);

        execlp("/usr/bin/mpg123","/usr/bin/mpg123","/path/to/your/mp3/file.mp3",NULL);

        printf("Error: Unable to execute the player!\n");

        exit(1);

}

Easy but nice solution used in many apps :-)
