Zuste tohle. Konvertuje to vse na mp3, vcetne .flv. Pokud potrebujete, dopiste si tam dalsi pripony souboru, musi je ale umet mplayer. Upravte si pripadne parametry kodovani do mp3. Pojmenujte to mp3ify. Nasel jsem to kdysi na webu a trochu upravil.
#!/bin/bash
# Script that will convert a lot of audio formats to MP3 via the commandline.
# Dependencies: MPlayer, mutagen and lame (It should accept every format that both mutagen and Mplayer accept).
# mp3ify <input_dir> [<output_dir>] transforms structure <input_dir>/X/Y/.../Z into structure <output_dir>/X/Y/.../Z according to the following rules:
# * flac, ogg, m4a, ape, aac, mpc files will be encoded to mp3 preserving tags.
# * Everything else will be copied without modification.
# Default output_dir is /tmp/mp3ify.
# lame settings fine-tunning is done editing the configuration variables here below.
