for vid in *.mp4; do ffmpeg -i "$vid" -vn -acodec libmp3lame "${vid%.mp4}.mp3"; done
que waxay u adeegaan dayactirka fiidiyowga ku kharribmay weel darteed, loogu beddelo .wav audio-ka .mp3, loogu beddelo qaab video ah mkv illaa avi, laga soo saaro raad-raac maqal ah oo fiidiyoow ah, loona gudbiyo dhammaan fiidiyowyada laga soo qaado (tusaale ahaan Youtube-ka, oo aan midba mid loo aadin) si loogu kala horreeyo .
