Convert mp4 to wav/mp3 via ffmpeg

ffmpeg -i input.mp4 input.mp4.wav

You can reduce the file size

ffmpeg -i input.mp4 -ar 22050 -ab 128k output.wav
ffmpeg -i input.mp4 input.mp4.mp3

Bash Script

Put the convert code into the bash script.

function .toWAV() {
  .log "ffmpeg -i $1 ${1%.mp4}.wav"
  ffmpeg -i $1 ${1%.mp4}.wav
}

function .toSrt() {
  .log "./main -m ./models/ggml-base.en.bin -f $1 -osrt"
  cd ~/pythonProject/whisper.cpp && ./main -m ./models/ggml-base.en.bin -f $1 -osrt
}
