ffmpeg QAudio

FFmpeg is a popular open-source software library and command-line tool used for handling multimedia data. It supports various audio and video formats, encoding, decoding, transcoding, and streaming.

To extract audio from a video file using FFmpeg, you can use the following command:

ffmpeg -i input_video.mp4 -vn -acodec copy output_audio.mp3

Here's what each parameter does:
- `-i input_video.mp4`: Specifies the input video file.
- `-vn`: Disables video recording to only extract the audio.
- `-acodec copy`: Copies the audio stream without re-encoding.
- `output_audio.mp3`: Specifies the output audio file.

You can replace `input_video.mp4` with the path to your desired video file and `output_audio.mp3` with the desired name and format for your output audio file.
