Now we have all parameters needed for the mp4 to mp3 conversion using FFmpeg. file_without_ext = os.path.splitext(file_name) os.path.splitext(file_name) will give us only the file name without the extension part. os.path.splitext() splits the extension and the rest of the file name. For that, I have taken the same name without the extension. We also need to set the output file with mp3 format. Up to now we have file name with mp4 extension. source.replace will do the same thing but, will assign the new name to file_name variable for us to use later. Os.rename replaces the white spaces with underscore in the downloaded mp4 file.
if ' ' in file_name: os.rename(source, source.replace(' ', '_')) file_name = source.replace(' ','_') So, I have replaced white spaces with underscore (_). Therefore, for the program to work correctly no white spaces are allowed in the file name. UPDATE: Path and file name needs to be taken as an input for the next step, which is to rename the file to exclude any white spaces. For that, we need the downloaded file name with extension. Next, it is required to start the conversion. Now the mp4 audio file should have been downloaded.
audio = yt.streams.get_audio_only() audio.download(output_path=path) UPDATE: Further, customized download path has been set using the output_path parameter. Once it is selected, the file can be downloaded using the download() method. Now, using the YouTube object we can get the highest bit-rate audio stream from the available codecs (defaults to mp4). video_url = input("Please enter the video URL: ") yt = YouTube(video_url) After that, YouTube object is created named yt. Then, we have to let the user to enter the YouTube URL and save it in video_url variable. For example, the following line will set the download path as D:\Music\Mix\. UPDATE: Path variable added to customize the download location. Delete the initially downloaded mp4 file after conversion.įirst of all we need to import the required libraries.UPDATE: Custom path can be set as the download location.Initially, downloads the highest bit-rate audio stream in mp4.Asks for user input to get the YouTube video URL.This code is written on Windows machine so some steps may differ for other operating systems.
Therefore, I thought to write a program that will help me to download and convert the audio files at once. Conversely, I prefer all my audio files to be in MP3 format. However, I saw that many online downloaders download the audio in MP4 format. I usually like to download music or songs from YouTube, just the audio.
