Add a progress bar for the downloads

[Flowrey]

Problem to solve

Currently, there is no indication of the progression of a download

Proposal

Add a progress bar to see the progression

I would like to give it a try. Can you assign this issue to me?

[Flowrey]

Yeah, sure !

Code Details

I have used tqdm for adding progress bar

from tqdm import tqdm

Added a pbar global variable

global pbar
    pbar = tqdm(total=len(results))
    
    # Run download in thread pool to avoid blocking IO
    for result in results:
        if result:
            loop = asyncio.get_running_loop()
            loop.run_in_executor(
                None, download_video_audio, result["title"], result["id"], destination
            )

    pbar.close()

And, updating the pbar here:

def download_video_audio(title: str, video_id: str, destination: Optional[str] = None):
    """Download audio of a YouTube video."""
    print("[Downloading] {} : {}".format(title, video_id))
    if stream := pytube.YouTube(
        f"http://youtube.com/watch?v={video_id}"
    ).streams.get_audio_only():
        stream.download(output_path=destination)
    print("[Downloaded] {}".format(title))
    pbar.update(1)

I'm encountering an issue where multiple progress bars are being displayed.
Can you give me a heads up at where I might be approaching wrong?

Hey, i think the global here is what make you have multiple progress bars, we don't need one.
The idea is to update the progress bar when a Future completed.

You would need to use the asyncio module of tqdm, tqdm.asyncio.
And with that you should be able to do something like this:

from tqdm.asyncio import tqdm

   loop = asyncio.get_running_loop()

    # Run download in thread pool to avoid blocking IO
    tasks = []
    for result in results:
        if result:
            tasks.append(loop.run_in_executor(
                None, download_video_audio, result["title"], result["id"], destination
            ))

    for f in tqdm.as_completed(tasks):
        await f
