[FR] Search

[JuniorJPDJ]

It would be cool to have some sort of youtube search (videos/playlists) API in pytube.

Thank you for contributing to PyTube. Please remember to reference Contributing.md

i will port the code from https://github.com/HelloChatterbox/youtube_searcher over to this repo

I'm working on this feature now. Expect search functionality to be added soon.

[tfdahlin]

I think I have the functionality written, feel free to test out the branch I created. It currently only supports video search results, but at a future point in time it could also probably support playlist results fairly easily. I don't plan to merge this for at least a little while so that I can make sure it works how I want it too, to add documentation for the new feature, and to make sure there's nothing else I want to bundle with the update. However, you're welcome to try out the development branch for it in my fork

Please tell me how to stop the download? Is there a special method?

[tfdahlin]

What do you mean by stopping the download?

What do you mean by stopping the download?

Now YouTube limits the download speed if you download, for example, a playlist. If the speed drops a lot, then I want to programmatically stop rutube.YouTube(url).streams.first().download(). Is there a method for this?

[tfdahlin]

One way you could do this is by adjusting the default download chunk size to be smaller, and using an on_progress_callback. For example:

import pytube

pytube.request.default_range_size = 524288  # 0.5MB

def progress_func(data_chunk, bytes_remaining):
    # Check when last called and raise an exception here
    ...

p = Playlist(url)
for url in p.video_urls:
    video = YouTube(url, on_progress_callback=progress_func)
    video.streams.first().download()

for url in p.video_urls:
    video = YouTube(url, on_progress_callback=progress_func)
    video.streams.first().download()

Will this help solve the problem with the YouTube speed limit?

[tfdahlin]

No; i'm working on trying to fix the problem with the speed limit. If you want to test it, you can try using this experimental branch that I just got working this morning, but haven't had the chance to test extensively.

This method helped solve the YouTube speed limit. Thanks!
