Pytube: Pytube yt.streams giving empty streams list for some videos

[xenonstride]

I'm trying to download this(http://youtube.com/watch?v=hnGWlry_H_Q) or this (https://www.youtube.com/watch?v=j4JQFz_8XxU) from YouTube but when I use yt.streams it just gives an empty list without any streams.

Oh that's really weird. I'll try to look into this soon to see what's causing that.

@tfdahlin I tried earlier and there was an error on this line https://github.com/nficano/pytube/blob/fab1c34c3b6059697ed0288493d987ecbb273ae9/pytube/extract.py#L425, maybe because the regex doesn't match. Hopefully it helps.

hi, i'll try to look into this issue soon

[tfdahlin]

It's possible that this is related to the discussion on https://github.com/nficano/pytube/pull/808 where sometimes the metadata was in different spots for different videos.

Same Code @tfdahlin

On My Pc; Python 3.8.6

On Heroku; python-3.8.2

YouTube(url=url).streams.get_audio_only() returned None for some songs and not others.
i looked into it and noticed apply_descrambler from extract.py looks for "formats" and "adaptiveFormats" in the Youtube classes vid_info variable, and that for some songs the data downloaded via self.vid_info_raw = request.get(self.vid_info_url) in __main__.py dont contain "formats" or "adaptiveFormats"

I have the same with this video: https://www.youtube.com/watch?v=-EFjkY84Hlo

I ran a test on this video and It has the same issue. The data downloaded has no "formats" or "adaptiveFormats"

Ive been using these videos for testing
https://www.youtube.com/watch?v=L5KMO7lmLsA missing "formats" and "adaptiveFormats
https://www.youtube.com/watch?v=H7oOqMcDcbo has "formats" and "adaptiveFormats

I don't know if this is the root cause of the problem but I think its a good starting point

[michaelknudsen]

I fixed this issue by switching the user-agent in the requests.py file

I fixed this issue by switching the user-agent in the requests.py file

can you show the code ?

[michaelknudsen]

from
base_headers = {"User-Agent": "Mozilla/5.0", "accept-language": "en-US,en"}
to
agent = "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/77.0.3865.90 Safari/537.36" base_headers = {"User-Agent": agent, "accept-language": "en-US,en"}
in the _execute_request function in request.py

[tfdahlin]

I found the issue -- this was missing a key that should've been there from the get go. Going to fix and merge this quickly.

[tfdahlin]

Once the unit tests pass, I'll merge it to fix this problem

[tfdahlin]

To install the fix:
python -m pip install git+https://github.com/nficano/pytube

If there are additional problems, please create a new issue.

[peternaf]

python -m pip install git+https://github.com/nficano/pytube

Didn't solve the issue for me, my video is: https://youtu.be/IQ_-PVPtIlI

[tfdahlin]

@peternaf I'm not having any problems with that URL. If you're still having problems, please create a new ticket with the full traceback

Re-run the install command and it seems to be downloading now. Thanks!

@ieshaan12 your video is working on my side. uninstall pytube and install it again and see if it resolves it
