Youtube video download slow #30583
Comments
|
YT made the client solve a puzzle in order to get full download speed. We can do that now (again, after YT broke it last night) and an imminent release will fix it. Or you can install from the git HEAD using pip, but as you're using the Windows .exe probably you should wait for the release. |
|
This issue also happened to me. using the last update, the download stuck at 74.93KiB/s Good luck team. |
|
Yeah I was also getting this issue.. Previously it was running fine, now something wrong may be happened with youtube.
|
|
Using the "fixed" version of the youtube.py, works now, but there is a problem. @dirkf Should i open a different issue with this? |
|
The results are supposed to be cached. In my original version, I had a local per-item memo so the descramble was only done once. This version is meant to use the player cache as in yt-dlp. You can see that it does so with I've only tested it on a scrap laptop (OK, I upgraded the CPU to T7700 2.4GHz) and I didn't see anything unusual. Equally I didn't Would you be able to try your playlist against yt-dlp as well, or reveal the URL anyway? |
|
I use it like a library in an app, so I can't use UPDATE: I couldn't make the older cashing code to work with the current changes. |
|
The code uses the IV S/t like this: Here I'm assuming you have a different |
|
That was a nice idea, but unfortunately it produces an error: |
|
This says fixed but I am getting 526 B/s downloads - slower than if I watched the video! Realplayer download works at 10 MiS but not what I want. I tried with both youtube-dl and yt-dlp both running that slow. |
The master version in the yt-dl repo is fixed. The fix is not in a released version yet. yt-dlp release 2022.02.04 should run unthrottled. |
If you can make a small program that reproduces the problem, we might be able to make progress. |
Unfortunately, I use Any already existing, simple threading example, will be greatly appreciated.. P.S. The updated extractor has the same results.. 😢 |

FYI: Followed advice regarding pulling from 'master'.....
For those wishing to build, here's what I did ( for better or worse & whether correct or not... ): MAKE SESSION/git/youtube-dl$ make LS YOUTUBE-DL-rwxrwxr-x 1 god god 1849986 Feb 9 01:00 youtube-dl FAST DL SPEED[download] 100% of 51.86MiB in 00:04 |
|
Yeah very fast download speed !!
|
|
If anyone has a Python installation with a recent pip (pip3), you can install the latest master branch (or any other commit level) directly from GitHub or a downloaded tar.gz. |
|
Tested the current latest master with the example above, and the time got improved from 96 to 76 secs. |
|
As a temporary fix you can use Aria2c external downloader to get split file downloading and/or batch file downloading, effectively removing throttle issues. |

The fix committed to the repo requires more than one file to be updated. @TagAcheron, #30583 (comment), or install Python and #30583 (comment). |
|
@dirkf Yes, I already had that update. |
Building and replacing the binaries, worked for me too |
