Description

youtube-dl will properly download YouTube videos, but the [-g] option spits out URLs to different videos. Wget, cURL, and mplayer download the wrong video. Behaviour does not vary when changing user-agent in any four (or any combination of the four) programs.

Most youtube links will result in the same video being downloaded (https://www.youtube.com/watch?v=5mPDhmP6ztQ). Behaviour happens across several machines (32 and 64 bit) at different addresses.

Minimal test program

!/bin/sh

BAREURL="$( youtube-dl -g '$1')"
wget "$BAREURL"
exit

How are you calling the script?

The script works fine for me from the US.

Can you define wrong? Is it another video? Is it random data?

Does the problem occur when you use youtube-dl's built-in downloader, i.e. do not pass in -g? What output do you get if you pass in the -v option instead of -g?

Can you reproduce the problem with http://www.youtube.com/watch?v=BaW_jenozKc ?

it downloads https://www.youtube.com/watch?v=J0-rgeU1E4w

This script works fine:

#!/bin/sh
BAREURL="$( youtube-dl -g "$1")"
wget "$BAREURL"
exit

@phihag Maybe we should disable the automic search by default and let it fail.

Calling the aforementioned script 'test.sh' and performing

./test.sh 'https://www.youtube.com/watch?v=yrBrH5PZtcc'

will result in downloading the YouTube video https://www.youtube.com/watch?v=5mPDhmP6ztQ. The URL youtube-dl spits out is:

The same behaviour happens on the test file at http://www.youtube.com/watch?v=BaW_jenozKc : youtube-dl spits out a googlevideo URL that points to another video (the same damn "TrapDoor" video at https://www.youtube.com/watch?v=5mPDhmP6ztQ).

In comparison, performing

youtube-dl 'https://www.youtube.com/watch?v=yrBrH5PZtcc'

will download the correct video (https://www.youtube.com/watch?v=yrBrH5PZtcc - "Opeth- Demon of the Fall-yrBrH5PZtcc.mp4").

Motivated by an earlier youtube-dl issue, I've tried removing ~/.config/youtube-dl/. It did not change the behaviour. The strace is non-distinct...

Forgot to mention that this is intermittent.

Here is the verbose info you requested. Nothing fishy happening when youtube-dl handles the download itself.

Hmmm.... maybe there is something strange with my machine. (Or maybe YouTube is playing with me?) Forgoing the script seems to work at the moment:

seems to correctly download the test file. And the first example from my last post appears to work now too:

I'm not sure what the issue is, but I seem to be the only one having it. I'll close for now and open again when (if) I can get a better handle on it.
