Unable to download videos M101J

[przemyslawpluta]

I've tested latest version on *nix, os* and win* against all currently available courses and I can't replicate the issues you're seeing.

Unfortunately I don't have access to M101J.

Error seems to indicate issue with python or error on YouTube's site. I'd suggest reinstalling latest version of python and update to the latest version of mongo-edu and to try again.

[professorxuk]

Thanks for speedy response. I'm using latest mongo-edu package v0.1.34, but I'll try v2.x python instead.
Just found this which sounds promising ytdl-org/youtube-dl#1170
But where would I be able to add the --no-check-certificate option ?

[professorxuk]

same error with Python v2.7.8 :(
I am seeing same error response as in ytdl-org/youtube-dl#2540

[przemyslawpluta]

To run mongo-edu with --no-check-certificate flag enabled just add --ncc.

Just tested the https://youtu.be/8q2GB3QSBSI and I can download it just fine without any errors with the default mongo-edu options.

[professorxuk]

--ncc option had no effect.
I have both VirtualBox and VMWare installed - could these be interfering with resolving the youtube urls , although theres no problems via web browser ??

Do you experience similar issues with other courses?

[professorxuk]

my first course I'm afraid

[przemyslawpluta]

Sign in for any other course still available and try to test if you can download any videos.

[professorxuk]

no other courses active at the moment on mongodb uni :(

[przemyslawpluta]

You should be able to sign in into other courses that are already live.

[professorxuk]

My mistake, there was one other course. Just registered and tried M101P but still same result.

[professorxuk]

I'm a complete noob when it comes to node.js ; is there any way of getting a more verbose output (assuming that python isn't at fault) ? proper logging etc

[przemyslawpluta]

As you experiencing the same issue with the other course as well it looks like there is an issue on your system as I can't replicate this behaviour so far.

It seems to be related to python or youtube-dl. Are you running mongo-edu on win7 or on virtualbox/vmware? Is your access via home / work network / proxy?

[professorxuk]

win 7 64 bit via cmd;
I had problems with corporate proxy and was running at home with direct connection.
The laptop is work related so I'm going to try on personal desktop I have (also win 7).
I'm beginning to think that this issue is permissions related.
Should I need to run cmd as Administrator ?
Does node require special privileges?

[przemyslawpluta]

Give it a go and run cmd as admin also try on the personal laptop as it looks like there might be some issues with the corporate proxy. Obviously read/write rights are required as you download and save files locally.

[professorxuk]

I think my DNS server is not handling the mangled youtube URLs. Is there some way to get the proper URLs where there isn't a dot between the u and b ??

Also the log file npm-debug.log is only generated sometimes which doesn't make sense, is there a way to enable this permanently?

[professorxuk]

Installed and downloaded without a hitch on my desktop. It must be some network/permissions problem on my work laptop (probably the latter) that python is unable to get around. I think this issue is fairly common, all relating to youtube-dl, but after a lot of googling I can't find anyone who's solved it...
e.g.
ytdl-org/youtube-dl#2219

[przemyslawpluta]

Cool. Thanks for the update also bump it to v0.1.35 this fixes progress bar issues.

[professorxuk]

I thought I solved it after posting the issue against youtube-dl ytdl-org/youtube-dl#3725 (python was still using my corporate proxy settings) but found that the proxy and verbose options don't seem to have any effect when running mongo-edu. I've been running it like this:

node mongo-edu --cw -d videos

and with extra options (but no difference)

node mongo-edu --proxy "" --cw -d videos --verbose

working directory is APPDATA\npm\node_modules\mongo-edu\bin
Why can't I pass in the python arguments ?

[professorxuk]

Good news is that I got it working now on the laptop. I had to disable my LAN proxy server option. Seems so obvious now!
Accepting the extra arguments would be very useful though but I'm not sure if this is a node.jas issue or a mongo-dl issue or perhaps node-youtube-dl.
