downloading video from youtube

i want to download at http://www.youtube.com/watch?v=J5f-jUpUp8o
the video does not get cached in firefox.
if you are able to grab this video. please tell me how ?

Install youtube-dl, then just:

Code:

youtube-dl -t http://www.youtube.com/watch?v=J5f-jUpUp8o

You could also install Firebug, a firefox add-on.
Open Firebug (F12)
Click on the network tab and click enable when you get to youtube.
Load that video.
Reorganize the data transfers by size (the video will be the largest between ~50-100MB).
Then copy the URL into a new tab and save file as.
Alternatively, you could install DownThemAll and download the video spoofing the referrer from the DTA Manager.

If the video doesn't show up it means you didn't enable Firebug in time to capture the network transfer. Simply clear your cache and then reload the page after Firebug is open and network is enabled. You should see it then.

The same method works for music sites like playlist.com. It's not illegal to download music that way because you're following the DMCA and not sharing music, only downloading publicly available music.

@macemoneta: That's a cool script. First time I've seen it.

i've noticed the 'net console allows you to locate the url of online radio streams from sites like live365 as well (something they USED to publicly publish when i first became a member)

It's in the Fedora repository, and they keep it up to date which is why I use it. It hasn't failed me ... yet. :)

i used https://raw.github.com/rg3/youtube-d....04/youtube-dl
i got this output

Code:

./youtube-dl -t http://www.youtube.com/watch?v=J5f-jUpUp8o

KeyError: 'url'

That video appears to be protected (probably DRMed).

sumeet inani,

I use the Firefox add-on Video DownloadHelper: https://addons.mozilla.org/en-US/fir...ownloadhelper/ . It works well and will convert video formats as it is downloading, if you wish.

Hope that helps.

hi jmszr,
actually video link i pointed out seems difficult to grab.
please explain your success in this case.

from youtube-dl documentation

Quote:

Some YouTube videos are served using Adobe's proprietary RTMP protocol, which imposes DRM restrictions and encrypts the connection. youtube-dl is not able to download these videos by itself. However, it will attempt to use the rtmpdump program, if it's installed in your system, to download these videos.

i could not compile rtmpdump & could not find debian file.
i am using ubuntu 10.04

i have installed libssl-dev
here i am stuck

Code:

while in latest git

It doesn't matter. I built the latest rtmpdump from git and applied the latest patch to youtube-dl. That file now generates:

Code:

$ ./youtube-dl 'http://www.youtube.com/watch?v=J5f-jUpUp8o'

ERROR: rtmpdump exited with code -11

You'll have to wait until one of the developers figures out what changed.

can you solve my rtmpdump installation ?

You need to install the 'glibc-devel' package for POSIX threads (on Fedora).

Which OS are you using ? Please specify OS every time you ask a question.
Ubuntu 11.04 ? Fedora 15 ? Etc. etc.

'rtmpdump' compiles OK with gcc-4.4.1 : cd rtmpdump/ && make : No errors.
