user agent bug

[Jamie-Landeg-Jones]

ok, not exactly serious, but you have the user agent as Gecko/20100101

i.e. 2010 instead of 2011 !!

Also still shows Firefox/4.0b11 though Firefox/4.0b12 is now installed.
Mozilla/5.0 (X11; Linux x86_64; rv:2.0b11) Gecko/20100101 Firefox/4.0b11

[bat999]

Edit
The Gecko 2010 fault might not be caused by youtube-dl because www.browserspy.dk also shows my browser user agent as 2010 too:-
Mozilla/5.0 (X11; Linux i686; rv:2.0b12) Gecko/20100101 Firefox/4.0b12
Though browserspy does show Firefox/4.0b12 correctly.

oh! Weird. Definitely a bug, but not a youtube-dl bug then, sorry! (which rightly 'emulates' the browser)

My firefox shows Mozilla/5.0 (X11; U; FreeBSD i386; en-US; rv:1.9.2.13) Gecko/20110125 Firefox/3.6.13

[bat999]

Edit again.
Hi
There is a reason why Firefox-4 shows UserAgent year 2010 instead of 2011.

eeek, thanks... that explains it.

I didn't realise it was the build date, I assumed it was the date of the gecko release..

nasty bit of info to include for those of us who do source builds!

cheers for the detailed reply

About the beta 11/12: when I released the latest youtube-dl version, I was using beta 11. Beta 12 hadn't made it yet to my distribution repositories. I literally copied the user-agent string from the browser I was using at the moment.

[bat999]

OK
I think that I understand now.
We are using a Mozilla header for youtube-dl so that YouTube thinks it's talking to a browser, not to a download program.
When we use the "--dump-user-agent" command it just tells us which header we are using. It doesn't tell us which browser we are using.

It's here in the code at line 40:-

std_headers = {
'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64; rv:2.0b11) Gecko/20100101 Firefox/4.0b11',
'Accept-Charset': 'ISO-8859-1,utf-8;q=0.7,;q=0.7',
'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,/*;q=0.8',
'Accept-Encoding': 'gzip, deflate',
'Accept-Language': 'en-us,en;q=0.5',

}

Yes, it's just the header youtube-dl sends, to mimic a web browser.

Currently it seems that all you need is the cookies and the url, but it's a good idea to have these to 'fly under the radar' !
