Help would be most appreciated

[Jean-Baptiste Kempf]

VLC version ?

[Trase]

I am encountering this exact problem with version 1.1.1 on Windows 7 x64. Any assistance would be appreciated.

[IamZombie]

I also have the same problem, I just updated to 1.1.1 tonight.

I received the error with v1.1.1 on winxp-sp2
I then reverted to v1.1.0 and got a similar error.

[TekkersT]

So its not just me then , i wonder what's changed for this to stop working , i was really enjoying using vlc rather than listening to sometimes inaudible videos on youtube

[TokyoAussie]

I have exactly the same problem. The main thing that looks different to me at first glance is that the slash characters in the source URL in media information are being escaped by backslashes. i.e. "http://www....." becomes "http:\/\/www..." and that would be enough to throw off the URL (so the file cannot be found). Why this happens is a mystery to me. At least I don't remember seeing those backslashes before.

I was mucking around when this all started. Sometimes a file would play, then not. Now it is a firmly will not play at all. This is one of my major uses for VLC so I am hoping for a quick fix soon.

[TekkersT]

VLC version ?

The latest version .

Have you any idea what the problem is ? im not very technical , its worked fine everytime for me then all of a sudden it stopped working completely

Maybe youtube changed something ?

If you look at the source for any youtube page, they escape the backslashes also. I don't know if they always did, but currently they do, so out of hand I don't know if that's the main problem.

Maybe youtube changed something ?

That's the most likely scenario. The only think we can hope for is vlc to change the way it parses and reads URLS from youtube pages, to fix it again.
But there is nothing stopping youtube from breaking it again.

[Rémi Denis-Courmont]

YouTube changed the page layout. You need to update to VLC 1.1.1-15-gebd7e0c or later.

[TokyoAussie]

Update solves some issues, I presume, but Youtube issue is not one of them (at least not on mac).

[TekkersT]

Update solves some issues, I presume, but Youtube issue is not one of them (at least not on mac).

yeah iv got the latest and still cant watch youtube videos also

[Rémi Denis-Courmont]

For people with vision problems, I will state it a second time in larger letters:
You need to update to VLC 1.1.1-15-gebd7e0c or later.
Obviously, if you have VLC 1.1.1, it is not going to work.

who do you think your posting to ? why so arrogant ? wtf is your problem ?

we are here asking for help !!! if you cant help then you best go away . never in my life have i read such an ignorant response .

What a horrible person and unhelpfull character .

absolutely stunned here , all i wanted was help and all i got was patronised , incredible

[etn]

I haven't found it yet either, however, I think you two guys who are being so rude should take that elsewhere.

You probably would've gotten a lot more help if you had nicely asked for a link.

His only reply was to yell that we need to upgrade to some unreleased/non-public version.

Forum rules
Be polite when posting, and please refrain from using insults or other abusive language.
Don't use ALL CAPITALS EVERYWHERE or very big text or a lot of color in your posting. This is considered to be highly annoying and will most likely result in no one answering you.

I haven't checked the nightly builds status, but it should be in.

What help?
His only reply was to yell that we need to upgrade to some unreleased/non-public version.

No. My response was to point that out. Then when another two people completely ignored the response (not even bothering to ask clarifications, you know), I wrote the same thing again in larger fonts. And, for those who don't understand version numbers, I even added that, well it is more recent than 1.1.1.

And no big news here. When a bug is fixed in the latest develoment version, the bug is fixed. Over. That's how our bug tracker has worked for years, and that's how the whole software industry works internally. This is especially true for open-source: http://git.videolan.org/?p=vlc/vlc-1.1. ... 211e535e66

The project simply cannot make a full blown release for every fix that is delivered (I count already 220 individual changes since 1.1.0). And even if we could, what do you guys would think if we had the auto-update kicking every 4 hours (220 changes in 35 days), and how do you think the download servers would cope?

2. Open it with a text editor.

4. Save the file.

That's all.

[Anfe]

Thanks kovezett.
I've changed the youtube.lua file and now it works.
I can watch youtube videos on VLC.

[IamZombie]

OK, thank you for the help, I can now view youtube videos in VLC.

Now how do I save them?
If I convert them, all I get is a ~200 byte file.

I'm trying to save just the audio from a video.

[vilapupu]

OK, so I was getting this problem today, so instead of making a topic about it, I just tried looking it first if the bug was reported and saw this. ^^
did the youtube.lua file thing and it worked! ^^
Now, I did this differently since I have Windows Vista so I will tell on how I did it:

1st was to look for the file. I just pressed on Start, then "Computer", then to "Local Disk (C:)" and then I copy and pasted ' youtube.lua ' in the top right corner of the screen. (for quick results, go to the "Program Files" folder when searching the " youtube.lua ".

2nd was to Open the youtube.lua file with WordPad. then I just deleted everything in the document and copy and pasted all from the new text that was posted here

3rd was that Before saving, to Right-click the file 'youtube.lua' and press on "Properties". Then from there I went to the "Security" Tab, clicked on "Edit", press on Continue to the pop-up window, and then checked the "Full Control" in 'User' (will say your username of your PC) and clicked OK.

4rd was the simplest one and it was to go back to the WordPad Document and click on "Save". and close it.


Hope this was useful for Win Vista (and probally Windows 7 users) to not get the "access denied" or "can't save" message when editing "youtube.lua" in Wordpad or in any other text editing program.

[migawka]

hi, can someone change the youtube.lua code to force VLC to play higher quality videos 480p? thanks

You can add fmt switchers to the URL:

MPG: add &fmt=18

http://www.youtube.com/watch?v=Yy2uHAS-el0&fmt=18
