    "'DVD Jon' Breaks Google Video Lock

    Johansen, also known as 'DVD Jon' for his work on decrypting DVD security codes, has created a patch for the Google Video Viewer--less than 24 hours after the search giant shipped the video playback plug-in, a tool based on the open-source VideoLAN media player.

        A little-known hacker secret known as "//" or comment sequence is being used to illegally remove protections in computer software

        "It's a nightmare for the industry, the // sequence is being used to defeat protections in hundreds of thousands of software programs, costing the industry trillions of dollars in lost revenue" said Robert Holleyman, president of the Washington-based Business Software Alliance (BSA).

        While Linus Trovalds confirmed that the // sequence may be a powerful tool for removing protections, he downplayed the threat, stating that only software for which the code is freely availble can be cracked using the method.

        Various anti-piracy groups are pressuring congress to pass an extention to the DMCA laws, which will effectively outlaw commenting out parts of computer code. Under the new law it will also be illegal to manufacture a computer keyboard with the forward slash '/' key.

    Ryan Naraine - PC Magazine Tue Jun 28,10:49 AM ET

    Norwegian hacker Jon Lech Johansen has cracked the lock on Google's new in-browser video player.

    Johansen, also known as 'DVD Jon' for his work on decrypting DVD security codes, has created a patch for the Google Video Viewer--less than 24 hours after the search giant shipped the video playback plug-in, a tool based on the open-source VideoLAN media player.

    The patch, released on Johansen's 'So Sue Me' blog, effectively disables a modification Google made to the VideoLAN code to prevent users from playing videos that are not hosted on Google's servers.

    Johansen said the patch, which requires the .Net run-time framework, will remove Google's restriction and allow the playback of video files that aren't on the video.google.com server.

    The 21-year-old hacker, who faced two trials in Norway in 2002 and 2003 for his role in the release of the
    DeCSS decryption software, is a hero to many for his efforts to defeat DRM (digital rights management) mechanisms built into media player technology.

    He has been involved in a public cat-and-mouse game with Apple Inc., releasing several tools to bypass the DRM software used to encrypt music sold on the iTunes Music Store. LINK TO: PyMusique Unlocks iTunes Copy Protection. Again. http://www.extremetech.com/article2/0,1558,1779526 ,00.asp [extremetech.com]

    Johansen has also cracked Apple's AirPort Express's encryption and released a proof-of-concept program that allows
    Linux users to play video encoded with Microsoft's proprietary WMV9 codec. The proof-of-concept is based on the VideoLan code.

    Addict3d.org more details:

    Jon Lech Johansen, "DVD Jon", took just one day to build a crack to allow you to play video on your website using Google's VLC-based player.

    This means you can publish video that will play on your webpage and will work for anyone who has Google's player installed.

    Johansen, also known as 'DVD Jon' for his work on decrypting DVD security codes, has created a patch for the Google Video Viewer--less than 24 hours after the search giant shipped the video playback plug-in, a tool based on the open-source VideoLAN media player.

    Crack can be found here -

    http://nanocrew.net/wp-content/GVVPatch.exe [nanocrew.net]

    http://nanocrew.net/?p=114 [nanocrew.net]

    Blog Entry:

    Google has released Google Video Viewer, a browser plugin based on VLC. Here's one of the features they've added:

    + // Google mods
    + const char* allowed_host = \"video.google.com\";
    + char * host_found = strstr(p_sys->url.psz_host, allowed_host);
    + if ((host_found == NULL) ||
    + ((host_found + strlen(allowed_host)) !=
    + (p_sys->url.psz_host + strlen(p_sys->url.psz_host)))) {
    + msg_Warn( p_access, \"invalid host, only video.google.com is allowed\" );
    + goto error;
    + }

    This "feature" prevents you from playing videos that are not hosted on Google's servers. Download and run this patch I wrote to remove this restriction. Running the patch requires a .NET runtime.

      That part is highly misleading! The people who want to view video on your website each individually need to download the patch! It's not very useful to content providers with this restriction.

      How about users? Who would download this patch? Well, people who want to watch videos tagged with application/x-google-vlc-plugin that aren't from google. Not too many of these...

      I'm disappointed by Google's use of the 'goto' keyword. As was clearly described in this paper [acm.org], the use of 'goto' leads to "swiss-cheesing" of the brain, the inability to think logically, and a plethora of other problems, leading eventually to brain-rot and inability to write code in anything but Perl.

      I think we should all remember that just because Google is the pinnacle of success and is second only to (insert your diety here), Google too can make mistakes.
      • by Anonymous Coward
        He in fact ends his paper by saying that goto is not to be avoided at all costs, in fact quite the opposite.

        "The exercise to translate an arbitrary flow diagram more or less mechanically into a jump-less one, however, is not to be recommended. Then the resulting flow diagram cannot be expected to be more transparent than the original one. "

        You have to understand when he wrote that paper people were doing what we would do know as while loops and switch statements with goto. He was arguing for alternatives
      • my C programming prof in college told us he would fail anyone who dared use a "goto" in any program during his class. I could tell he was serious because hte more he talked about it the angrier he got. It got to the point to where he was basically yelling at the class about how we better not use a goto. He was an industry guy turned prof so I guess he must have had a bad experience or something.

        ### I'm disappointed by Google's use of the 'goto' keyword.

        While goto is often better avoided, a call like "goto error;" is among the perfectly valid uses of goto, since it actually can make code more clear and logical then code without goto. Such use of goto is really no different then exceptions in C++, simply a way to get to the place that handles the error conditions without having to painfully drag error-variables through the code.
    • Let's see, he uhh..

    So, in other words, he modified the source code, which was being distributed. They didn't attempt to obfuscate that they didn't allow it from other hosts. They didn't entangle the code or anything. The code was wide open.

    In other words, big friggin deal. All you had to do was grep the code of an error message and a little snipping of the code. Any fool could have done it. Or even screw that, it was domain-based. Setup an HTTP server, modify your hosts file to alias "video.google.com" (or whatever the domain was) to 127.0.0.1, and you're done. Or just modify VLC to know the MIME type "application/x-google-vlc-plugin" and you can play your heart away.

    What "crack" will he do next? Take the VLC code to dump the file/stream you're playing, add it to Google's code, and create a Google Stream Ripper? Wow... how... amaz... ing. Or maybe add some awesome skins to the Google player? Yeah, that'd be great. Best part of all, he'll do it in 48 hours, while standing on his head, without sleeping, pizza, or coffee, and while playing the banjo!!!

        I think you make a very good point. This is perhaps more of an example of Google "doing no evil", creating a tool that, by default, for most casual users, promotes their video feed, while at the same time using a good free software project that allows those who want to, to bypass this setting.

        If most people find the restriction onerous, they'll download a patched version (probably from websites that are also offering video). Social and market dynamics can take care of the rest. It seems a fairly reasonable position for Google to take ("we'll try this restriction, and if people really find it offensive, they'll modify the source and outcompete our offering, and we can write it off to experience and not try imposing these sorts of restrictions again. Either way, it probably won't affect our video feed business much.")

        I doubt very much it is incompetence--google has much of the best talent around--nor is it a lack of understanding opensource/free software on the part of google, as they've been active in the community for many years.
      • Perhaps even "We here at google have applied Jon's patch to the code and agree it's an improvement, so we'll be leaving it this way for all users"?

        That might take the hot air out of Yahoo's sails.

    If you check out the blog, you'll see that there's a nice goto at the end of the if statement.

    Supposedly Google only hires top-coders, so what's up with that?
    • goto when used correctly can simplify code and make it easier to read.

      Most colleges just say never use it because so many people turn out horrible code by using too many or misusing the goto statement.

    • Nothing's up with that. One of the cases where goto works nicely.

      Of course, there's no reason to believe that Google only hires "top-coders" but this isn't evidence to the contrary.
    • Good programmers know goto is harmful - great programmers know when it's not.

      Actually, even there I'm exaggerating a bit. Even fairly average programmers can usually be taught when goto is acceptable and when it's not. Anyway, the goto statement in C is much more limited, and much safer than the wide-open, global-scale thermonuclear goto that Wirth originally wrote about.

  • Seriously, does Jon have to do it all? If some states AG gets a burr under his saddle about something like this, they can again incarcerate him and cost him a boatload of sheckles to get clear of it.

    My point is, why does it always have to be 'DVD Jon' that does it, the more contributions by others the merrier the party.

    And this comment from a 70 year old who really ought to be more of an 'establishment' type.

    Realisticly, both patent and copyright has been expanded to protect the guilty until even I can

    From Google's patch to VLC:
    - uuid(E23FE9C6-778E-49D4-B537-38FCDE4887D8),
    + uuid(E23FE9C6-778E-49D4-B537-38FCDE4887D9),

    A little offtopic, but who gets to decide these things, to prevent clashes? What's their purpose anyway?

    Did anyone notice the entire Matrix Revolutions is available there in Google Video? Pretty cool. You might think it's just 30-second clips, but hit "Play whole video" and off it goes. Whole movie. Wondering if this is a special "show-off" case google snuck in, or a black-hat's upload?

    see this link [google.com] for the video

    Um, the entire collection of the Travel Channel's Great Hotels?

    The O'Reilly Factor?

    The Tony Danza Show?

    C-SPAN Book TV?

    Is this stuff being provded by the TV studios?

    What is the deal with Google Videos?

    Where is all the content coming from?
