• Refactored @-options handling to save bytes.

  Refactored @-options handling to save bytes.
  If an option is set to @, the global option of the same name as the key
  
  will be used, e.g. :
  
  acceptFileTypes : '@', // acceptFileTypes
  If the options set contains a property prefix, the global options key
  
  will be the prefix plus the option key, concatenated in camel-case
  
  spelling, e.g. :
  
  prefix : 'loadImage',
  
  acceptFileTypes : '@', // loadImageAcceptFileTypes
  If the prefix is set to true, the action of the options set will be
  
  used as key.
  

• Trolls in trouble

  6 juin 2013, par Mans — Law and liberty

  Life as a patent troll is hopefully set to get more difficult. In a memo describing patent trolls as a “drain on the American economy,” the White House this week outlined a number of steps it is taking to stem this evil tide. Chiming in, the Chief Judge of the Court of Appeals for the Federal Circuit (where patent cases are heard) in a New York Times op-ed laments the toll patent trolling is taking on the industry, and urges judges to use powers already at their disposal to make the practice less attractive. However, while certainly a step in the right direction, these measures all fail to address the more fundamental properties of the patent system allowing trolls to exist in the first place.

  System and method for patent trolling

  Most patent trolling operations comprise the same basic elements :

  1. One or more patents with broad claims.
  2. The patents of (1) acquired by an otherwise non-practising entity (troll).
  3. The entity of (2) filing numerous lawsuits alleging infringement of the patents of (1).
  4. The lawsuits of (3) targeting end users or retailers.
  5. The lawsuits of (3) listing as plaintiffs difficult to trace shell companies.

  The recent legislative actions all take aim at the latter entries in this list. In so doing, they will no doubt cripple the trolls, but the trolls will remain alive, ready to resume their wicked ways once a new loophole is found in the system.

  To kill a patent troll

  As Judge Rader and his co-authors point out in the New York Times, “the problem stems largely from the fact that, [...] trolls have an important strategic advantage over their adversaries : they don’t make anything.” This is the heart of the troll, and this is where the blow should be struck. Our weapon shall be the mightiest judicial sword of all, the Constitution.

  The United States Constitution contains (in Article I, Section 8) the foundation for the patent system (emphasis mine) :

  The Congress shall have Power [...] To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries.

  Patent trolls are typically not inventors. They are merely hoarders of other people’s discarded inventions, and that allowing others to reap the benefits of an inventor’s work would somehow promote progress should be a tough argument. Indeed, it is the dissociation between investment and reward which has allowed the patent trolls to rise and prosper.

  In light of the above, the solution to the troll menace is actually strikingly simple : make patents non-transferable.

  Having the inventor retain the rights to his or her inventions (works for hire still being recognised), would render the establishment of non-practising entities, which most trolls are, virtually impossible. The original purpose of patents, to protect the investment of inventors, would remain unaffected, if not strengthened, by such a change.

• FFMPEG video (mp4) to image sequence with the time in the filename [closed]

  7 juin 2013, par Ewald Bos

  i have a question and can't find the answer perhaps you can help ?

  I am using FFMPEG (windows enviroment) and convert a video (mp4) to a series of images based on scene detection (i-frames) and add the timecode inside the image (burn) like this ;

  ffmpeg -i video.mp4 -vf "drawtext=fontfile=trebucbd.ttf: timecode='00\:00\:00\:00': r=25: x=(w-tw)/2: y=h-(2*lh): fontcolor=white: box=1: boxcolor=0x00000000@1, select=eq(pict_type\,I)" -vsync 0 -an iframes/%06d.jpg

  All this works perfect but i also would like to add the timecode in the filename, so instead of naming it 000001.jpg, 000002.jpg i would like to have 00.00.00.01.jpg, 00.00.00.17.jpg and thoughts about this ?
