Troll spirit
15 juin 2013, par Mans — Law and libertyLast week’s announcements from the White House of steps being taken to begin fighting back against patent trolls, along with legislation passed in Vermont for the same purpose, are worthy of praise. Whether they prove effective or not, they are a sign of the problem finally having been recognised by the highest authorities. That said, only one aspect of the issue is addressed, that of non-practising entities or trolls. Little effort is being made to stymie troll-like behaviour from otherwise legitimate actors. While a stake is driven through the heart of the troll, its spirit remains free to roam the corporate world, and like a demon of darkness it possesses companies, compelling them to engage in the very practices we seek to eradicate.
The demon
The most damaging, when wielded by a troll, are those patents with vague or overly broad claims. These can easily be asserted against large numbers of alleged infringers, many of which likely choose to settle out of court rather than risk an expensive litigation process with uncertain outcome. Such negotiations are frequently subject to non-disclosure agreements prohibiting publication of details in any deals, or even the existence thereof. As a result, an accused has no way of assessing a fair price for a licence (assuming the patent is in fact valid), and the patent holder can thus extract from each would-be infringer precisely as much as they are willing or able to pay to avoid a lawsuit.
At the root of this problem is the ease with which applications for the patents in question are granted. Given the volume of patent applications, it is hardly reasonable to demand a hugely more extensive examination process than currently takes place (although some improvements here are no doubt possible) ; after all, a speedy decision is in the best interest of all parties. The solution must evidently be found elsewhere.
The exorcism
An obvious cure to the problem is the abolishment of the patent system. As this is clearly not feasible today, more practical, albeit less effective, remedies must be sought. A few ideas follow.
- Make patent validity all or nothing
- Change the rules such that any claim being found invalid cancels the patent its entirety. With the full patent at stake in this manner, companies would be discouraged from gambling on frivolous claims and encouraged to conduct a more thorough background investigation before filing.
- Maintain a registry of licences
- Require that all patent licence agreements be filed in an open, easily searchable registry. This would hopefully increase fairness in licensing deals.
- Mandate reimbursement of licence fees for invalidated patents
- If a patent is challenged and found invalid, require that the owner reimburse any licence fees previously collected for the patent in question. Apart from being morally right, this could act as a deterrent to over-charging. The amount requested for a licence would likely be balanced against the risk of being made to pay it all back later, resulting in lower licence fees for low-confidence patents.
These suggestions, alone or together, will not completely eradicate the problems of patent abuse. They are but small steps towards a more thorough overhaul of a system increasingly ill-suited to the nature and pace of modern technological development.

FFMPEG - Merging Videos with Transparency
4 juillet 2013, par user1829136I am trying to merge two videos together, both have transparency, using the command
ffmpeg.exe -i person2.mov -vf "[in] scale=iw/2:ih/2,fade=out:300:30:alpha=1, pad=2*iw:ih [left] ; movie=person2.mov, scale=iw/2:ih/2,fade=out:300:30:alpha=1 [right] ; [left][right] overlay=main_w/3:0,fade=out:300:30:alpha=1 [out]" -b:v 768k Output_people.mov
By doing that I get the following output :
http://i263.photobucket.com/albums/ii122/Fernando461/Untitled.png
As you can see, it was possible to get the two videos to be on top of each other. But then, when I try to merge this video (Output_people.mov) with another video, it doesn't have the same transparency. Is it possible to keep transparency in the outcome ?
Edit 1 :
This is the output I get : https://www.dropbox.com/s/gpid1pptfio31gd/ffmpeg-20130701-193206.log
And by "it doesn't have the same transparecy" I meant that the background is black instead of being transparent, so if I put one video on top of each other, the one in the back is covered by a black part of the one in the front.
Edit 2 :
Adding -vcodec qtrle to the code worked. Thanks mark4o ! -
