|Libav provides cross-platform tools and libraries to convert, manipulate and stream a wide range of multimedia formats and protocols. avconv is a very fast video and audio converter that can also grab from a live audio/video source. It can also convert between arbitrary sample rates and resize video on the fly with a high quality polyphase filter. AVplay is a very simple and portable media player using the Libav libraries and the SDL library. avprobe gathers information from multimedia streams and prints it in human- and machine-readable fashion. avserver is a streaming server for both audio and video. Command line tools.

- ffmpeg deprecated, added avconv, which is almost the same for now, except
for a few incompatible changes in the options, which will hopefully make them
easier to use. The changes are:
* The options placement is now strictly enforced! While in theory the
options for ffmpeg should be given in [input options] -i INPUT [output
options] OUTPUT order, in practice it was possible to give output options
before the -i and it mostly worked. Except when it didn't - the behavior was
a bit inconsistent. In avconv, it is not possible to mix input and output
options. All non-global options are reset after an input or output filename.
* All per-file options are now truly per-file - they apply only to the next
input or output file and specifying different values for different files
will now work properly (notably -ss and -t options).
* All per-stream options are now truly per-stream - it is possible to
specify which stream(s) should a given option apply to. See the Stream
specifiers section in the avconv manual for details.
* In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
sense that they're specified after the output filename instead of before,
like all other options. In avconv this irregularity is removed, all options
apply to the next input or output file.
* -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
irregular and highly confusing, they were also redundant. In avconv the -map
option will create new streams in the output file and map input streams to
them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
each stream in the first input file.
* The -map option now has slightly different and more powerful syntax:
+ Colons (':') are used to separate file index/stream type/stream index
instead of dots. Comma (',') is used to separate the sync stream instead
of colon.. This is done for consistency with other options.
+ It's possible to specify stream type. E.g. -map 0:a:2 creates an
output stream from the third input audio stream.
+ Omitting the stream index now maps all the streams of the given type,
not just the first. E.g. -map 0:s creates output streams for all the
subtitle streams in the first input file.
+ Since -map can now match multiple streams, negative mappings were
introduced. Negative mappings disable some streams from an already
defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
all the stream in the first input file, except for the second audio
* There is a new option -c (or -codec) for choosing the decoder/encoder to
use, which allows to precisely specify target stream(s) consistently with
other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
libvorbis sets the codec for the first audio stream and -c copy copies all
the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
aliases to -c:v/a/s
* It is now possible to precisely specify which stream should an AVOption
apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
-b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
syntax is deprecated and will stop working soon.
* -map_chapters now takes only an input file index and applies to the next
output file. This is consistent with how all the other options work.
* -map_metadata now takes only an input metadata specifier and applies to
the next output file. Output metadata specifier is now part of the option
name, similarly to the AVOptions/map/codec feature above.
* -metadata can now be used to set metadata on streams and chapters, e.g.
-metadata:s:1 language=eng sets the language of the first stream to 'eng'.
This made -vlang/-alang/-slang options redundant, so they were removed.
* -qscale option now uses stream specifiers and applies to all streams, not
just video. I.e. plain -qscale number would now apply to all streams. To get
the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
and -aq is now an alias for -q:a.
* -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
uses stream specifiers. Use -bsf:v/a/s instead of the old options.
* -itsscale option now uses stream specifiers, so its argument is only the
scale parameter.
* -intra option was removed, use -g 0 for the same effect.
* -psnr option was removed, use -flags +psnr for the same effect.
* -vf option is now an alias to the new -filter option, which uses stream specifiers.
* -vframes/-aframes/-dframes options are now aliases to the new -frames option.
* -vtag/-atag/-stag options are now aliases to the new -tag option.

|Post comment
It seems that branch 12 will bot released before I am 6 feet under!
That sucks! LIBAV is not a good choice for developers who wants to be up-to-date!
Your overall better choice is FFMPEG!
Still no branch 12 to see on the horizon!
That makes me tired...
It still does not have proper support for Avisynth 2.6, is a shame.
Simply annoying is the long time between major release versions. Version 12 is under development since more than a half year, but we still see no release version announced. I just complain about it because most open source software developer do not use nightly builds so new features not come to life in proper libav based softwsae tools while ffmpeg based tools have it included due to their faster integration to release versions & the shorter release cycles.
I do not say that ffmpeg is more better than libav or the other way around. I just say that great developments does not cone to life without a force to release it soon. Development in libav is great, but please let it out all the good work you did to can use all the good work in great tools such as VLC Player or Handbrake. If these tools would use ffmpeg libraries the missing features & format support would be already a part of it...
My hope for the future is to see libav & ffmpeg teams joined.
Twelve years ago that Avisynth use, in ffmpeg I have no problems, in mencoder I have no problems, in libav:
"avconv version v12_dev0-1322-g4e17946, Copyright (c) 2000-2015 the Libav developers
built on May 24 2015 18:24:04 with gcc 4.8.3 (Gentoo 4.8.3 p1.1, pie-0.5.9)
C:\Program Files (x86)\LIBAV\usr\bin\LIBRA.avs: Invalid data found when processing input"
Please fix it.
Thank you.

NEW YORK -- Cellphone service and free Wi-Fi have arrived at another 30 New York City subway stations, officials announced Thursday.
The Metropolitan Transportation Authority announced the expansion Thursday of a program that started with six stations in Manhattan's Chelsea neighborhood in 2011.
Phone and Internet service are now available at busy stations including Times Square, Columbus Circle and Rockefeller Center.
"It's a big deal for the millions of MTA customers who pass through these stations every single day," said Thomas Prendergast, the agency's interim executive director. "It means you can check your email, surf the Web, or do just about anything you do upstairs while you're waiting for a train."
Prendergast said rider safety will be enhanced at the wired stations, because "help is just a 911 call away."
The wireless equipment is being installed by Transit Wireless, a subsidiary of Broadcast Australia, with Boingo Wireless operating the Wi-Fi. Cellphone carriers AT&T, T-Mobile, Sprint and Verizon are participating.
"It's going to really change the way we commute on subways going forward," said Tom DeVito, AT&T's vice president for New York and New Jersey, who joined officials from the other companies and the MTA at a crowded news conference in the Times Square station.
All 277 of the system's underground stations should have phone service and Wi-Fi by 2017, officials said.
The cost of $200 million or more will be borne by Transit Wireless and the carriers. Wi-Fi users will see ads that will help pay for the service, said Boingo Vice President Zack Sterngold.
Straphangers said they welcomed the underground service.
"You get down here and you can't make phone calls," said Rick Piironen. "It's kind of a pain, right?"
Vlasios Vlassopoulos said cellphone service would be good for emergencies, but added, "I know a lot of cellphones get stolen and I hope that doesn't increase."
Prendergast said the MTA is working with the police transit bureau to ensure safety, adding, "Proper care should be taken as you do with your wallet and things like that."
While cellphones may be used in the stations, there are no plans for service on the moving trains.

SCRANTON, Pa. — Pennsylvania's Marcellus Shale drilling industry is continuing to post huge gains in production.
The Times-Tribune of Scranton reports that Bradford, Susquehanna and Tioga counties led the way with 260 billion cubic feet of gas.
Energy firms have been boosting their production targets, not only because new wells are coming on line but also because they're managing to coax more gas from each well.
The Marcellus is a rock formation primarily beneath Pennsylvania, New York, West Virginia and Ohio.

Facing felonies, woman misses court date
BARRE A Williamstown woman missed her arraignment Thursday on felony charges she stole her brother-in-laws identity and racked up around $1,000 of debt in his name.
Debra A. Hutchings, 57, is facing charges of false pretenses and identity theft both felonies in Washington County criminal court in Barre. She was supposed to be arraigned on the charges Thursday, but Hastings did not show up.
A judicial summons was issued for her to appear at a later date. If Hutchings is convicted, she faces a maximum sentence of 13 years and a $7,000 fine.
According to the Vermont State Police affidavit, Hutchings brother-in-law, James Papineau, went to the state police in December saying Hutchings had opened up four credit cards in his name.
Papineau gave state police documentation showing electronic checks were issued in his name in the accounts totaling $1,028.29, including overdraft fees.
Papineau told state police Hutchings used a fabricated company, Papineau Meat Cutting, and her own address to open one of the accounts. Papineau said he had done some butchering in the past so he could only assume that is where Hutchings must have gotten the name, according to state police.
When questioned by state police about the accounts, Hutchings admitted to using Papineaus name, Social Security number and a date of birth exactly one year off of Papineaus in order to create the accounts. Hutchings told the state police she had fallen on difficult financial times and created the accounts so she could pay her bills. She told state police she planned to pay the bills off but things escalated and she could not pay off the debt.
State police say they received an email from Capital One, one of the banks where she allegedly opened up a fraudulent account, saying Hutchings had contacted them and had taken responsibility for the debt.MORE IN This Just InPolice: Driver

We asked, and the best fatherly advice (dadvice, if you will) PennLive readers have to dispense is all here (and here)! No matter the occasion or the intent, fathers, father figures and their words have a lasting impact. You can run these past the father in your life for his approval or crib them for use on your own kids, but no matter what, have a happy father's day!
Maintain that work ethic
- Robin Clouser: "My Dad has given me lots of great advise over the years (he is now 85) but this one most often comes to mind 'Hard work never killed anyone"...It hasn't killed me yet!'"
- happycynic: "'Just do your best and I'll always be proud of you.' He was successful in business and politics and I was the prodigal son who left college having only attended music classes,soccer practice, and parties. When I went to my first 'real' job he told me again, whatever they made me do, do my very best. If they ask you to sweep the sidewalk make it the cleanest sidewalk on the block. I thought he was going to cry. Ironically the first thing I was asked to do was sweep the sidewalk! But hey, I kept doing as he said, and within a year and a half I had 3 promotions, was wearing a suit and tie and then was offered my own location selling high-end merchandise. Of course I declined, quit, and went into the music biz...I proved something to him though….Worst day ever was holding him as he passed away. Man, I miss him."
- Josette Plank: "My dad told me to travel the world whenever I had the opportunity. He [also] said, 'If you're finished a job early, ask your boss what more work there is to do.'"
- Dennis_Lohr: "On the day I graduated from high school my dad paraphrased Yogi Berra: 'Some people play the game. Some people watch the game. And some people don't even know what's going on. Play the game.'"
- JJ: "You're never as good as you think you are after you win, and you're never as bad as think you are after you lose."
Be honest
- Edward J. Kramer: "Tell the truth….Once you do, there's nothing else to tell."
- Theresa Fenerty: "Words can have a great impact on someone's life...my dad's best advice...'Say what you mean and mean what you say.'"
- Robin Edwards: "'Your friends can get you in more trouble in one day than you can get yourself into in a life time.'"
On parenting
- Elena Damrauer: My beloved father passed away on May 11, 2010 of metastasized bladder cancer. The very last coherent conversation he and I had was the Sunday before he died. It was Mother's Day and I'm the mother of his first grandson. I told him that he was the best father that I could have asked for, that it was from him that I learned my parenting skills, and that without him I wouldn't be who I am today. He wiped away a tear and said to me 'Kiddo, (He ALWAYS called me kiddo) just be happy and you'll have everything.' Best. Advice. Ever."
- Chuck Kish: "The older you get the more intelligent your parents become"
- robo80: "The best fatherly advice I ever received was nothing, because I was never given advice; however, that ended up giving me the best life lesson to pass on to my (now 4 year old) daughter. When she was born promised to not be absent like my own father. I could have used it as an excuse to continue the circle of neglect, like a lot of criminals you read about, but I used it as an example of a father I did not want to be. Sometimes we figure out who we want to be by defining who we don't want to be, and my daughter seems pleased with the end result of the lack of advice I received."

- rampboss: "Pull and pray..."
Tough love

- Wendell V. Courtney: "In my first golf tournament as an 8th grader, I finished in 2nd place and when I proudly showed my father the trophy I had won for 2nd place, he said, 'That's nice son, but nobody ever remembers who finished in 2nd place.'"
- Scott Cooper: "Do not know how to say is cleanly but the best advice my father ever gave me was 'don't be an a******.'"
- limited-edition: "It was never anything he said, it was what he did....He got up every day and went to work. As it turns out it was the best advice and the worst advice all rolled in to one."
- roughage: "My Dad used to tell me 'no matter how smart you are, you will never be as smart as me. And when you realize that, is when you will be getting smarter!' Luckily I was able to call him before he passed, and tell him he was right. His response, 'Yes i know!'"
- DLightEn: "...Behold The Only Thing Greater Than Yourself..."
- dlbucs: "When I was about 18, my dad instructed me to 'get the hell out of here!', with 'here' being our home. I complied and joined the U.S. Navy. Thanks Dad, the advice was excellent and I'm glad I listened to you! By the way, my three older brothers got the same advice and all served in the military. Thanks again Dad (as I look skyward)!"
Fatherly advice from other sources
- Irwin M. Fletcher: "My dad split when I was young, but my grandfather used to say this little poem a lot. 'A wise old owl sat in an oak / The more he saw, the less he spoke. / The less he spoke, the more he heard / Why aren't we like that wise old bird.'"
- anotherowner: "Actually from my Mother. 'If you get that little girl in trouble, you will marry her!' I always respected 'that little girl'!"

- alboalt: "The best advice I got from my dad was 'Learn to type.' This was back in the 1970s when men usually didn't learn. My typing skills indeed helped me later in life. And from an ancestor: 'Debt is an alluring siren, but pay day is a monster.'"
- Corky Goldstein: "When I was about 11 years old, I studied really hard for a big history test in school, got a C, and I said to my Dad, 'Life is just not fair,' and he said, 'Get over it, and get ready for your test tomorrow…always look ahead.'"
- Jeffrey Rowland: "When I was in college and came home on break with my ear pierced....my father said "just what you needed another hole in your head". All I could do was laugh because his favorite saying was 'you need that like another hole in your head' whenever I would get something I didn't need."

- wingman1: "Don't play in the street."
- baseliner5: "1. Never stop learning. 2. Don't get a girl pregnant."
- oldladyfromKansas: "'Don't ride the clutch.' (my dad was very practical)"
- seanoneil: "righty tighty, lefty loosey"
- Jannine: "My father was a state cop — harsh and hard. He always told me 'Stay out of it. Don't get involved,' when encountering any situation with an individual who had a problem, since my tendency was to rush in and try to help with whatever was going on. He seldom took his own advice, however, and would help just about anyone with anything."

- zippy d dudah: "Wherever you may go, always leave it better than you found it."

Patricia Krentcil — New Jersey's infamous "Tan Mom" — has found herself in the tanning and recording booths, and now she will appear in yet another one to sign autographs at the Exxxotica Expo in Edison next month.
"Excited! Just got my Pictures for @Exxxotica to sign! Come see me if your (sic) in NJ 10/4!! One Day Only," the 44-year-old Nutley resident tweeted this morning.
Exxxotica — a three-day event dubbed a "dedication to love and sex" — features adult film stars, who fans have the opportunity to meet, as well as products and performances.
Among the porn stars on the guest list are Jenna Jameson, Kelly Devine and Misty Stone.
It will take place at Raritan Center in Edison, where it has been held since 2008 after it drew strong opposition from officials in Secaucus (when it was hosted at the Meadowlands Expo Center).
In a separate adult entertainment business venture, back in May, Krentcil was reportedly offered $1,000 for a few hours of (clothed) work from Lucas Entertainment, which produces gay porn called "Kings of New York."
The Exxxotica Expo is scheduled for Oct. 4-6.

What are those red equal-sign pictures that are popping up all over Facebook about? You can thank the Human Rights Campaign, a group that supports gay marriage, for the symbol.
If you haven't seen the equal signs yet, you likely will soon; people on Facebook are swapping out their profile pictures and using these red signs instead as the U.S. Supreme Court discusses gay marriage.
The HRC asked its followers just yesterday to show support in this way: "Make sure you wear red to show your support for marriage equality. And make your Facebook profile red too!"
The Facebook profile photo idea has quickly gone viral.

Deferred features
The NetHack source contains code for several currently unimplemented features. Some of them are marked deferred, so they may or may not make it into the next version. Many of the following features are included in SLASH'EM.
The beholder (e):[1] a type of floating eye (in fact many eyes on stalks coming out of an even bigger eye; derived from Dungeons & Dragons) with 5 gaze attacks: slowing, sleep, disintegration, stoning, and cancellation.
Depending on how the gaze attacks work (none of them are coded yet), the beholder could be an exceptionally nasty enemy.
The shimmering dragon (D):[2] This would leave shimmering dragon scales and let you create shimmering dragon scale mail, which would confer displacement. Monster displacement is not yet implemented, which may be why this dragon is not yet present. There would be corresponding baby shimmering dragons.
The vorpal jabberwock (J):[3] A tougher type of jabberwock (level 20 vs level 15), enabled in UnNetHack.
The vampire mage (V):[4] The next step up from a vampire lord, with spellcasting abilities.
Charon (@) and Cerberus are present in the source code[5][6] if
CHARON is defined, but even if it is, they are both unique monsters which are not placed by any current map. Charon is a very high level peaceful human who, if true to his name's mythology, will ferry the player across the also-yet-to-be-implemented river Acheron/Styx for a fee.
Cerberus is a very high level dog who is tangentially related to Charon in Greek mythology, as the guardian of the gates to Hades. In the SLethe patch, he appears on the final level of the Lethe Gorge.
The spellbook of flame sphere[7] and spellbook of freeze sphere[8]: creates a tame flaming/freezing sphere which will eventually explode at hostile monsters. These spells are fully implemented into SLASH'EM and are starting objects for flame mages and ice mages respectively.
Reading a cursed spellbook could curse random inventory items [9] if it were of level 8 or higher. No such spellbooks currently exist.
There are comments in the source hinting at copper coins and silver coins.[10][11][12]
A special artifact attack of magic missiles (analogous to Fire Brand's fire, Frost Brand's cold, and Mjollnir's lightning), has been implemented.[13] The weapon's description, most likely a placeholder, is "imaginary widget".
There is code for "burying" both you and monsters ("The floor opens up and swallows <monster>!"). You can be buried, and stay alive for a while (eventually suffocating), and you have the opportunity to tunnel out.[14]
Other features
A user has suggested improving this page or section as follows:
"Deafness and the energy vortex's drain energy attack are both implemented in 3.6.0. Should these be removed from this list?"
There is code that gives a 1 in 25 chance of applied bullwhips yanking a monster's weapon away from it, and it hitting you.[15]
There is code that lets monsters use scrolls of fire as a last-resort offense.[16]
There is code for creating force fields over an area of the map.[17]
There is a hint that randomising the order of the elemental planes is a possibility.[18] Some variants implement this, including UnNetHack and GruntHack.
There is code to give elves a luck penalty for wielding cold iron.[19]
There is a hero attribute
nv_range which suggest intrinsic night vision may be implemented one day.[20]
The code for snagging shop inventory from outside the shop (currently requires a grappling hook) has a comment mentioning the possibility of telekinesis.[21] This is partially coded in several functions to do with picking up items.[22] [23][24]
There is a comment when using a stethoscope to make sure you have ears and are not deaf.[25] The ears check is not implemented. However, deafness is actually implemented using using the
soundok flag[26], but you only go deaf when you fall unconscious (from sleep[27], hunger[28], or eating rotten food[29]), which means you wouldn't be able to use a stethoscope in this state anyway. (Surprisingly, there is another way to go deaf, which is by setting the sound option to false, but it is unclear why anyone would willingly do this.)
There is code regarding invisible objects.[30]
Drain energy attack is assigned to energy vortex but as there is no code to handle it in gulpmu and gulpum functions it have no effects.
According to definition in monst.c eating footrice and some other monsters should convey stoning resistance, but this is not implemented.[31]
There is code for enlightenment to report that you are "warned of undead", but there is no other reference to that property anywhere else in the game.[32]

Seems like MSNBC wants to stir up fear by linking GE-designed nuclear reactors in the U.S. to those GE-designed nuclear reactors that are leaking in Japan. GE is linked to the Obama regime and the push for 'green energy technology.'
From OpenChannel:
The General Electric-designed nuclear reactors involved in the Japanese emergency are very similar to 23 reactors in use in the United States, according to Nuclear Regulatory Commission records.
The NRC database of nuclear power plants shows that 23 of the 104 nuclear plants in the U.S. are GE boiling-water reactors with GE's Mark I systems for containing radioactivity, the same containment system used by the reactors in trouble at the Fukushima Daiichi plant. The U.S. reactors are in Alabama, Georgia, Illinois, Iowa, Massachusetts, Michigan, Minnesota, Nebraska, New Jersey, New York, North Carolina, Pennsylvania and Vermont.
In addition, 12 reactors in the U.S. have the later Mark II or Mark III containment system from GE. These 12 are in Illinois, Louisiana, Mississippi, New York, Ohio, Pennsylvania and Washington state. See the full list below.
(General Electric is a parent company of msnbc.com through GE's 49 percent stake in NBCUniversal. NBCUniversal and Microsoft are equal partners in msnbc.com.)
Msnbc.com sent questions Saturday to GE Energy, asking whether the Japanese reactors differed from those of the same general design used in the U.S.
A GE spokesman, Michael Tetuan, referred all questions to the Nuclear Energy Institute, an industry trade and lobbying group. Tetuan said GE nuclear staff members in Wilmington, N.C., are focused on assisting GE employees in Japan and standing by to help the Japanese authorities if asked to help. The NEI on Sunday confirmed that the figure of 23 is correct.
The six reactors at the Fukushima Daiichi power plant, which had the explosion on Saturday, are all GE-designed boiling-water reactors, according to the anti-nuclear advocacy group Nuclear Information and Resource Service. The group says that five have containment systems of GE's Mark I design, and the sixth is of the Mark II type. They were placed in operation between 1971 and 1979.
