<Dark_Shikari> but you said XP
<Hfuy> The recorder side is XP, the edit side is Apple.
<Dark_Shikari> ahhhh I see
<Hfuy> Sorry, confusion.
<Dark_Shikari> you're intentionally torturing yourself ;)

<Hfuy> Well, to be honest, building these little recorders around mini-ITX boards didn't give us much choice.

Here are some memorable quotes gathered from various MPlayer and FFmpeg related discussions. Beware of what you say, because it will be recorded, taken out of context and ridiculed!

IRC Channels


<ods15>    btw, gcc took 900mb of ram and then segfaulted for me when i tried to compile a 30mb C file :P
<ods15>    that took about 20 minutes until it evantually gave out of mem error
<ods15>    i should probably just write my own compiler than can do it in 0.05s and no ram...
<ShadowJK> can tcc compile it :)
<ods15>    ShadowJK, heh i should've tried that
* ods15 just makes a sample file and tries now
<ods15>    ahem, it did it in like 3 seconds and no ram :P
<poirierg> great new ppl! I'm likely to get laid before linuxtag!
<poirierg> woops
<ods15>    ...
<poirierg> great new ppl! I'm likely to get laid out before linuxtag!
<dalias>   lol poirierg
<poirierg> budget cuts and stuff like that....
<dalias>   poirierg, oh
<dalias>   i read that as 'get laid'
<dalias>   and i was like wtf tmi
<ods15>    ja
<dalias>   the word is 'laid off' btw, not 'laid out'
<delewis>  haha.
<ods15>    so, wait, great?
<poirierg> okay, I'm getting laid off
<ods15> british is american with a sloppy accent, and much stupider curse words
<poirierg> cartman, you don't see smart girls if you only watch pr0n
<superdump> Welcome to ye Olde #mplayerdev Tavern. If yaoi 'n' free cola is what ye be lookin' far, we's got 'em! Yarr...
<dalias>    because you can't use x264
<superdump> why not?
<dalias>    because the decoder is slower than gabu trying to get a girlfriend
<dalias> h264 is like matroska
<dalias> yes mmatroska is better than avi but it sucks still
<dalias> hes h264 compresses better than mpeg4 but it sucks still
<dalias> and the question is: is 15% compression gain worth 500% performance drop?
<poirierg> do you know the difference between God and dalias ? ;)
<dalias>   god only tells you what's bad to do when you inhale from a burning bush
<dalias>   dalias tells you what's bad all the time
<reynaldo> i was once atacked by one of those beast
<reynaldo> i was 4 years old iirc
<reynaldo> those birds have almost 4 meters measured from the extremes of their wings
<reynaldo> i have some stories you wouldnt believe :P
<reynaldo> i dont remember meeting any chilean atacked by a condor besides me
<reynaldo> :P
<reynaldo> i was once biten by a black widow too :P extremely hard to find spider
<reynaldo> nature has been trying to kill me since the day i born!
<reynaldo> :P
<iive>     i though condors doesn't attack humans.
<reynaldo> they dont
<reynaldo> thats the weirdest part
<reynaldo> :P
<iive>     well, then there is only one explanetion. you are not human.
* iive runs
<reynaldo> :P
<reynaldo> who knows
<reynaldo> maybe the karaoke filter is just the begining of my world domination plan
<reynaldo> why dont you work with me improving the filter then ?
<poirierg> reynaldo, because I don't want to steel the paternity of your little toy
<reynaldo> thats not my boy
<reynaldo> everyone an his girlfriend facing the same problem solved it the same wahy
<reynaldo> we can make something neater
<reynaldo> :)
<poirierg> your are calling me to become the girlfriend of you audio filter?
<ods15> i'm waiting for someone to send me brains tommorrow, not much to do until then
<snacky> h264-in-mpeg is standardized since 2003. if hd-dvd does it differently it's because they're stupid ;)
<iive> they do. thay are
<KotH> Rathann: some nice quotes you have there :)
<Rathann> I know! ^_^
<Rathann> I've been collecting them for months
<KotH> and some i dont even remember typing ^^'
<Rathann> ^_^v
<Rathann> hehe
<Rathann> it's good to have logs
<phcoder> compiling svn:
<phcoder> allcodecs.c: In function 'avcodec_register_all':
<phcoder> allcodecs.c:67: error: 'ENABLE_DCA_DECODER' undeclared (first use in this function)
<phcoder> allcodecs.c:67: error: (Each undeclared identifier is reported only once
<phcoder> allcodecs.c:67: error: for each function it appears in.)
<phcoder> allcodecs.c:253: error: 'ENABLE_DCA_PARSER' undeclared (first use in this function)
<phcoder> Sorry forgot to configure
<KotH> dont forget make distclean
<Rathann> don't forget to use your brain
<DonDiego> geez
<DonDiego> how many mistakes can you make in a single line of shell ..
<KotH> one per character
<DonDiego> i'm quite close ;)
<DonDiego> sundays after parties are not the best days for programming ;)
<cartman> <poirierg> cartman, you don't see smart girls if you only watch pr0n
<dalias> :)
<cartman> this is all I get for reporting quality pr0n bugs
<dalias> cartman, it's what you get for making statements about girls being stupid
<cartman> dalias: girls are stupid anyway
<ShadowJK> "I have to agree with Rich's supposed opinion here.  It is beyond mad."
<ShadowJK> dalias, you've become quite efficient at flamewars, when you don't even need 
to participate anymore, people just assume what you were going to say :)
<iive> btw does somebody know a way to get the xvid bitstream syntax number
<iive> the number that xvid put to identify what bugs they had when encoding it.
<Rathann> rtfs?
<iive> i ask if somebody knows
<iive> this is if nobody knows
<iive> fucker
<rxt> hehe, nothing changed on mplayer while I was away :)
<snacky> ugh... you guys should see how polite superdump is being to lusers on #ffmpeg . it's really disgusting
<superdump> :)
<snacky> what is it with polite people?! don't you realize you are making the rest of us look bad?
<KotH> i talked with an ubuntu guy here
<KotH> and the biggest problem they have is that upstream is uncooperative
<Rathann> is it?
<KotH> from their perspective yes
<Rathann> I haven't seen any patches from anyone @ubuntu
<Rathann> nor bugreports, for that matter
<KotH> well, replace upstream by downstream and you get the same in green
<KotH> the biggest outcome of a 2h+ discussion was that both sites want to work with each other, but think it's impossible
<Rathann> why do they think we're uncooperative?
<Rathann> (obviously we aren't)
<KotH> well... have a look at our history
<ShadowJK> Obviously uncooperative. Refusing to integrate with gstreamer, copying libraries 
randomly into source tree, breaking compilation with gcc2.96 on purpose, stuff doesn't compile with PIC, etc etc ;)
<KotH> yeah.. these points come into play too
<KotH> but that's a longer story
<ShadowJK> You know, I don't think those MPlayer developers even go to church of Xiph every 
week to worship a speedy emergence of Tarkin and ogm as the world dominating system
<KotH> anyone here who has an understanding of x11?
<ods15> it shows graphics :P
<KotH> yeah, right
<uau> i was already a better coder than most existing developers when i got involved with mplayer
<snacky> you guys and your secrets
<KotH> there are more secrets around mplayer than you could possibly imagine
<KotH> like, is there really a michael niedermayer? and if he exists, is he a single entity? is he alien?
<snacky> I wonder if he/they/it has/have any spies in here.
* KotH whistels
* Rathann checks if his tinfoil hat is in place
<xiphmont_> Vorbis still stands up nicely.  Theora, OTOH, is a a bit embarrassing.
* dalias tries to be polite about theora..
<xiphmont_> rather, it's a bit embarrassing until you look at the code, then it's alot embarrassing.
<xiphmont_> and that's 70% 'really fucking stupid encoder, really On2, be ashamed' and 40% 'format
design flaws'.  It's so bad it adds up to 110%.
<xiphmont_> I plan to help Theora limp along not too embarrassingly until it can be replaced for
real-- possibly 2-4 years.
<xiphmont_> Theora is actually fixable tho.  The amount of low-hanging fruit is staggering.
<xiphmont_> I mean, an entropy backend that results in *more* bits being written than went in?  It's
just... wow.
<|Bio|> but i need fix fo win
<iive> how much do you need it?
<|Bio|> very much.
<iive> as i said, it is not really mplayer problem, mingw is the support library, it should take the ucs2 convert it to utf8 then do the opposite.
<iive> and, very much is not enough.
<@beastd> hallo iive
<@iive> hi beastd
<@beastd> and what's up with you these times, ivan?
<@iive> nothing much, flaming diego mostly
<KotH> video player development is anime driven anyways...


* KotH wants a point and click solution... w/o the click
<Micksa> I'm reading about motion compensation
<Micksa> some of this is serious voodoo
<Micksa> I love it :)
<dtm> you're a free software pimp, Commn
<Jan_> mplayer has a number of command line options that is large enough to overflow a 32-bit variable.
<iive> Commn: yeh.. usa people usually have problem with foregin languages like british, australian or canadian. :)
<CarlFK> how many gig is an hour of raw DV ?
<DogBoy> like from a porno?
<CarlFK> right
<DogBoy> just how raw are we talking
<CarlFK> right from the cam corder's firewire
<dtm> Commn: i read all of your wiki page and you forgot the final entry for "and seek professional 
  help immediately for the mental illness that either
   1) made you want to follow all these steps for lazy, codependent fools on irc or
   2) that you WILL HAVE after faithfully trying to implement all these steps for a week"
<dtm> http://mfrost.typepad.com/photos/uncategorized/gaaallllgh.jpg    that big dog is the cumulative laziness of a lot
      of irc users   the medium sized cat is Commn     and the one watching, frozen in horror, is me
<dtm> now is that a normal response for a cat who has a self preservation instinct?  i think not.
<dtm> HE LIKES IT!
<Commn> dtm : haha how long did it take to find that picture?
<dtm> Commn: somebody gave it to me and i kept it in a firefox tab all week coz it's so awesome coz
<dtm> Commn: since you asked for feedback, i'll say that you're extraordinarily diligent and conscientious, and
      the minority of that content is directly relevant to mplayer, and the majority is relevant to a "how to ask
      questions the smart way" type of document if not being totally redundant thereof
<dtm> you are a gentleman and a scholar, and true patriot
<sacarasc> dtm is cute when he is adoring someone
<Commn> dtm : yes, its a modified 'how to ask questions' docu
<Commn> its lame tho
<Commn> i might delete it 
<Rathann> dtm is such a clear case of user-support-induced insanity that I wonder why I am still sane sometimes...
<pianoboy3333> how long does mplayer take to compile?
<dtm> how long til the Point of Know Return?
<pianoboy3333> ...
<dtm> i'm sorry, was that question not as dumb as yours?  oh well i tried!
<dtm> <3
<iive> dtm: you are starting to sound like me.
<dtm> Hmmmm.
* dtm commits honorable ninja suicide
<Erb> Does anyone know how to launch the GUI MPlayer in Linux via PHP (in Firefox)? I can run MPlayer scripts
      in the background fine. I only need to do this for local videos for an application I'm building.
* dtm throws his brain into a blender in an attempt to comprehend Erb's question but fails sadly
<dtm> tell me what i want to know, and nobody gets hurst.
<dtm> hurt.
<Rathann> o_O
<dtm> i'm feeling like the giant cactus wants to be plastered in ascii screenshots
<dtm> HELP ME DO THIS, Rathann
<DazBrum> what is the channel for developers
<--     DazBrum has quit ()
<dtm> lols
<dtm> i think i'll spare them from that
<netstat> how come mplayer eating memory
<netstat> it uses up to 90% cpu
<dtm> must be a good movie
<cappicard> o/~ Ich versteh euch nicht! o/~
<dtm> i'm sorry cappicard i dont speak satanic
<cappicard> LOL
<cappicard> it's just German
<dtm> yeah but not when they're singing it.
<cappicard> heh :)
<iive> cappicard: isn't it the same
<gioele> How come that I get a 35 minutes MP3 from a 5 minutes FLV video with -dumpaudio?
<Compn> aliens beaming audio into your mp3
<spuck00> ^^
<gioele> Compn: time to call SETI?
<Compn> yep
<Compn> if the aliens are peaceful, say hello
<Compn> if they are aggressive, look out!
* richard___ wonders why so many people join this channel for no apparent purpose
<rsk> they share the love of mplayer ;-(
<sacarasc> i have a purpose
<richard___> I wasn't implying that there's anything wrong with it :)
<rms> please tell me how to use dd_rescue
<rms> and what  special will it do, except regular copy?
<rms> RTFM?
<KotH> the manual says everything oyu need to know
<KotH> read the fucking manual
<rms> oh ok
<iive> -dumpvideo
<LinuxCart> umm, that's a good idea. i'll try that.
<LinuxCart> thank you iive
<KotH> LinuxCart: if in doubt, it's iive's fault ;)
<LinuxCart> how could this be explained?
<iive> it just another of dv misteries
<iive> it's KotH fault.
<LinuxMafia> how can i turn on language and sub
<LinuxMafia> KotH, using debian or freebsd?
<KotH> LinuxCart: doesnt matter, the FM is OS idenpedent
<LinuxCart>  KotH: is RTFM some dialect to say it's iive fault :P
<ChaosR> MPlayer 1.0rc1-4.1.2-DFSG-free <- my version
<ChaosR> is it out of date
<mjunx> of course
<mjunx> if it wasn't built like within an hour ago at any given time, it's usually out of date
<Fatsobob> trying to get mplayer to play win32 on ubuntu makes me want to shoot myself
<Fatsobob> mostly because ubuntu is all "totem this" and "totem that"
<Quintin> Is there any reason to use opengl vo device?
<sacarasc> nope
<Quintin> what's it there for?
<sacarasc> because you might want to use it...
<reimar> sacarasc: is there any reason why I should think what you just said makes sense? ;-)
<sacarasc> reason and what people want are not always the same
<Commn> iive : dont call mplayer users dumb
<Commn> not to their faces anyhow
<Agiofws> has anyone tried cinerella ?
<Agiofws> i think it great 
<Kunalagon> I tried , and I thin 80 % does not work
<MisT_> never get compiled here
<Kunalagon> it has more bugs than my shelter
<voltagex> ArneB: at one stage I was able to do the maths to crack CSS on paper :P
<ArneB> voltagex: Obviously your mind and paper are illegal.
<ArneB> Better hand them over to the MPAA.
<voltagex> I think you could sneeze and accidentally crack CSS
<voltagex> yep
<voltagex> no more pencils
<danny500> how do I convert a ogm file into an mpeg file using mencoder?
<danny500> anyone>
<danny500> hello?
<danny500> ?
<danny500> help
<BenrA> mencoder -of mpeg -oac lavc -ovc lavc -lavcopts vcodec=mpeg2video -o foo.mpg foo.ogm
<danny500> ?
<BenrA> If you want quality and/or DVD compatibility or anything, consult the docs. ;)
<danny500> ok that was confusing
<danny500> file equals = file:///home/danny500/Trigun/Trigun%20-%201%20-%20The%20%24%2460%20Billion%20Man 
<danny500> now, rewrite that code so that It'll work
<danny500> well then?
<BenrA> What is your problem?
<housetier> I'd try replacing "foo.ogm" with /home/danny500/Trigun/Trigun%20-%201%20-%20The%20%24%2460%20Billion%20Man 
(if that is the real file name), and see how far it goes
<danny500> fine then, don't help me, I'll go to a room where I'll actually get help. Fucking assholes
<crackedboy> hi, can I ask something about kmplayer?
<md`> no
<crackedboy> ok, sorry
<md`> you're forgiven
<CHodapp> I have a program that's basically just generating RGB data for a framebuffer. 
<CHodapp> I'm having major issues figuring out how to get this data to an encoded video.
<CHodapp> ffmpeg seems to only want some particular kind of YUV
<CHodapp> can I make mencoder handle raw RGB or raw YUV or anything like that?
<Commn> its easier to get it working with mplayer, to see what options you need
<Commn> mplayer file -demuxer rawvideo -vc rawbgr16
<Commn> etc
<Commn> then you can do mencoder with those opts
<Commn> or maybe even mplayer -vo yuv4mpeg , which ffmpeg probably accepts 
<Commn> maybe even use a named pipe... mkfifo stream.yuv && ffmpeg -i stream.yuv -options ...
<CHodapp> ugh, documentation is so sparse on stuff like this
<CHodapp> ugh, why is this such a pain in the ass, with everything
<CHodapp> hrm, maybe rawrgb24 is what I need
<Commn> what part is sparse?
<Commn> if you tell us, we can improve mplayer docs
<CHodapp> well, not so much in mplayer as everything else I've tried... I was mostly searching on 
the web to get some clue of how I'd convert what kind of raw input to encoded output
<Commn> mplayer -vc help|grep raw
<Commn> will show what raw codecs mplayer has
<CHodapp> Yeah, I just now found that
<CHodapp> blah . . . Cannot find codec matching selected -vo and .video format 0x30323449.
<Commn> CHodapp : try -vc +rawrgb32 or whatnot
<Commn> just add + in front of it 
<CHodapp> then it says the selected video_out device is incompatible with this codec
<CHodapp> tried sdl and x11
<Commn> if you can make a small sample of your file
<Commn> dd if=input of=output count=3 bs=1024k
<Commn> i can try to get it working in mplayer
<CHodapp> you might as well just take 640*480*3*100 bytes of data from /dev/urandom and try 
that... it will be functionally equivalent
<CHodapp> I'm using this right now:  mplayer -rawvideo w=640:h=480 -demuxer rawvideo -vc +rawrgb24 -vo sdl temp.rgb
<Commn> whats random got to do with it ?
<CHodapp> it's just a bunch of bytes, completely unorganized, and mplayer needs to know the resolution
<CHodapp> it doesn't care about the contents
<CHodapp> something else is wrong, otherwise I'd be getting something on the screen
<Commn> if you give me some file i can help
<Commn> otherwise its hard to debug from here ;p
<CHodapp> www.uc.edu/~hodappcm/temp2.rgb
<CHodapp> not the most coherent video, but you won't find that out unless you get something on the screen
<CHodapp> it's 320x240, 10 frames worth
<Commn> what program generates it ?
<CHodapp> just something I'm writing. it's all procedural.
<Commn> i'm trying to remember why it defaults to i420
<CHodapp> i420? like yuv?
<Commn> ya
<CHodapp> definitely shouldn't be yuv...
<Commn> i know, mplayer -rawvideo is defaulting to that
<CHodapp> hmm
<CHodapp> still no output?
<Commn> CHodapp : something like this didnt work ? ffmpeg -f rawvideo -pix_fmt rgb24
<CHodapp> couldn't find codec parameters...
<CHodapp> wait, I forgot the size
<Commn> haha more static
<CHodapp> what commandline did you use?
<Commn> ffplay -f rawvideo -pix_fmt rgb24 -s 320x240 temp2.rgb
<CHodapp> wonder if my endianness is wrong...
<Commn> is it black frames ?
<Commn> ffplay -f rawvideo -pix_fmt bgr32 -s 320x240 temp2.rgb
<Commn> CHodapp :
<Commn> CHodapp : there is an app on that page which generates rgb data
<CHodapp> yeah...
<CHodapp> by the way, I just sent you data from /dev/urandom
<Jan-> Just so you know, you do realise, the reason we're after using mplayer is because it's f@&^@ng brilliant.
<Jan-> It plays, as they say, *.
<Jan-> It'd play a bucket of cornflour if you painted the word "MOVIE" on it.
<nyersa> do I need to also specify the aspect ratio?
<Rathann> that's too vague a question
<Rathann> so my answer is: maybe
<judaz> i hear music, but not de voices
<judaz> the *
<Rathann> well, it's good that you don't hear voices
<Rathann> hearing voices is usually a sign of insanity
<sacarasc> i want mplayer 1.0 final so i can laugh and hell freezes over and people stop being idiots
<ma3x> what do you need mplayer for?
<ma3x> full of bugs
<ma3x> get windows media centre
<rsk> yea
<rsk> get a brain
<individ> using mplayer revision 26668 fixed my obscure problem, thanks for the tough love :]
<^^MAg^^> Arwen: I'm not blind, it's using ffh264
<Arwen> ^^MAg^^, and where do you read "x264" in that?
<ProN00b> Kovensky, i like it better without ass
<Kovensky> ProN00b: you're weird
<anon32> Kovensky, why? Because he likes his text without ZOMGPONIES?
<ProN00b> no, but there are no ponies anyways, just smaller text


<grepper> you don't have -pix_fmt ?
<aum> '-pix_fmt list' worked - it just isn't advertised on the manpage
* aum pays due respect, and acknowledges that the *real* manpages are those files ending in .c, .h, .cxx etc
<grepper> it sure IS in my manpage
<grepper> maybe debian makes it from ffmpeg -h
<jaredthane> Now I'll just shoot myself in the head for being so stupid!
<andoma> do you want help with that as well? :-)
<benoit-> zinfandel: read the code
<benoit-> and come back when you know what you're talking about
<zinfandel> thats the 15 minutes i dont have now, but ok you win
<kshishkov|work> well, strictness of laws here is compensated by inability to enforce them often
 <encompass> so what does FFMpeg actually stand for?
 <Kuukunen> fast forward moving picture experts group
<peleg> oh, awful!!!
<peleg> these terrible sounds ripped my ears...
<iive> aac have been committed to ffmpeg?
<bigbear2> ok r 15190 is fine too
<zap0> is that 'stable' version now?
<Rathann> zap0: define 'stable' ;)
<zap0> somewhere you keep horses
<Rathann> oh, the horses have run already
<zap0> wild horses...   damn you horses!
<Hfuy> TroyMcClure?
<TroyMcClure> yep
<Hfuy> the TroyMcClure we remember from such video-conversion instructional films as "MPEG-4 - Suitable for Porn?"
<Hfuy> In order to make FCP* display this stuff without insisting on a render, all the stars will have to be in alignment, if you see what I mean.

* Final Cut Pro
<Dark_Shikari> Most NLEs are utterly trashy pieces of software
<Dark_Shikari> with video support that makes most late-90s apps look good
<Hfuy> Couldn't agree more.
<Dark_Shikari> despite being supposedly "professional" video editors they don't actually support any "professional" formats
<Hfuy> However, they are utterly trashy pieces of software I am bound to support.
<Hfuy> Uh-oh. Looks like it needs to me MXF-wrapped.
<Dark_Shikari> does FCP take DirectShow input?
<Dark_Shikari> I know Premiere does.
<Hfuy> Final Cut is available only on the Mac.
<Hfuy> This makes my life... interesting.
<Hfuy> Premiere also knows how to import EDLs with timecode and so forth, which FCP doesn't; absolutely the only way to get anything into FCP is using Quicktime embeds.
<Dark_Shikari> you're intentionally torturing yourself ;)
<Hfuy> You are aware I assume of what an egregious train wreck of a format MXF is.
<Dark_Shikari> so there's no mxf muxer I'd assume
<Dark_Shikari> I don't pay attention to awful container formats :>
<Dark_Shikari> that's the great part of working on a pure encoder app, you can let the ffmpeg devs torture themselves over awfully designed container formats instead ;)
<Hfuy> MXF is extremely awful. One cannot help but raise an eyebrow when a container format touts itself as solving all interchange problems, overnight and for ever.
<Dark_Shikari> lol
<Hfuy> What it actually does is take the interchange problem, wrap it up in a pretty box with a ribbon on it marked "MXF", and pretend that helps.
<Dark_Shikari> I think there's some inverse relationship between marketing claims and actual substance
<Hfuy> If it's any consolation, I'm having enormous grief trying to create timecoded Quicktimes on a Windows PC.
<Hfuy> ...yes, AVCI is MXF-wrapped. Curses.
<Hfuy> Oh, good grief, it's split-file A/V.
<Dark_Shikari> oh god
<Dark_Shikari> its not even interleaved?!
<Hfuy> With external XML metadata.
<Hfuy> I believe MXF can be. But in the case of AVC-Intra, it's not.
<Dark_Shikari> :>
* Hfuy allows his head to fall forward onto the desk
<Hfuy> What in God's name is --wrong-- with these people?!
<Dark_Shikari> lol
<Hfuy> Allow me to quote from the AVC-Intra whitepaper.
<Dark_Shikari> ugh, whitepapers
<Hfuy> Basic concept of AVC-Intra 
<Hfuy> Guarantee interoperability  Adoption of International video coding standard and MXF fle format
<Hfuy> Words fail me.
<Hfuy> So, how much money do I have to give you to have you implement MXF wrapping to SMPTE 381M?

<caldo_de_cana> ok, I need a little CS help... my callback function for vfwcap
locks a mutex to add packets to a list. lavf's read_packet function also locks
the same mutex to read packets from the list. If there are no packets on the

set from inside the callback, right?

Ok. :)

1. There isn't a spec, since the language hasn't been standardized. All
we have are numerous competing drafts written by independent,
non-authoritative organizations.

2. A large amount of existing English code, such as Shakespeare, is
unparseable by modern English speakers.

3. If an element of the language has been frequently misused over a long
enough period of time, such misuse often becomes acceptable.

4. An English speaker can be considered reasonably feature-complete even
if such speaker only recognizes a small subset of the language.

5. Certain keywords tend to cause internal compiler errors. Such
keywords are known as "profanity", and existing English speakers weakly
attempt to prevent recently-written speakers from being aware of them.

6. English is a highly context dependent. Many keywords, when used in
their own particular context, take on an entirely illogical meaning.
These "idioms" cause compilation errors, especially when an old speaker
is attempting to communicate with a new one.

7. ....

I could go on, but that's enough fun for now. :)

Gentoo's latest mplayer ebuild is apparently an SVN snapshot from
08/10/2006 and doesn't seem to include a fairies USE flag for
compilation.  Was fairies support added after that date, or is the
ebuild missing a USE flag?

Sure.  My crystal ball tells me that fiendish aliens have been using
force fields to obstruct the flow of cosmic energies in Christian's
machine.  The fact that the aliens have decided to sabotage FFmpeg first
should give us all pause.  It is a rare compliment to receive but it

FFmpeg preys on weak, unmaintained or closed-source codecs. If your
library does not meet those requirements, ffmpeg won't consume it (and
will use a wrapper if it is good one).
