Configure audio bitrate; CBR won't sound *quite* as good but it'll be fine, and it's more reliable.

I have unencrypted dvds

Oh.

all the magnolia films are unencrypted, PBS stuff there's more of it than you think

[17:05]

Is it one program per DVD? (Program == feature film, or episode of a television show, etc.)

what does the video window mean?

well it depends.

"video window"?

usually a couple hours of a series for example.

oh, okay.

[17:07]

there's a drop down for audio (lame...)

[17:07]

if they made it easy on you, on the DVD there should be a directory, VIDEO_TS.

[17:07]

and there's a drop down on video (copy, dvd, mjpeg...)

For the video, choose Xvid.

It's a safe bet.

Xvid4, rather.

Hit Calculator, then pick your target size...

it'll give you a Video size in MB.

[17:09]

Hit Configure under Video.

[17:09]

Switch Encoding type to "Two pass", then enter the video size from the calculator into Target size.

All others should be left alone for now. Defaults are a great tradeoff between speed, quality, compression and compatibility.

Note that you can't do most of this until you have a VOB loaded up.

(Or another AVI, or whatever).

So, in summary:

1. Open your source file.

2. Pick audio codec and bitrate.

3. Calculate video size.

4. Pick video codec and set two-pass filesize.

5. Hit save and wait.

[17:13]

For 1, one thing to watch out for is if they put more than one program on a title. (On disc, the title has a filename of VTS_XX_N.vob, where XX is the title number and N is first, second, etc. chunk of the file.)

it says this looks like mpeg do you want to index

?

Yes.

it says could not open the file

Oh. You ripping straight off the CD?

Yeah, it tries to write the index in the same directory.

yes. how can I make sure it's not encrypted?

oic, hold on then.

The best way is to rip it with SmartRipper. That gives you a lot more control over the way the file is ripped, too.

[17:25]

For the 442, you'll probably want to add a resize filter; that means clicking on Filters, Add, MPlayer resize; changing Bilinear to Lanczos3; entering a height (320 works nicely); setting Source to either 16:9 or 4:3; then clicking Apply, OK. Order is important on that filter, or the numbers get funny.

[17:27]

Oh, just found this, might be easier: www.doom9.org

[17:32]

JoeBorn: actually looks to be a lot easier.

[17:44]

<Eagle__Fire>

hi everyone

[17:57]

Eagle__Fire: 'sup

<Eagle__Fire>

not lots

<Eagle__Fire>

i've yet to fix my stupid tivo converter

what's wrong with it?

<Eagle__Fire>

makes avi files that play in any windows computer, but the 442 hates them

What codecs you using?

<Eagle__Fire>

i honestly wish i could get a firmware for the 442 that put out more diagnostic info

<Eagle__Fire>

xvid, mp3

<Eagle__Fire>

just like the other files that i converted in Virtualdub

<Eagle__Fire>

and those other files worked

[18:01]

Do you mind emailing me a sample of a good and a bad AVI? (I run my own mail-server, so my max. attachment size is around 10GB, but <50MB is preferrable)

[18:01]

steven at ninjacomputer dot com

[18:02]

<Eagle__Fire>

yes sir

[18:02]

<Eagle__Fire>

i'm on a slow cell conection right now - seems like all i'll have for the rest of this week

[18:03]

<Eagle__Fire>

i'll see what i can do

[18:03]

maybe encode a 30s file or summat?

[18:04]

<Eagle__Fire>

tivo files don't come in 30 second files

[18:04]

<Eagle__Fire>

though i can probly have the code stop after that

[18:04]

<Eagle__Fire>

it still doesn't work when the file is reinterleaved in virtuasldub

[18:05]

What's your code written in?

[18:05]

<Eagle__Fire>

C

[18:05]

<Eagle__Fire>

C++ to be specific

[18:06]

<Eagle__Fire>

Visual C++ to be very much more so

[18:06]

* srobertson waits for a version number

[18:06]

is there a place I can grab it, or something, or is this a closed-source dealie-o?

<Eagle__Fire>

it'll be open

<Eagle__Fire>

but at the moment it's unreleased

<Eagle__Fire>

owing to the fact that i may wish to add watermarking code

<Eagle__Fire>

i'll post it to the group

[18:08]

sounds great, thx.

[18:20]

* srobertson is away: Dinner. Better than Hamlet, at least.

[18:27]

Bob can look at the files to when they are available.

[18:28]

<Eagle__Fire>

bob's here?

[18:28]

he's not online now, no.

[18:29]

<Eagle__Fire>

so one would conclude that messages to him here would not reach him?

correct conclusion

<Eagle__Fire>

interesting

srobertson, it's working now. thanks.

I've had a lot of trouble getting autogk to put out files that will play on the 442.

I've never been able to get xvid to work.

[18:33]

divx works but way out of sync

[18:35]

<Eagle__Fire>

sync istn't a video codec issue

[18:35]

<Eagle__Fire>

it's an interleaving issue

[18:36]

<Eagle__Fire>

the 442 outright rejects my files

[18:36]

<Eagle__Fire>

(i've gotten xvid to work)

[18:39]

I know, others have gotten xvid to work, but they are smart and I am dumb

[18:43]

does that inspire confidence with everyone?

howdy

hey

finally :-)

yeah, sorry, this is a really low-activity list

you kinda have to ask your question and wait a day to get a response

(we should really say that in the topic)

s/list/channel/

so what's up?

[20:49]

srobertson, how hard/available is the api to get a myth type of device ?

[20:49]

hard? shouldn't be.

[20:49]

available: depends on when.

it's still kind of under development.

it's still very under development.

ah

but the whole thing's on a public SVN repo.

svn.neurostechnology.com

(the actual repo's at svn://svn.neurostechnology.com/svn/ )

i was so happy to hear the ethernet port inclusion is it final

it wa nto clear if this was only for developpers

oops

it was not clear from the forum/wiki

There's still some debate as to whether it will be on the Recorder 3.

ouch

And yeah, the Wiki needs to be updated.

That's my next project (after I finish my school-work, bleck).

But Google Groups is your friend:

[20:53]

groups.google.com

[20:53]

so one can at least expect a decent 2d api ?

[20:54]

The graphics will be built on Nano-X, an open-source embedded X11-like environment.

[20:54]

nice

[20:54]

There will also be a "Neuros Widgets" library (I call it NeWT, but nobody else does) so you aren't stuck drawing widgets pixel-by-pixel.

[20:56]

Finally, after I clone myself, I'm going to get one of the clones to write a nice library in Lua, a fast and extensible interpreted language, to get a lovely high-level way to add functionality built off the main application through simple plugins.

[20:56]

So, things like pausing live TV may be impossible, because of speed limitations.

[20:57]

But things like timed recording, mythtv "frontends" and servers, network streaming, DataDirect, etc. should be a piece of cake to do.

[20:57]

i am goting to pray it gets ethernet now

[20:58]

Don't pray. Talk to Joe. He's in here right now, although he's probably not paying attention.

[20:59]

Well, you can pray, too. I guess that's allowed (for now, at least).

[21:00]

* srobertson thinks Yono still remembers randonimity

[21:01]

da-dum-chee! anybody? anybody?

[21:01]

* srobertson suddenly realises that he's not actually funny, and goes to hide in a corner

<unknown_lamer>

srobertson: fuck lua, just use guile

<unknown_lamer>

Guile is better ;-)

<unknown_lamer>

And runs on the ARM

<unknown_lamer>

Like if hte 442 runs Linux then Guile will work

Same with Lua.

[21:06]

code in c

[21:06]

dos000: Great for core apps. Not good for plugins.

[21:06]

then xul

[21:07]

xul/javascript

[21:07]

unknown_lamer: I'll definitely look into it. Lua is by far the best that I've considered so far, but I haven't even looked at Guile yet. Had experience with it?

[21:08]

dos000: The *entire O/S* should fit in 8M of flash, from kernel to UI to media libraries. And it has to run alongside a video decoder on a 300MHz ARM.

[21:08]

dos000: I'd absolutely love to, but it's just not practical.

[21:09]

Or maybe it is. How small can we get an XUL interpreter?

[21:09]

entire mozilla is around 6

[21:10]

thats with fat libc i think

[21:10]

i can get back to you with exact numbers

[21:11]

We'd need to strip out just the XUL interpreter, make it run on an ARM, make it blazingly fast, and make it tiny.

[21:11]

We'd also need to expose all the functionality of the core libraries to it.

[21:12]

<unknown_lamer>

srobertson: I write guile apps

[21:12]

<unknown_lamer>

srobertson: it is a good dialect of scheme, and uses very little memory/disk space

[21:18]

unknown_lamer: hmmmmmmmmmmmmmmmmm.

[21:18]

have you guys took a look at picogui.org ?

[21:19]

kind of slow lately

[21:20]

hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm.

[21:21]

<unknown_lamer>

There is a guile project that implements an XUL parser

[21:21]

<unknown_lamer>

with output to just curses for now

[21:21]

<unknown_lamer>

XUL + CSS

[21:29]

I'm pretty sure our friends in China have sold themselves on Nano-X for now.

[21:30]

However, I'll take a look, and see a) which language to embed, and b) which toolkit to use, and c) if any of this is actually worth it (i still think it is).

[21:31]

On an unrelated note:

[21:34]

Can the hardware support D/A and A/D... _simultaneously_? (For audio, not video)

[21:34]

If so, how many streams?

[21:35]

I'm a chorus nerd. One of my teachers just spent $400 on a device that was nothing more than a Neuros 1 with a preamp, in terms of features.

[21:36]

Another is paying me $200 to help her make a part CD.

[21:36]

Bundling a version with a preamp and decent microphone, and billing it as a cheap, interactive multitrack recorder --

[21:37]

combined with the possibility for a USB-OTG CD burner --

[21:38]

would put the Neuros 3 (not necessarily the 442v2, but maybe, depending on sound hardware) on par with $1000-$2000 devices, in a totally unique position.

<unknown_lamer>

The 442v2 with a usb host could do multitrack field recording

Great for burgeoning singer/songwriters or bands who want to make a quick demo, or choral/band people who need practice CDs, etc.

<unknown_lamer>

300Mhz ARM + 4200RPM hard drive is plenty to do two track at a time audio recording

<unknown_lamer>

I'm not sure how many tracks it could handle for playback (disk speed issue), but I used to do 6 track recording with my old 5400RPM drive without issues

[21:40]

unknown_lamer: I actually meant multi-track as in, record one track, use punch-recording to clean up some, then play it back while laying another track down

[21:41]

<unknown_lamer>

yeah

[21:41]

<unknown_lamer>

the 300Mhz ARM can handle that

[21:42]

<unknown_lamer>

my 166Mhz P1 had no issues with six tracks at a time

[21:42]

<unknown_lamer>

And that was with 3-4 fx plugins running. Audio is not very cpu intensive

[21:42]

<unknown_lamer>

as long as the drive does DMA then there would be no issues

[21:44]

i am more interested in hooking the neuros 3 to the tv

[21:45]

think mythtv, mame type scenarios

[21:45]

dos000: The N3 is actually not designed for videos.

[21:46]

oops .. i meant the 442 b=nextgen i guess

[21:46]

Yeah.

The R3 is designed for real, consistent set-top usage, but no HDD.

the 442 is probably too portable and expensive, being enscreened like it is.

srobertson, i can live with no hdd .. i nfact i want it whithout

Perfect.

[21:48]

srobertson, what should i start looking at for code in the svn ?

[21:52]

is there going to be a remote as well ?

[21:54]

first question: I don't really know -- i've not really done much. I'm a full-time student, and I mean that completely literally.

second question: I know there's going to be a blaster, but I don't know about IR input. I'd recommend searching the ML.

<unknown_lamer>

I hated those days

<unknown_lamer>

Now I code for 15 hours a week and am only taking three courses

<unknown_lamer>

Soooo much free time

unknown_lamer: I really, really can't wait for college.

<unknown_lamer>

hahaha high school

<unknown_lamer>

god high school sucked

hahaha fuck you

<unknown_lamer>

But required no effort

(I say that in the kindest possible way, of course).

I'd say the hardest part about high school is focusing.

[21:57]

<unknown_lamer>

Focusing is blech

[21:57]

<unknown_lamer>

That is why I can only take three classes

[21:57]

<unknown_lamer>

I was lucky to develop an interesting in an area that lets me work as little as I do

<unknown_lamer>

Now that I don't have to fight my inability to focus and can work whenever I want I can sleep again

unknown_lamer, i am trying to do the same for the last 10 years

<unknown_lamer>

And my life is HAPPY

<unknown_lamer>

I even shaved my 5" angry metal beard off

<unknown_lamer>

unknownlamer.org

<unknown_lamer>

the before pictures are on someone else's camera

[21:59]

I am happy for you.

[21:59]

<unknown_lamer>

unknownlamer.org but that was january

[21:59]

<unknown_lamer>

imagine that + 2"

[22:00]

That was for the dress-up party, no?

[22:00]

<unknown_lamer>

yeah

* srobertson has always had a hard time taking an interest at anything non-numerical, so he's making a dedicated effort to try this thing called "socializing"

<unknown_lamer>

heh

<unknown_lamer>

Start smoking weed

<unknown_lamer>

You will meet the coolest people ever

[22:03]

ah, but: get caught smoking weed, betray the trust of my parents (we have a pretty nice relationship) and possibly lose considerable scholarships.

[22:03]

thanks guys ... must ... focus on .. this ..bug

[22:04]

oooooo-kay?

[22:04]

<unknown_lamer>

so?

[22:05]

so so?

[22:05]

wait, what was 'so' directed towards?

[22:05]

<unknown_lamer>

weed smoking

okay.

in which case:

so!

<unknown_lamer>

heh

[22:06]

it's a choice, and it's one I'll have to make.

[22:06]

But it's one I'm putting off until college.

[22:07]

<unknown_lamer>

college is where I gave up jesus

[22:07]

"He hasn't given up on you, son."

[22:09]

Yeah, I definitely have a lot to puzzle out about religion, too.

[22:09]

but -- GRAA -- must focus!

<unknown_lamer>

religion is for tools

<unknown_lamer>

honestly

<unknown_lamer>

It is entirely illogical

<unknown_lamer>

You can't just allow one part of your life to not be governed by logic

<unknown_lamer>

It allows for all sorts of little bad things
