Hi,
In Lua, coroutines extend very nicely into time-based parameter
modeling.  A coroutine is kind of like a lightweight thread that runs
a function in another process but doesn't actually spawn another
thread, that is just the model.  It can be a bit confusing at first
but is a very useful concept for all kinds of collaborative processes.
 In the example below, I haven't made nice wrapper functions for the
coroutine code, so it's all flat.  One could design a cleaner
interface by grouping together certain operations in higher-level
functions.

wes


function fade_in(start, done, incr)
	while(start < done) do
		coroutine.yield(start)	--pass value to resume
		start = start + incr
	end
end

local coros = {}
local num_lines = 100
for i=1, num_lines do
	--create a new function with fade params as upvalues
	coros[i] = coroutine.create(function() fade_in(math.random()*-5,
math.random()*5, math.random()*0.2+0.1) end)
end

function draw()
	gl.Enable("BLEND")
	gl.BlendFunc("SRC_ALPHA", "ONE")
	
	for i, c in pairs(coros) do
		local status, val = coroutine.resume(c)	--get the current value
		if(val) then
		
			gl.Color(1, 0, 0, 0.4)
			gl.Begin("LINES")
				gl.Vertex(val, 1, 0)
				gl.Vertex(val, -1, 0)
			gl.End()
		
		else
			table.remove(coros, i)
		end
	end
end

Hello
Sorry for the "Stupid Question" but i'm a bit new to Jitter.

what will be the simples way to draw 2d text (or shapes) on the screen.(in full screen mode)

the only thing is that i need to be able to position the text/shapes precisely on the screen using the screen coordinate. (x,y from the top right corner)

thanks
Saar

you need to attach the jit.wake to the jit.window, like you have with  
the pwindow

comparing apples and oranges, so the question doesn't really have an answer.  *usually* processing your videos on the gpu will be more efficient, but this doesn't seem to be what you're asking.

thanks wes, this is great.

uh yeah, finally someone points this out.   I was wondering.  Anyway,
what happened is I scripted a bunch of GL enums and apparently GL_ONE
occurs more than once  in the GL spec and extensions so it took the
last one which is not the same as is used in the blendfunc arguments
for example, thus the error.  I'll post a new version tommorrow to fix
this and add some new things.

Huh.  I didn't know that the jit.qt.movie objects had that built-in.

BUT - I swear that using a qmetro instead of a metro in the CPU  
patches makes them more stable.  Maybe I am smoking the crack today.

Subject: [jitter] Feasability Check for a project
Message-ID: <1df68.4753d461@www.cycling74.com>


Hi,
My last project worked out wonderfully, thanks to pmpd and this message board. I am now working on another project that needs to be completed before December 31st. I was wondering if you guys could point me in the right direction and give me some ideas on how feasible this idea is.

I need to make composite faces out of people detected in a video. Only one face would show up at a time in the video. I could use cv.jit.faces to find the face. I could then use alpha masks eyes, nose, mouth, cheeks, etc which would be scaled and applied within the cv.jit.faces box. I would need to scale, position, and compile the various alpha masks so that I have one alphamask which will fit over the face in the original video stream. I would then need to take a snap shot and scale it to my desired final image size so that it could be averaged into my original portrait. I want to use alpha masks for each facial feature so that people of various shapes of face will not cause strange blurs in the final composite image. 

Does this sound like the right way to do what I am trying to do? Is this possible in my time frame and how would I go about positioning,scaling,and layering the facial feature masks so that they can be applied to my source images?

Thanks for any help!

Hello all,
Has anyone tried a Firefly MV camera in GEM in OSX??? I am about to buy one,
but need to be sure it works on a mac.
My reasons for getting this one are getting high frame rates. If anyone
knows of another cheap,  uncompressed firewire, high fps camera (this gives
120fps at 320x240 and accepts ROI, for 299$), please let me know.

best,

Could be overly ambitious in the time you have.  But then again, others might disagree.  Might want to try limiting it to a single facial feature or part of the face, then see if it's doable.

I'm curious as to how you'd go about applying the alpha masks.

Message-ID: <55B00BD9-FD8A-406E-9D04-FF430498B3C7@thierryfournier.net>

Hello,

Do you know if there is a framerate limitation in jit.qt.grab due to  
QuickTime, and what could be the method to bypass it ?

We are working with an AVT Guppy camera with Jitter on OSX. The cam  
is made for 640 x 480 @60fps (tests with the XP driver) but  
jit.qt.grab (and probably QT) blocks it around 25~30fps. The message  
"framerate xx" does nothing.

Has anybody ever experienced this problem and/or this cam ?

Thanks in advance,

I have a patch that jumps around a movie as often as every frame. Running this as a patch causes some jumps to be skipped over, or just not played fully. Using jit.vcr to record the output does not aid this.

I've heard of people exporting cut lists to an xml document that final cut can read, then letting final cut make the cuts, giving you a greater frame accuracy. Has anyone here done this? How would I start?

I need to figure out a way to take the part of my input matrix which falls into the box created by cv.jit.faces and scale it to my final composite size. After that I can apply alpha masks to get the facial features I am looking for, but I am stuck at the first step of scaling the initial matrix.

have you tried using different blend modes on the videoplane, that might work... (disclaimer) altho' i'll be the first to admit i have not tried it myself!

Subject: [jitter] [bug] jit.change report mode backwards
Message-ID: <83D74C04-552A-4861-A6C5-1A2859096146@lowfrequency.org>

Hi,

As far as I can tell, jit.change's "report" mode is backwards.

Expected: a different matrix into jit.change should trigger a report  
1, the same matrix should trigger a "report 0" message.   (As per  
HTML reference)

Results:  The real results are the reverse  - "report 0" for a  
changed matrix, "report 1" for a different one.

Blend modes wouldn't work, I don't think, as they don't provide you with a place to leave trails...to leave trails over another object you'd need to store them somewhere...as you can't use the render buffer because of the video.

It'd probably best if you could use a shader on your sketch output. But i don't know how to go about that :).

based on your original post, it sounds like all you need to do is implement some sort of non-realtime rendering of your jitter patch.
unless i'm missing something.

search the forum, there's several examples.

rendernode comes to mind...

thank you mr. Dekron, your pre uyvy method has gotten me a 768x768 movie run
a lot nicer on an xp.

btw. is there a method to force other post enviroments (aftereffects, shake
etc.) to export to uyvy.
most of the post friends i asked looked at me funny.

Subject: [jitter] [bugreport] inserting audio track in jit.qt.movie
Message-ID: <1e0bf.4757ee63@www.cycling74.com>


Hi all,

Here is a clear and reproduceable bug that started happening about two months ago, possibly after a quicktime update.

Description:
Inserting a new audio track into jit.qt.movie will only add the first 500 ms if it is uncompressed (i.e. quicktime says 'Integer (Little Endian)'). This bug does not occur when the audio codec is 'Apple Lossless'.

Expected result:
The complete audiotrack should be added.

Steps to reproduce:
See patch below. Here is the patch in a zip, together with two sample movies that you could use to test:
http://www.smadsteck.nl/movieinsertsoundproblem.zip (1.9 MB)

It would be great if someone could confirm.

Best,
Mattijs


The patch:

Hi,

I'm sorry that I posted a message earlier that isn't clear. What I'm trying to do is to use jit.qt.movie to open a quicktime movie on my hard drive. I have windows XP on my PC. I was able to open that movie from Max before, but it stop working anymore. The only thing I did was install the WinVDIG to active a web camera. So now the camera grab works but not the quicktime movie.


So here is the error message:

?error: jit.qt.movie: error -50 opening movie file

Any ideas?

Thank you so much!

Please send a patch showing exactly what you're doing. Where is the file 
located on your hard drive? What is the name of your hard drive, or the 
complete c:/path/to/the/file?

Thanks -

Again - what's the name of hard drive, or your username/account, please. 
Do you have non-english characters anywhere from the top level of your 
HD down to your desktop, for instance? That could make a difference.

My computer is a PC with Chinese Version of Windows XP installed.
This error message: 
?error: jit.qt.movie: error -50 opening movie file
kept coming up every time I press read from the jit.qt.movie

Thank you so much for helping me. I've tried 3 PCs and got the same error message.

Problem fixed when I separated the  Movie file from the Max file on a different drive. Have no idea why. Now new problem comes, my audio input stopped working after few hours. Any ideas? I like Max/Jitter, but it seemed so unstable, imagining it would be very difficult to rely on the grogram for a installation show.

Thanks a lot!

What do you mean you separated the movie file FROM the Max file?  
*confused*

Sorry about the confusion. I put the movie file on a flash drive. And left the Max file on desktop and it works.

that helps.

new user (<2mths)

i have been working on a multiple video mix patch that takes input from cv.jit/lkflow.  I have the input for this patch working well... sending the integers -1,0,1 corresponding to movement in left and right direction.

the goal with this patch is to select random movies that correspond with movement direction: left=-1/right=+1.  when the patch is inactive for 5 seconds it should (xfade) to randomly selected movie from the center list (0)

In addition Ive been trying to optimize for this playback.  ive turned off "use onscreen" and attempted to use "qlim" on the "pwindows"

MacbookPro, OSX10.4
QTmovies are compressed: 640*480 jpg, 10fps

Any advice, suggestions, or references to specific tutorials would be much appreciated.

thank you, this is my first official post.

Message-ID: <1e193.4759f61e@www.cycling74.com>


I have been working on some vertex shaders with the intention of creating shaders that generate more vertices than they are fed. its a bit tricky and goes against the general principle of glsl which operates on each vector individually, but I have found a partial hack in using jit.gl.slab, using @adapt 0 with the destination dim scaled by the ratio of new vectors being created by the shader.  is there a more efficient way of doing this? or a method that would allow for a non-linear expansion of the dimensions?

Hi maxlist,

I am working on a large project which requires the use of multiple projectors outputting various video streams. This is for a performance which needs to be portable and easy to setup. I have a macbook pro which will be used for all the video processing. I have not been able to find information on using multiple video outs from one computer. Will this require multiple computers to achieve?

else - yes - multiple computers - 

I use 2 networked macbook pros to drive 2 projectors and my sound...

Ah, thanks Julien.

This happens in windows as well, max 463&jit163 - but I don't know  
exactly what quicktime version, probably the latest(I can check if  
needed).

In osx, this happens with&without experimental jitter framework.

There is in the jitter documentation only a chapter how to write and implement GLSL shaders in the jitter format .jxs


Where can i get documentation how to write and implement a Cg shader in the jitter format .jxs?

What is the best to learn and go for, GLSL or Cg?
Is there somebody how knows a free and good GLSL/Cg shader editor with debugging for MacOS x?

this is not good advice.

there are very few applications which use uncompressed video well, and  
jitter is one of them.

i mean, NOT one.  use photojpeg if you have to jump from frame to  
frame or play backwards.

if your source files are dv use those, and play them in gl with  
jit.qt.movie @adapt 1 @colormode uyvy running into jit.gl.videoplane  
[glcontextname] @colormode uyvy.

Josh - uncompressed is ALWAYS the way to go if you have the drives to  
handle it. Uncompressed video has no inter or intra frame encoding, so  
jumping to a frame is just as easy as mjpeg etc - but you DO need fast  
fast fast disks to handle it otherwise you will be seriously sluggish.

Uncompressed SD NTSC is 27MB/s, uncompressed HD is ~160MB/s

If you have a raid, go for it.

I am sometimes using a program that comes with xcode,
called glsleditorsample. if your files have extensions like .vert or 
.frag, this is the default program. or are you looking for something 
more sophisticated?

the video in question is an animation, original files are single jpgs.  i have animated them with quicktime pro and reduced the file size to 640*480.  It works very well until I run the aforementioned random movie editor with cv.jit.  My jit.grab input framerate drops to about 4fps once I employ the editor.  I have attended to the pwindow, turning off the "use onscreen" and attempted to use some of the techniques from an earlier post on "jitter optimization".  Still, my incoming video is no higher than 5fps until I close the attached "editor" patch.

thank you for the advice, I hope this clears up the problem a bit.

of course...

i am working on the solution you suggested, but am having trouble getting the three lists to output one at a time to a single window.  i have been using "if/else" to control the bangs and it worked well on the first edit patch, but not yet on the "optimize edit" patch.  see attached patch-

thanks for your advice re jit.gl, it does improve the fps.  (the optimization post a few days ago has been helpful as well, i think i just need a little assist to implement it correctly)

sorry for my weird explanation ...

what i'm trying to come up with is quite simple ...

i tryed the expression

>jit.expr @expr "snorm[0]*9" "snorm[1]*2.5" "sin(smorm[0]*TOPI)"<

and filled the position matrix

to get my videoplanes arranged with jit.gl.multiple like this

o o o o
o o o o
o o o o

but i'm searching for an arrangement like this

o o o o 
 o o o o 
o o o o

is there a way to do this with jit.expr, or do i need to use a jit.scissor >> jit.unpack >> jit.op >> etc hack

greetings kM

if you want to displace a row of objects in 3D like that, then you
could turn snorm[0]*0.9 to snorm[0]*0.9+cos(norm[1]*PI)

To get an answer for this you need to supply more info-
the answer to this may wildly vary according to your video playing and processing needs, and networking strategy (broadcasting jitter video, or only control data, etc.). You need to supply more details on what you are planning to output: straight quicktime, processed matrices, opengl (which you may not broadcast through the jitter networking objects but must either read back to matrixland or broadcast only the control data). Also relevant are the pixel dimensions of your output.

Concerning multiple stream solutions, you can sometimes also improvise, such as outputting one stream via the video out and another through firewire (which again limits you to matrix output).

With a triple head 2 go, you'll have to be careful about pixel fill
rates from your GPU.  Relatively expensive shaders like phong shading
can add up quickly on large display dimensions, especially if each
frame has lots of objects that are nearly screen size.  This can be
counteracted by rendering to texture smaller than screen size but you
will lose some quality although in most cases a good compromise can be
found.

When you are doing [jit.op @op -] , it applies to rgb _and_ alpha.   
you're essentially removing your alpha channel.

try using [jit.op @op pass - - -]

So i have to buy the book but it is too expensive for now.
I will check glsleditorsample.


It doesn't have to be sophisticated because i wanna try if it is possible for me to get into shaders but a little debugger and a few examples how to start helps a lot.

The book is good for learning shader design like how to build your own
per-pixel lighting shader or how to do reflection and refraction.  If
you want to know more about the Cg spec, download the documentation
from Nvidia's site.  You can probably find shaders online and teach
yourself without having to buy the book if it's too expensive.

Do you have non-english characters anywhere from the top level of your

That is the problem, I have chinese character in the path.

and using [jit.op  @pass - - -] will "pass" the alpha, and subtract  
the other layers
using [jit.op @op -] will subtract all the layers, including the alpha.

see here :

#P window setfont "Sans Serif" 9.;
#P window linecount 4;
#P comment 302 72 100 196617 this will pass the alpha \, but subtract  
the differece on the others;
#P window linecount 1;
#P newex 302 126 102 196617 jit.op @op pass - - -;
#P newex 136 126 63 196617 jit.op @op -;
#P window linecount 2;
#P comment 136 97 100 196617 this will subtract all layers;
#P window clipboard copycount 4;

AUVI objects have issues with Alpha channels - I dont think they  
properly premultiply alpha - Kurt knows about this, but dont expect  
any updates :(

Subject: [jitter] jit.qt.movie - low frame rate
Message-ID: <1e226.475d233e@www.cycling74.com>


Hello All.

I'm trying to play 3 H264-encoded movies simultaneously using three jit.qt.movie objects. Eventually, I'd like them to play on three separate monitors.

However, I'm getting very low frame rates (between 8 and 12) and eventually it drops to 5 fps. When I play the three movies at the same time in Quicktime Player, I get the full 25 fps.

How can I increase fps in Max? Is jitter inherently CPU intensive?

Jonathan.

H264 is an awful codec for real-time because it uses an inter-frame  
compression mechanism. You'll have much better performances using  
Photo-JPEG codec for example. Have a look to the archive for detailed  
informations.

search for "optimization" on the forum. vade's and tyler's threads are very
recommended.

jit.cellblock, bline, pak, suckah, ubumenu (... sorry my memory keep  
forgetting the others?) were objects which were introduced with  
jitter, and since Max 4.5 they have been included in the Max standard  
distribution. Note however that jit.cellblock won't be able to deal  
with jitter matrices, unless you have Jitter registered, otherwise it  
works fine (by maintaing is own data or  linking with a coll object).

Very nice patch. Ive been meaning to move to a poly-ized version of my  
movieplayer - maybe ill just use yours. Good stuff.

Ive got a pretty nice thumbnail video loader (similar to grid).Perhaps  
ill hack them together. Nice work! It loads pretty well for my fairly  
large-ish movies, no hiccups for mjpeg 850x480 @30fps

Well done.

This is really weird. To me it looks like cos and sin are giving 
unprecise output. maybe rounding errors?

Subject: [jitter] OpenGL to QT movie
Message-ID: <1e29c.475e4aed@www.cycling74.com>


forgive me if this is a recurring topic but i am trying to record my openGL performances into a QT movie with sound... I saw a preliminary answer in the FAQ (recording jit.gl.render by drwing to a jit.matrix and recording that) but it doesn't seem to be working in my patch...

Does anyone have a patch/abstraction that will do something like this? Or any more detailed advice on how to do it? I am new to openGL and having a hard time figuring this one out...

Thanks!

Subject: [jitter] READING BITMAP DATA
Message-ID: <1e2b5.475eac63@www.cycling74.com>


Hello everyone,

i would like to know how i can write a simple programme in jitter
in order to read the actual data that is written in a bitmap image file (or jpeg, tiff...)
so i guess it would appear as a set of numbers.

I dont want to see the actual image but what the computer writes inside the file.

I know it is a very simple question, but it has been i while that i am trying to find on internet or around me how to do this.

thanks by advance.

Thanks for all your help... IshowU is impressive... records hi res and doesn't seem to slow down my patch at all. Surprised it is so cumbersome and inefficient to do this in Jitter, but I'm sure they'll make it easier soon enough... If anyone has any more openGL capture recipes please share, I think I will drop the $20 to get this project done using iShowU for now...

Thanks!

We are currently working on a school project where we want to send some camerainput over a wireless network. We have a 54 Mbit WIFI setup and a 320x240 feed of up to 20 frames per second. We use two windows xp laptops where one of them is connected by firewire to the camera.

We've experienced the same problem as posted by 'wagne342',
resulting in 17 seconds of lag between signal input and output.
This was the case when usimg jit.net.send and the complementary jit.net.recv.

We tried jit.net.broadcast but it resulted in an unreliable video stream, locking up all the time. If it didn't lock up, it still had a 4 second delay. 

Regardless of the compression, tweaking of framerate metros, qmetros or other variables, it continues to run into major latency and an unstable signal.

If anyone could give a hint or solution how to reliably compress and/or send the signal, we would be more than grateful.

Cheers,

Using the external capture programs is fine, and for that matter jit.desktop, but isn't the question how to bypass all that? I too would like to record what's happening in the GL window into a jit.qt.record (sound optional in my case). Do I need two simultaneous jit.gl.render objects for the GL part, one to a display window and one to a matrix to record? Having matrixoutput 1 isn't the same as capturing the GL result it seems, plus then you don't see what's happening.

I'm sure the answer is evident somewhere in the docs and tutorials, probably blandly obvious, but I do remember having problems with this, and at least it's on topic  ;)

reactable....that pretty much blew my mind...

You see a lot of cool interactive media projects out there, but a lot wind up being a couple pricey gadgets and some slick trickery, without too much complexity (once you know what you're doing that is). The reactable is definitely sophisticated on a number of levels... definitely the most impressive hardware / software / interactive piece I've seen yet. Thanks for the link... Now I'll just go off and wonder whether I'll ever get to such a level  ;)  or be able to collaborate with others that are (and have lots of funding).

Seriously, though, some kind of virtual GL version would be great for this. But man, that would be a lotta work... wouldn't it? I guess it's always less work if you copy ideas though. 

I remember seeing something similar virtually, where objects would connect in networks and send their synth / control info to each other, all in GL. Can't recall where that was though, or the name... dang.

I too would like to record what's happening in the GL window into a jit.qt.record (sound optional in my case). Do I need two simultaneous jit.gl.render objects for the GL part, one to a display window and one to a matrix to record? Having matrixoutput 1 isn't the same as capturing the GL result it seems, plus then you don't see what's happening.

Yeah that's possible, have a look at the glreadpixels message of jit.gl.sketch

hi,
google earth uses a special format to save geo information data (kml 
files). I am trying to build a (simple) earth projector using jitter and 
opengl and read these files (and also some other file types...)
The conversion should be easy, but precision might become a problem.
this is a shape in kml file format (longitude, latitude, height)

the precision is 16 digits, so I guess double float. does anyonw know, 
if opengl can handle that? or any quick ideas for how to approach that?

If your sending over the internet there isn't much you can do to improve delay besides decreasing the amount of data being sent or using compression.  H.264 is best for decreasing the amount of bits being sent but the computers decoding and encoding the data will be under considerable load.  For LAN I've used jit.qt.broadcast on a wireless n network and have had quite good results < 10ms latency with 480x320 30ish fps using compression.  Keep in mind that wifi G is not 54 Mbps, at best maybe 20 Mbps.  Do some calculations to determine the bitrate of your video and make sure it's within the full bandwidth of your network.  Backlogging of data will inevitably lead to poor performance.

If you want to consider nonrealtime capture, render_node could be  
your friend.  http://2uptech.com .

getpixels, render to texture with texture readback to the matrix (you  
can go from a jit.texture to a jit.matrix), etc. Look in Jitter/ 
examples/render and there is an example showing 3 ways to do it.

the jit.texture readback method is not in there, search the list. Id  
be more verbose but I ought to be working not mailing :)
