The flowchart shows adding a signal ramping to zero from the last value of the 'old' sample.

Also you have to make sure Pd quits before any automatic shutdown because it does not quit when the system asks it to during normal shutdowns.

Re: [PD] Growing patch-window size (Was:Re: changing the look of Pd to be more readable)
Hans using your speedtest on my machine for the versions shows little difference in the times measured (old Powerbook G4 667MHz OSX10.4.8). time to display the patch is much longer than the measured times - a couple of seconds at least in the newer autobuild - and CPU reads high for most of that time. I added an [osc~] to test the effect on audio - there are of course dropouts during opening and closing on each build, but the redrawing the window in the newer build gets much worse with audio on, for example resizing the window can take several seconds. The audio does not drop out during this redraw. A very interesting difference between the two builds is: - in the older build with audio on I can see the drawing process (no dropouts) - when the window gets smaller there is no visible redraw and no delay, if the window gets larger the new area is imediatly drawn in white but remans white for a while before being filled in, there seems no change to the area already drawn - in the new build the whole window is redrawn with any change in window render area, with much longer waiting times when the window shows many objects even if none of them change or only a small change is made. When the window is made smaller the whole visible area appears to be redrawn. There are still no audio dropouts but now the window border takes some seconds to update (unlike the older build where the border is drawn quickly but the details a drawn later). I hope this may give some clues as to where the problem is. simon Pd-0.40.3-extended-20071104 61.935 27.534 27,507 closed pd then reopened: 28.551 27.44 Pd-0.40.3-extended-20071109 53.346 28.093 28.555 28.333 On 13 Nov 2007, at 2:59 AM, Hans-Christoph Steiner wrote: On Nov 11, 2007, at 11:12 PM, simon wise wrote: On 12 Nov 2007, at 10:02 AM, Hans-Christoph Steiner wrote: simon wise wrote: Playing around and testing it seems something (possibly in the new visuals) is slowwwing down displaying/opening patches i've noticed the same. cheers, robbert -- pd-0.40.3-extended-20071106 mac osx 10.4.8, 15 G4 PB 1.67 GHz, 1 GB ram The changes that I made to enable the different colors are really quite trivial so I have a hard time believing that to be the culprit.

As I understand it, if you are using DV codec with firewire you are going to get several frames delay (on any OS) - I guess this system is optimised for capturing media for editing, favouring accuracy rather than latency, not so good for real-time use. I have tried many different combinations of DV camera and capture system, always there are several frames delay with DV. Composite capture cards can be much faster, and can be better resolution too - but they get very expensive for higher resolutions. Without locking the camera's framerate and the capture card together you are always going to get a frame or more delay. Very high end digital mixing systems have a exactly one frame delay, allowing for processing the signal etc and all the cameras are locked in sync. I settled on a PCI framegrabber from Eurosys, not cheap but quite nice, and get a delay of less than 2 frames - just fast enough to get away with putting the image of a performer speaking up onstage without the sync between live voice and image being too bad. simon ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

The structures that that underlie a good piece of work don't need to be understood on a direct analytical level by an audience member, formal structures - mathematical or otherwise - can often help create a work that is more whole and reads better regardless of whether that structure is read directly (if an individual audience member also understands the structure this can add another kind of interest to the work for them). On the other hand it is very important for the artist using formal structures in their work to understand what they are doing. It certainly isn't the only way to make art, but if you are going to go that way then understanding the structures you could use is crucial. And work that is more purely formal, intended only for an audience with a knowledge of and interest in the structures being used, isn't only for the 'bitter and elitist' artist - it is also part of the way artists can share and build techniques, a way to 'talk about' structure and form in a more practical way, perhaps in parallel with formal analysis, perhaps not. This feeds into work for a broader audience and helps the artist and others understand what is going on in their practice. simon ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] synchronised video outputs

A friend who works in a art exhibition space told me there would be couple of solutions for this but both involve buying pretty expensive equipment like special DVD players. I thought then that a solution for this issue could be to have several computers on a local network playing video (with GEM) and synchronise them via OSC. But I dont have any experience doing such a thing, never used OSC for anything similar. Also I dont have a clue about how to synchronise together videos. Has anyone done anything similar? any experiences to share? yes. we used a dual-head machine (actually it was a quad-head, so we had plenty of space for editing...) running a single gemwin covering both screens and 2 [pix_film]s that were controlled by the same counter. since Gem allows you frame-accurate access, the 2 videos were in perfect synch. but we might need up to 6 to 8 video outputs, thats too much for the same machine. Thats why I thought about having a machine per video output connected to a LAN and synchronised via OSC. I've done it often, the basic principle for keeping the LAN machines in constant frame sync, allowing scrubbing etc, is each projector has a slave patch that uses [pix_film] to play by frame number rather auto, and receives those frame numbers (via [netreceive]) from a master patch which has a metro counting the frames and which plays any sound required. Works very cleanly and doesn't put much data through the network. Two [pix_film] Gem-chains in each slave will give you X-fades etc. I could post the set of patches which add quite a bit more functionality than that if you like, I've built up a collection over several projects. simon ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

I've used it with 5-projector wide images with fast movement across them. The biggest challenge is always getting the codec right for the circumstances, issues like whether the original was interlaced can be tricky. I find the results always better than DVDs which where often the more expensive alternative.

Is my expectation simply wrong?

It took me a little while to work this out, so I'll share this in case anyone is looking at similar problems, and wants to control exactly what inputs are used by X and when, so they can use keyboards, mice, tablets etc as controls in pd without also controlling the pointer etc ... A month or two ago Debian Sid moved to the new version of Xorg [some of the other distributions moved over earlier] and this has meant huge changes to the way input devices are dealt with, and now HAL is the primary way that X gets info about accessing devices. It is now possible to have a nearly empty xorg.conf, or even no xorg.conf at all.

This article is well worth reading to find out more: http://wiki.debian.org/XStrikeForce/InputHotplugGuide It seems that the HAL way of doing things, using it's configuration files, is a lot more flexible and much more hot-pluggable than the old way, but uses a completely different set of configuration files. I have been wondering how hard it would be to make [hidio] into something that works through HAL, maybe called [halio], to be able to access many devices that register with HAL instead of just USB devices, but to stick with a very similar interface to [hidio], and preferably stay compatible for usb-hid devices?? It would of course be Linux only because HAL is a purely Linux way of doing things. That would be a very long-term learning exercise for me, with no results for some time, if at all - but the results would be great!

Is the playback on each computer unsatisfying by itself (in which case I cannot be of help, whatever unsatisfying means), or is the syncronization between computers that is not perfect? In this second case, how much do you lose syncronization, i.e., how many frames of difference between any two computers do you accumulate per minute? If you just send a start signal to all computer and have them play the videos, and expect them to keep synchronized just by the exactness of their clock, I think it is impossible (with whatever software or codec) to maintain an acceptable synchro (meaning no much more than a couple of frames of difference) for more than a few minutes. I once had to do a synced playback of 3 videos and, if left to drift, they could stay apparently synchronized for as long as about 5 minutes. Indeed I was surprised by GEM's clock stability, I didn't expect so much (well actually i did, but I had been surprised a few months earlier with a similar application). To guarantee synchro within a given tolerance forever, I did a patch with one master and several (in my case 3) slaves where the master broadcast (via udp) its current time every N seconds (e.g. N=5) and each slave compared the received time with its own, and if the difference was greater than a threshold (e.g. 2 frames), it forced itself to skip or pause the needed amount of frames. It worked quite well. With a slightly more sofisticated patch you could correct the drift in a more gentle way than abruptly pausing or skipping a few frames. I used Windows (not sure whether xp or vista, I think xp) and DV-PAL codec. By the way, I never used pix_movie's auto mode: I turned it off and fed the right inlet with a counter incremented by bangs taken from the [gemhead]. But i dubt this makes any difference. I have synced several computers on a LAN successfully using a master, with a counter run by a [metro], sending frame numbers to the slaves via [netsend] and [netreceive], sending the frame number to each [pix_film] object. This way the master can also play audio which remains in sync, and pausing, scrubbing etc are all possible.

It should be fine, hopefully, by sending a master clock ascending value through udp.

Mine are fairly tired : it's both ibooks, with a 933Mhz processor. I first tried to launch my videos using VLC with the system object, which was much lighter for the computers. But the sync is not reliable at all, and the windows blink when opening : not clean enough for my installations ... I was thinking of trying VLC but never did, since the GEM way was much more flexible and I could create a nice interface in Pd. I've used some very low end machines (both old macs running OSX and debian on old PCs) as slaves quite successfully. Your ibooks will probably handle DV playback adequately, especially if they are the slaves and are not doing anything else. Quicktime has handled DV very well since much effort was put in to get Final Cut Pro working smoothly on the early G4s. Try using the raw DV format rather than the .mov format, or try without audio.

Is it more reliable/light than using a metro on each computer (which would allow me to change the playback speed) ??? well changing the playback speed with the [metro] might be unsatisfactory, because you will have all sorts of weird re-sampling artefacts. gemhead: +++++++++++ metro : 0 1 2 3 4 5 6 7 8 9 0 1 2 frame : 01235678012 as you can see, every fourth frame is dropped, which might look not so good. The method I have used reliably and with smooth playback is a single [metro] on the master machine, which sends the actual frame numbers to all the other machines. I think the Gemwindows had quite high framerates, linked to the refresh rates of the projectors. All the [pix_film] objects have auto off, and are sent the frame number explicitly so there is no playback speed at all - each frame is called for independently. This allowed much more flexibility with seeking and playback speeds, and has worked with 5 old G4 mac-minis showing a very wide screen movie where it was vital that they showed exactly the same frame (there was some very fast dance movement running across several screens and the movies looped indefinitely). Use the master to play any audio so that the metro stays in sync with the soundtrack.

(without side-effects to the linked friends?) I often use linked sliders, to duplicate controls in different places, but rarely connect the inlets/outlets and only use the send/receive symbols and the mouse. It can save quite a bit of messing around controlling the sync manually, especially when an external control surface like the BFC2000 is used. I assumed that the reason the graphical representation of these inlets and outlets disappear when the send and receive symbols are the same is that they become almost useless. When this special behaviour isn't what I want I use two different symbols. Occasionally I have used the outlets, for special cases where slightly different behaviour is required depending on which slider was moved, and I guess the inlet is the way it is because it behaves internally the same as the receive symbol ... anyway it can be useful for some kinds of visual feedback, if used carefully. But ... controlling a single GUI using its inlet is deceptive - the position on the slider changes but this value is not output in any way, does not alter the linked sliders and does not reflect the last value of the s/r symbol ... the position of the GUI may or may not have been sent to the [r] depending on whether it was moved by the mouse or by the inlet. If I then bang the input, or move the slider a little, or click on the GUI, so that this new value is sent then all the GUIs are moved to this position, the [r] gets the new value and the local outlet gets the value but the other outlets don't - matching the behaviour when I move a single GUI.

Then you can get a bit fancy and use some other controller, I've used Spaceballs and tablets a few times. Finally if touring a show anything visual that is run using DMX from the lighting desk will be happily operated by the lighting operator, while if you add another interface suddenly you find in many venues you need an extra person to do those cues, so it can be worth it to buy (or make) a USB interface that takes the lighting protocol - DMX - and control your patch using a few lighting channels as part of the lighting plot.

Re: [PD] advice- multiple camera inputs
On 08/08/10 20:12, Dima Strakovsky wrote: Hi all, Coming out of the lurker mode to ask a question here :) I am kicking around an idea for a work that would require four camera inputs. The video streams would be remixed in realtime and output via a single projector. Was wondering if anyone has played with the scenario and has some advice to offer? My solution for this was using a PCI framegrabber card with 4 video chips, allowing for 16 video inputs into 4 buses, each 640x480. This was what prompted me to switch to Linux as there were no such cards with OSX drivers available. Using GEM I was able to use the 4 video chips simultaneously, and could use alpha blending with at least 12 layers of video if I also played back video files. More than 4 cameras simultaneously was also possible if I only wanted quite low framerates, but mainly the extra inputs allowed switching between several cameras and video inputs from within GEM. This was six years ago and there are more choices available now. Note that generally if using composite video very little, if anything, is gained by using a resolution better than 320x240, since that is about as much information as is available in most composite systems and GEM, or rather the graphics card, scales up very smoothly if set correctly, so you can mix with higher resolution video files very well. My prototype was on OSX with a single firewire video input, using DV, but I abandoned this approach because firewire [at least when using DV] has a substantial latency built in [about 8 frames]. It is not optimised for live use but rather for reliably transferring video from tapes. With the framegrabber the cameras were not synced so latency varied between about 0.5 and 1.5 frames [in a serious digital video mixer the cameras are synced together and the latency is fixed at 1 frame]. Using multiple input machines could work with some kind of streaming, but there would be latency and compression issues to consider, while if you get an appropriate framegrabber then the frames can be passed on to GEM quite efficiently so not much CPU is used, and all the moving around of pix data is over fast internal buses and the alpha blending is done in the graphics card GPU. I added a second graphics card later, so eventually I had 4 DVI outputs and 4x4 video inputs, this worked smoothly and it would have been very hard move all that data between different machines if I had used streaming instead. The framegrabbers were from Euresys, the graphics cards were Nvidia, but the choices would probably be quite different now, six years later!

I understand it is quite different to what is available in Max, but I don't use Max so I'm not sure. 4/ Using Linux allows for a different approach to working with hardware, if you are interested in using hardware to give a tactile interface to your music making then some approaches are more flexible using Linux, again Max does not run on Linux. Max is prettier and with more GUI, but is really more easy to learn? Perhaps it is a bit easier to 'discover' things by just clicking around the menus etc, but this is really only a small initial advantage, and good advertising. In any case real usage will require a similar learning curve after those initial stages, because most of what needs to be learnt is how to use a Graphical Dataflow Language to make music. Im not interested in video, only music and sound. What about resources (patches, objets, etc)? Pd has lots available, probably Max does too, maybe the fact that Pd is open source means that you, or someone else, can adapt internals a bit to your needs, or make externals that are more integrated with the internals, but that depends on your programming skills and interests, i.e. do you want to do some of your work in C? Maybe Max has a bigger user base, but maybe the FLOSS nature of Pd makes the sharing more open? I don't Know much about the Max community, so a comparison is not possible for me.

This was a few years ago, I guess the current versions would be PCIe instead it was a Euresys Picolo Tetra .. 4 chips on the card, each of which switch between 4 inputs .. there are 4 BNC connectors on the card, plus extension panels with 4 BNC each for up to 16 BNC total, or make your own panel if you prefer. A nice features is that each connection has a separate termination switch, so it is fine to connect some of them in parallel, and since switching between the source is accessible from inside GEM you can get a very flexible mixer going. It wasn't cheap, but I was very happy with it (and the overall system was hugely cheaper than any digital vision mixer capable of doing what I wanted). The company does industrial control systems using linux, so all the drivers were fine .. but actually the standard v4l ones worked well as I didn't need the extra features accessible via their drivers. I could do 4 simultaneous 640x480 feeds, and the CPU usage sending them directly to the screen was quite reasonable, allowing several other 1024x768 streams to be played from the disks. GEM (or rather openGL and the graphics card) scales the image very nicely. With the good cameras the image was very nice, though with any composite video there is not much information at better than 320x240 and it was hard to see any difference going to 640x480, the quality going via DV was better simply because DV is a cleaner, higher resolution, transfer than composite. The quality depended on the camera, not the capture. Various high definition capture systems exist, often very expensive. Latency was the reason I switched to this system, the performance was set in a kind of low budget live TV studio, so with a camera on a person speaking the DV delay was unacceptable, the lip-sync was way too far off between the live actors voice and the image.

Another note re video quality ... The choice of graphics card, and the speed of the motherboard (i.e. how fast you can move data between drives, PCI bus, CPU and graphics cards) are important choices for video quality. The motherboard choice is tricky as some of the faster boards for this kind of work are aimed at gamers, and maybe not so well supported in Linux. An Nvidia card with propriety driver is probably still the only way to go to give you reasonable control over the various scaling and syncing options to get the highest quality .. smooth scaling and no tearing etc. The Intel graphics option may also be worth checking out, their drivers are properly open and much easier to keep up to date ... and they have been getting much better in the last year or so. I haven't explored this yet. Forget ATI for this kind of work in Linux now .. maybe a year or more down the track this could change, maybe not.

Unless you go for rather expensive very high frame-rate capture devices, which are certainly available, the camera will only be capturing each pixel every 40ms, and even if you processed that information line by line it would be difficult to get any reasonable analysis before a whole frame was present.
