Quicktime movie .mov Size 1920 X 1080 I reduced its format size to HD 1280 X 720 and now [pix_film] is able to open it but reproduction is slow and choppy. I use [pix_film] to load Quicktime (.mov) DV 780 X 420 videos and they run perfectly.The same setup won't work with 1920 X 1080. I work on OS X 10.9.1 and Pd-Ext 0.43.4 extended. How can I load videos in full HD 1920 x 1080 in order to texture effectively? M Hello, to my experience, at least on linux, it is hard to keep good framerate with the current implementation of pix_film and HD files, regardless of the format, and it plays far better using pdgst library. https://github.com/umlaeute/pdgst although it still need some polishing (for controlling the playback of a file f.ex. ) the displaying of even multiple movies in full HD mpg4 or mjpg is fluid with it ... (I did a small fork of it on github - https://github.com/Olm-e/pdgst - to play with the code and added the seek parameter so you can control the playhead and speed ... but it still needs some stuff like being able to get the length of a movie to know when to stop, loop, etc ... Iohannes, maybe you can look at this a bit ?) hope it helps, Ol. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] HD 1920 X 1080
I want to play from start to finish. I have in my Final Cut Pro the choice of producing a file with the following codecs Quicktime movie Format Size 1980 X 1080 MPEG4 Format Size 1980 X 1080 H.264 for apple devices Format size 1280 X 720 (.m4v) What codec works best with format size 1920 X1080? One of these or is there another one more suitable. [pix_film] was able to open the .m4v (H.264 for apple devices Format size 1280 X 720) but when the video plays it stutters. What causes this? The codec or [pix_film] or my cpu's capacity? I'm running a mac pro with 2 x 2,8 GHz Quad-Core Intel Xeon and 6GB of RAM.

You have an Arp emulation patch? Can I get a copy? I have a MiniMoog emulation in pd, but I've been sitting on it for years ... just haven't been abel to add the finishing touches. I recently brought in the bandlimited oscillators in rjlib and it sounds really good now. It's not a perfect emualtion, but more in the same spirit with the same controls. I have the code for an ARP Odyssey that still works and it even has midi working. So it might be a nice starter project, especially if i can export it to a ipad/iphone.

Re: [PD] using pd live (sans computer/laptop/raspberry pi)
Without a computer, no. Without a desktop or laptop computer, yes. An embedded computer (rpi or UDOO, for instance) can totally do this and that's what some of us have used them for. Simplest case is to setup the system, install pd with your patch, and write a script that is launched when the machine boots that connects to the sound card and starts pd. This way it starts immediately when you turn on the power, no interaction required. All of this can be built into a box of some sort, giving you an in/out effects setup. It's what I've done with several systems, although they are not as small as a real pedal. Any regular USB sound card will work. I recommend the Roland Edirol UA-25 o/ UA-25EX as it's a simple USB 1 sound device that will work with anything that speaks USB audio without a driver.

You get instrument jack/XLR preamps in and stereo out. Hey Dan (or anyone who feels compelled to answer), How does one use, say, the UDOO board similar to a pedal then? Doesn't a standard guitar effects pedal's input-jack accept instrument-level as well as output instrument-level at its output jack? I suppose you could reverse a DI on the output of the UDOO? (As well as a 1/8 to 1/4 adaptor out of that stereo jack.ugh.) Is that what one would do to have the PD-effected audio to go back into one's guitar amp? Thanks. This is gettin deep!

Re: [PD] using pd live (sans computer/laptop/raspberry pi)
Wow. That pdf is beyond awesome, Dan. On many different levels. Question about this part though: An attached direct box converts high-impedance signals to microphone level for connection to a stage mixing and amplification systems (and I guess my previous question still remains unanswered) I want to take line-level (which is low-level impedance, correct?) back to instrument-level so as to use the guitar amp. So how does one get one's guitar out of the UDOO and back into the guitar amp? I'm assuming the only way would be to take the stereo out from the UDOO and plug it into a DI running in reverse and, finally, back into the guitar amp. But it doesn't sound like that's what you're doing specifically. It almost sounds to me like you go into the 'house mains' sans amps on stage. Or am I missing something (wouldn't be the first time).

Well, this is why don't want to use the dinky 1/8 inch audio jacks on an onboard sound card and use a USB sound card with built in preamps which handle the impedance issues. Any better sound card will have balanced 1/4 inch jacks out, which is what my UA-25 has (or at least is what the block diagram on the top says). I've run these into regular guitar amps many times. So how does one get one's guitar out of the UDOO and back into the guitar amp? guitar -- soundcard neutrik 1/4+XLR combo jack -- stereo 1/4 balanced jacks out -- 1 channel into guitar amp Obviously you'll want to adjust the levels accordingly. I'd suggest getting a USB soundcard with hardware incoming preamp and outgoing volume controls. This is another reason why I've been using UA-25s.

Many thanks, Dan. I'll look into these options and get back to you then. On Fri, Mar 14, 2014 at 12:44 PM, Dan Wilcox danomat...@gmail.com wrote: Without a computer, no. Without a desktop or laptop computer, yes. An embedded computer (rpi or UDOO, for instance) can totally do this and that's what some of us have used them for. Simplest case is to setup the system, install pd with your patch, and write a script that is launched when the machine boots that connects to the sound card and starts pd. This way it starts immediately when you turn on the power, no interaction required. All of this can be built into a box of some sort, giving you an in/out effects setup. It's what I've done with several systems, although they are not as small as a real pedal. Any regular USB sound card will work. I recommend the Roland Edirol UA-25 o/ UA-25EX as it's a simple USB 1 sound device that will work with anything that speaks USB audio without a driver. You get instrument jack/XLR preamps in and stereo out. You could also get this setup with my Pd iOs app PdParty of Chris McCormick's PdDroidParty and a sound interface to your mobile device. For instance, I have an Alesis iODock for my iPad which gives me the equivalent of a UA-25. I've also had success using a UA-25 with a powered USB hub connected to the iPad via the camera connection kit usb adapter. Let me know if you want to beta test PdParty as it's currently not released on the App Store. Subject: Re: [PD] using pd live (sans computer/laptop/raspberry pi) I'll take this a bit further into newb-question territory. Are there any soundcards that output instrument level signals? This would allow one to use PD into a computer and then out of a computer similar to how one uses an effects pedal, no? On Fri, Mar 14, 2014 at 10:00 AM, Aaron L. elmaster...@gmail.com wrote: List. Total newb question Is there any way to encapsulate(?) a pd patch into some sort of hardware (pedal? something else?) allowing for no computers (e.g. no bootup, no load times, etc.) on stage? I can't imagine that there is but, hey, I have no shame.

Re: [PD] udoo board sound issues
I haven't run any latency tests, so that might be what I'm getting. If so, it's acceptable for what I do. From what I've read, guitar - effects - amp latencies are already closer to 20ms. Sorry I haven't gotten back to the UDOO and pulled the relevant scripts etc off of it yet. I'm trying to get a few things done before I head out of town for work the next 2 weeks. I might be abel to get to it Sunday, but no promises.

The dedicated USB controller makes these guys work as compared to an RPI where I can't get full duplex without tons of dropouts. I'm using a Linaro install which boots to the console and runs the PD through scripting. The speed is great as compared to my old wearable computer. 4 cores makes a difference. I had to recompile my kernel to add midi support, but that's working great. It's not too bad, actually. I also built Pd-vanilal from source which was pretty easy using ./configure + make. I also have a script which fetches externals and builds/installs the agains vanilla so I have the few externals I need. As with my previous experience running Pd + embedded Ubuntu, I get great performance with RT permissions, the -rt startup flag, and ALSA. Jack is needless
