The string in my example is the string of digits. Yes, I would personally just use a row of toggles. It simplifies inputting values, I can't imagine anyone starting with a decimal representation of a binary string to define a rhythm, what they want is the other way around. are always 1 or 0 there won't be any problems with long strings. in theory this is correct. nevertheless, when saving a patch containing a string (this is: a symbol) 101, pd will eventually parse this as number 101.0 on re-loading the patch. therefore i proposed a truly symbolic representation. no, i don't think so. even though i haven't looked closely at your string-implementation (which really should be called blob rather than string, imho) I did it to see if it would work, the name is irrelevant to me. I guess as far as string implies text, it was a bad idea. The object manages a list of bytes, so they are strings in the c sense except there is no trailing zero, and in the Pascal sense except that the length is kept beside the string, not in front. The strings may be stored and read from files but they aren't saved in the pd patch except as arguments to the str objects. , i doubt whether it interferes at all with pd's saving mechanism which is the problem here (at least: which is the problem i am talking about). the internal symbol representation is an as truly symbolic representation as your strings are there are other problems with symbols, like the infinetely growing hash-table; this is (to my knowledge) somewhat addressed by your strings; but this has nothing to do with the problem of storing the token 01 in pd: at the best it will be stored as 01, but on loading the patch it will be become 1 (which might be appropriate, but might as well not). As I said, if it's stored as an argument to a str object, 0 0 0 0 0 1 with spaces in between the digits involves no symbols, only floats. Even if that gets converted to 0.0 0.0 0.0 0.0 0.0 1.0 it won't affect the meaning. The str object doesn't use symbols internally except for the [str tosymbol] variant.

If you wanted to use a creation argument, just use the [expr~] object by itself, i.e.: [expr~ $v1 2.7] or whatever. [expr] and [expr~] don't seem to be able to handle dollar-sign creation arguments, so you'd have to figure out another way to pass an argument, like: [loadbang] | [f $1] or something like that.

Re: [PD] lowering gem camera capture CPU overhead
Hi Ico, I've run into exactly the same problem. Most probably it is the decoding of the firewire signal that eats the cpu cycles. The dv format (same as firewire) is compressed into a 29 Mbits/sec stream (see e.g. http://www.adamwilt.com/DV-FAQ-tech.html#DVformats) that needs to be unpacked before processing in GEM (or any other video software). My solution is to use analog video cameras with a capture card. In this way I am able to use four simultaneous cameras using less than half of the cpu power on a standard winpc with pentium 4, 3GHz. I don't need much picture quality so I got really cheap surveillance CCD cameras costing less than 50 euro each connected to a four-input capture card (about 190 euro). Another great thing is that your are not limited in cable length as with firewire. Another solution would be to find a firewire capture card with built-in decoder (I guess there are such cards out there). /Anders Ivica Ico Bukvic wrote: Hi all, I've been trying to shave off precious cycles off the FW camera input capture. The problem is that vanilla capture of a FW camera feed (NTSC) already introduces 50+% of CPU overhead on an AMD64 3000+. I have experimented with lowered gem frame value, but anything below 20 seems to jagged. So, here are the questions: What is the cause of such a high capture overhead? Is there a way to minimize such overhead beyond just optimizing code for sse and other similar methods, plus the aforesaid frame option for the gem object? Many thanks!

[PD] create object dynamically
Hola list, this is my first post! i would like to know if is possible to create a object dinamically (for example from a list or something like that)? and looking for it in the list and google but i didn't found anything. it would be very cool! thanks Husk ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] GEM / pix objects : limiting colours
i found a workaround. if i insert a [pix_rgba] object before [pix_offset], it will work (doesn't work without your fix, so thanks a lot for it!). strangely the alpha channel is the first, followed by red, green, blue, so it's really ARGB not RGBA ...

Ah this is interesting - and proof that it's really time I learn dynamic patching ... your approach is probably more efficient, but on the other hard, my approach allows for lists of any length. (Although, I doubt that I'd be doing patterns longer than 64 very often.) Anyway, my point is that with dynamic patching perhaps it would be possible to use your approach, without knowing the length of the list in advance. ~David ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
