Re: [PD] pd-extended crashes sending data to SSR with tcpclient
Hi Iain. To be honest, I didn't think about the problem that a message could need more than one packet. It's good to know that iemnet/tcpclient can handle that. @IOhannes: thanks for the suggestion. And (binary) 0 is indeed the terminating character. On Mon, Jul 1, 2013 at 10:14 PM, Iain Mott m...@reverberant.com wrote: Using iemnet/tcpclient and implementing IOhannes parsing suggestion, my patch is now communicating with SSR without crashing. There is a bogging down problem though and testing with just 3 sources, I need to keep the limit at 10 messages/sec for each. It stops working at higher rates but doesn't crash. SSR is running on this local machine and there is no WiFi involved. Unfortunately I don't think UDP is an option with SSR. No sorry, not for now. But feel free to hack into the SSR code! SSR also sends XML level data to tcpclient constantly for each source in the scene. Perhaps this extra traffic isn't helping. eg. updatesource id='1' level='-98.5405'/source id='2' level='-99.8139'/source id='3' level='-99.6628'/source id='4' level='-101.127'//update I'll wait to hear back from SSR to see if they have any suggestions. I guess you are talking to me ... There is one quick and hackish way to avoid the level messages: Go to src/boostnetwork/connection.cpp (around line 102) and remove the line _subscriber.send_levels(); ... and recompile. This should get rid of the annoying level messages. The SSR still sends all other messages, but if desired you can disable them in a similar manner. I'm aware that this isn't a satisfactory long-term solution, but for now it may help. We have big plans to modularize the network interface of the SSR in a way that different network protocols can be used interchangeably, e.g. WebSockets, FUDI, OSC, ... MIDI could probably also be included there. In addition, we want to implement a publish-subscribe mechanism (for all protocols which have a back-channel) which allows clients to select the exact amount (and probably rate) of information to receive from the SSR. However, currently we just don't have the resources to make these changes. @list: if anyone wants to help feel free to contact us: s...@spatialaudio.net!

It's already limiting the rate to 10 messages every second for each moving source and so far I'm only using 4 sources. This rate, done for testing, is already less than ideal. Each location message sent SSR for a given source looks something like the following: requestsource id=1position x=1.234 y=-0.234//source/request Does this seem excessive?

You'll have to resize the width of the GOP box manually, which means you have to listen for changes to the string length of the label and _guess_ at how many pixels that translates to. If you guess wrong (and given that different OSes do fonts differently you will guess wrong) it will break. Every modern GUI toolkit (even tk) assumes that the developer doesn't want to worry about these problems, or at least assume they only want to control them at a much higher level. For some context: Pd's diagrams actually break all the time: whenever patch authors set up objects so that the wires to/from a secondary xlet are either straight or at 45-degree angles. Those lines may not be at the same angle on someone else's machine, because of font rendering peculiarities on the OS or specific font settings that user has made. The breakage can actually introduce ambiguities that aren't there on the original author's machine, but most of the time these breakages just degrade the diagram gracefully-- you get not-quite-straight lines that don't look as aesthetically pleasing but the patch is fully functional/editable. If your iemgui label or symbol box on a GOP canvas goes over the allotted pixel width of the GOP rectangle you lose functionality because the object no longer moves with the GOP canvas. If you're making a one-off GUI for your own purposes this may be fine, but if you're trying to make a reusable abstraction, don't combine auto-resizing widgets with geometry-unmanagers. They don't degrade gracefully, and the pitfalls aren't trivial to see unless you stream the patch to three different OSes at the same time and watch the differences. -Jonathan ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] Raspberry Pi USB2 audio fixed (apparently)
Hi all, I did a fresh install of Raspbian using the NOOBS installer. The pd-extended package from puredata.info doesn't work with my soundcard (it wasn't working before). And Pd vanilla installed from the Raspbian repositories doesn't work with it either (although it was working fine before). My soundcard is an old EMU 0404 USB. By doesn't work I mean that it either throws an Audio stuck/closing audio error, or simply freezes everything (Pd, LXDE, mouse, everything) and all I can do is unplug the power chord. So for me not only did it not fix anything, but i'm actually worse off and left with the inability to use Pd at all on my Pi. I haven't tried Miller's compiled version of Vanilla yet (I still don't know how it is different from the one available in the Raspbian repos).

Re: [PD] Raspberry Pi USB2 audio fixed (apparently)
Hey Pierre, Damn that's rubbish! Have you checked that pulseaudio is uninstalled?

Yeah, this is what I assume as well, though I don't have any data to back up that assumption. On the other hand, serializing might be cheaper on the C side than in Pd. I just cannot think of a use case where you actually want to directly use those chunks as received. Either you need to delimit packets, then you need to serialize the data, or you actually need a stream, but then you also need to serialize the data. * It gives you the false impression of dealing with packets when you in fact are dealing with a stream.

It might be useful to consider this when thinking about the best way to send the data (e.g. one byte per packet is not efficient, and you might get the false impression that TCP doesn't work very well). Since the TCP stack is free to packetize the data in the most efficient way, the application layer does not have to, or even _must_ not consider chunk size of data. This should be handled transparently by the transport layer. When the application transmits thousands of 1-byte chunks, the TCP layer will most likely send them as bigger chunks over the network. From the application's point of view, TCP is _exactly_ behaving like a serial link (just without a clock). And as I always say, UDP is probably a better choice for what you are trying to do, if it involves real-time control, with UDP you _do_ have control over the packet size. Agreed.

Re: [PD] GOP text field / symbol which is resizeable? (was: GOP text field which sends bang?)
[symbol\ | [label $1( | [cnv] - (ATTN: Ivica) [hsl] seems to have the bounding box (?) miscalculated in l2ork so it doesn't GOP when it's less than 2-3px from the border of the parent canvas. Checked in Vanilla, it works as expected ([hsl] can be placed to the very border and it will GOP). According to Ivica this is on purpose. The reason is that iemguis used to have miscalculated positions and pd-l2ork fixed that while pd-vanilla/pd-extended didn't. Unfortunately, this breaks compatibility between pd-l2ork and pd-vanilla/pd-extended. Roman This is true. Although, I wouldn't call translating an object by 3 pixels exactly breaking compatibility. I do agree it is a nuisance nonetheless, yet I feel it is a necessary part of pd(-l2ork) growing and becoming more consistent. The reason why I did what I did in pd-l2ork is best portrayed if you use autopatching option which positions everything in line vertically. If you autopatch objects like atom, then hsl, then another atom (or symbol or simply an object), you'll see how things align (or don't). Now, if an object does not render properly in pd-l2ork because of this translation, then what is needed is simply nudging it in the opposite direction. However, if the object appears within the GOP boundaries but is still not visible in GOP window, then there may be some stale things I missed in the getrect call for hsl. In this case, please do file a bug report. Best wishes, Ico ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
