xruns in coll and msgfile and a question about the threaded external design
by Ivica Ico Bukvic 24 Sep '10

24 Sep '10

So, I looked further into msgfile and coll and found out whenever they try to do file i/o on files with moderate number of lines (or greater), e.g. 500+ lines, there is a guaranteed xrun when Pd is running with a small internal audio buffer (FWIW, all this has been observed on an atom computer where likely high cpu load threshold is more easily tripped and thus these problems are perhaps more apparent). Consequently this makes me wonder if it may be a good idea to adapt one of these objects so that they do file i/o in a separate thread? This brings me to my second question. Mrpeach tcpserver with recently submitted patches wraps broadcast call into a separate thread which is terminated as soon as a particular task is complete. One would think that this kind of a design should be better in terms of preventing audio xruns. Yet, in practice I've discovered that it still causes xruns fairly regularly, particularly when the computer is under load. OTOH, the disis_wiimote object developed as part of the L2Ork project which maintains a persistent secondary thread for triggering rumble and LED toggle calls to the wiimote never trips an xrun, no matter what the workload. By now you are probably wondering what is my question. Actually there are several: 1) If tcpserver's "spawn a secondary thread, execute, terminate secondary thread" is causing xruns but disis_wiimote's persistent secondary thread with mutex does not, does this mean that spawning threads is so taxing on the computer so as to cause the aforesaid xruns thus defeating the very advantage one is trying to generate by spawning them? 2) If answer to #1 is yes, is this because tcpserver's thread is one that detaches from the main thread? 3) if answer #2 is yes, is there anything one can do to lower the overhead of this breakaway thread? 4) could one ostensibly use persistent thread model from disis_wiimote on coll and/or msgfile in order to abate file i/o xruns? 5) if answer to #4 is yes, could the secondary thread call clock_delay()to provide a bang-on-read-complete (as the coll does) even though it is effectively running independently from the main thread without causing a major ruckus inside Pd's internal interrupt/clock that deals with audio and gui updates? Any help is most appreciated.

Pd-extended 0.42.5 re-release
by Hans-Christoph Steiner 23 Sep '10

23 Sep '10

There were a couple of omissions in the packages, so I have repackaged everything and posted it up on the downloads page. * If you are on Mac OS X or Windows, you should use the build from 2010-09-22 _not_ 2010-09-16. * If you are on Debian or Ubuntu, you should use 0.42.5-2 not 0.42.5-1. The new packages are also in the apt repository: http://puredata.info/docs/faq/debian * If you are building from source, re-download the tarball. This repackaging fixes: * missing help patches in 'mapping' and 'ekext' * /usr/include/pdextended/pdextended should be /usr/include/pdextended * /usr/lib/pdextended/pd symlink for pd~ * Gem and extra/bonk~ build problems in source package .hc ----------------------------------------------------------------- ----------- You can't steal a gift.

a little correction, then it would mean something...:) Using a table would be lighter in memory, and for cpu.

coll alternative
by Ivica Ico Bukvic 23 Sep '10

23 Sep '10

Does anyone have a good/practical alternative to the coll object? I've noticed some consistent xruns this object is causing when processing larger files (which seems surprising to me as operations it relies on should not be that CPU intensive). Also, does anyone have any idea what might be possibly causing the xruns within the object itself. Could it be perhaps File I/O operations or the fact that dump object generates tons of operations down the pipeline (despite the fact that all of those are pretty benign in and of themselves, amounting mostly to routing and minor processing of output)? Any thoughts would be most appreciated.

GEM Neupert Tutorial '10-av-more control'. How do I play more than 1 video?
by J bz 23 Sep '10

23 Sep '10

Hi all, Been sat here for the last couple of hours going round and round and I am stuck stuck stuck. I have recently come across the Neupert tutorials(attached patch based on 10-av-more control) which are excellent, miles better than my attempts for audio/video sync. Anyway I am very stuck with this problem: I want to play 3 avi.s which are in [pix_buffers]. 1 file plays fine but as soon as I add another pd crashes. I attach the patch.(av_plyr3.6) Not attaching the avi.s and audio as I guess it's pointless? they work seperately. My hunch is it's something to do with the [pixbuffer_filmopen] patch and/or the use of $0 but I just can't figure it out. Any pointers/fixes gladly received - deadlines looming etc... On a friends windows machine as it's super fast, so it's: windows 7 most recent pd-extended Very sure it's user-error though. Cheers, Jb

I'm trying to start a new stream with [pdgst]. I send [0 ( to [pdgst] and then a new message [location( to [gnomevfssrc] at the end of the first video stream. After, i send [1 ( to [pdgst] but get no stream. Do you know why ? Thanx. ++ Jack PS : evn with a bang message after [0 ( to [pdgst], it doesn't work.
