RPi Video player was : Re: RPi - GEM openGL
by Antoine Villeret 17 Feb '13

17 Feb '13

hey Simon, I haven't check the JSON/RPC API of XBMC but yes I think there is some possibilty here Another way is to start with video player example like Ju said on his blog : http://w.xuv.be/projects/raspi_video_loop I'll give it a try next week and keep you aware. My goal is to be able to sync several RPi in a frame accurate way.

IR reverb and partconv~
by Pierre Massat 17 Feb '13

17 Feb '13

Hello, While readin Katja's website i discovered the [partconv~] object from Ben Saylor's library. I had actually used it long time ago with some IR reverbs, but I then judged the latency to big to be usable live. I gave it another shot this morning, and realized that the partition size could be set in [partconv~]. A lower partition size reduced the latency to something usable, which is cool, but it also cuts the tail of the reverb (it sounds very unnatural will low partition sizes). Could somebody please explain to me whether it is possible to fix this behaviour ? Cheers, Pierre.

Would this be a good substitute for GEM (in simple video playback terms!) on RPi? You guys mentioned something like it... I just didn't really get if yes or no!

Re: [PD] GPIO -> Python (pyata) -> PD ?
by João de Brito Rocha Reis Vidigal 15 Feb '13

15 Feb '13

OK! Got the object on!... However, I'm not quite sure of what to do with it now there is no help file on it. Besides, I didn't really get what meant when said: "basically you can use the "gpio" command to set the pins up" What command? Where in PD or terminal? Does it have anything to do with the RPi.gpio python package? Sorry... I'm an artist not really a programmer... I love this but I'm from another universe!

Hello I am setting up a Asus netbook for Pure Data/Gem/pidip and would like to not load the hoggish unity or even gnome seems to slow this little guy down. Can linux users suggest a window manager that might serve me best for this purpose. Thank you in Advance.

GPIO -> Python (pyata) -> PD ?
by João de Brito Rocha Reis Vidigal 15 Feb '13

15 Feb '13

Hi guys! Is it too stupid to assume that I can get control of the GPIO via python and send the data to PD via pyata!? All I really need is to read a pushbutton! tks JV
