Re: [PD] RPi - GEM openGL
hello, if by from within PD you mean triggering omxplayer from pd you can do that either by using [shell] like Simon explained or by using pdsend and pdreceive, this could be done remotely, here is an how to : http://antoine.villeret.free.fr/?p=600 cheers a -- do it yourself http://antoine.villeret.free.fr 2013/2/15 João de Brito Rocha Reis Vidigal jbvidi...@gmail.com Simon, Your patch seems to be a GREAT simplification work of what I got. Thanks so much! I got the omxplayer working on the RPi from terminal... Perfect! however I can't get it to work from within PD! any suggestions?

Antoine did you check out xbmc further, I don't have a Pi here at the moment but have been looking at the xbmc docs and it can be controlled directly through a TCP port, so you should be able to do a lot more control (via netsend etc). Perhaps only the media centre playlist, looping and seeking stuff ... no crossfades that I can see. There does seem to be some provision for custom effects somewhere, via shaders but it seems, but probably only in GL, not in GL-ES. Still ... accurate seeking could be useful, there seems to be access to a global clock and seeks in files ... both with high enough resolution to sync things well. I'll test that when I can when I get a chance. Has anyone tried using pdp on a Pi? again, I'll have a play when I've got one here. Pdp has an xv window, and a movie player that uses the linux quicktime library ... is the quicktime library available for Pi? and if so does it use the built-in codecs? ... that could be a way to go for fairly straightforward video playback.

Re: [PD] RPi - GEM openGL
Ok... Hands on! I kinda need this... So guide me and I'll try my best! 1st - can I use pdp_xv on the RPi?... will it work? putting it very simply, the thing I need is really just a video window to throw some videos in... short videos and from time to time. meaning it is not a VJ machine... which it could be... but it ain't! 2nd - if not, so if there is currently NO WAY to have video coming out of PD in a RPi, where can I start to try an make it happen!? 3rd - I got a git account... I don't really know how to use it though!!! As I said before, give me a bit of guidance and I'll try my best to help on the development of this! thanks JV ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] RPi - GEM openGL
One place to start is to read thru the archives on this list, and the pd-dev and gem-dev lists, since this topic has been discussed quite a bit. There was one recent suggestion of trying to use a new library that makes it easier to port OpenGL apps to OpenGL ES. Trying to build Gem with that library would be a good thing to try. .hc On 02/13/2013 08:15 AM, João de Brito Rocha Reis Vidigal wrote: Ok... Hands on! I kinda need this...

It wasn't hard for her to get a screenfull of buttons to do the cues she wanted, and the Pis were great since she didn't have much time to set up in the venue, so her wifi network could be run and tested offsite. Plus the Pis worked out cheaper than buying long VGA cables etc. Anyway this worked for her .. obviously it is extremely limited, but it does let you play videos cued by pd. Just open pihelp.pd Now I want to get things a bit better, and see if I can put together a very simple set of pd objects to set up a window then play and crossfade a series of videos. Nothing fancy yet, but just getting that up will be a start. Unfortunately it can't happen too soon, I've got some other stuff on my plate too.

Could I ask you guys to check my patch?

[PD] RPi - GEM openGL
Hi guys. I'm almost back from the dead for what concerns this list... Well... I'm almost back from the dead for what concerns PD at all!!! Let's Just say that almost 3years have passed! Anyways, to my questions! Ok, so the issue, as pretty self explanatory as the subject of this email can be, has to do with the in vogue RPi. I have this old patch I built 3 years ago. At the time I was using an arduino to trigger some video/audio in PD. It's for an interactive video installation. So, I even bought a miniMac to work with it... Works just fine. However, I wanted to reduce/minimise the hardware... An besides after all this time, the miniMac became part of the well functioning of my house. So I thought: why not try to get this patch in a RPi? Got hold of one, read shit loads of stuff about it, prepared it, installed it, got PD in... So to realise that the bastard is not working. Damn... Read more and more. So it seems that this is a contemporary matter going on. GEM doesn't work on openGL ES... The thing is, I need a GEM window (or so I think!) to do this. Is there ANY work around this issue? Ideas? Plans? Jokes!!??? Thanks guys JV ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
