Re: [PD] Re: more strange behaviours on 0.38.3
by Georg Holzmann 19 Jun '05

Hallo! > Im sorry for not being able to give any more info on these errors but they > seem totally random. The only thing i can add about this second bug is > that wish84's CPU use shoots up when this behaviour starts. I think this can be a PD-GUI problem. Maybe you are writing in an array very often or do something else, where the GUI needs a lot of cpu (use speedlim to avoid such problems ...) Then a lot of strange things can happen which drive you crazy if you try to debug them ...

gem pdp and yuv
by etienne deleflie 19 Jun '05

19 Jun '05

All, A couple of questions about Gem and pdp 1) does pdp work in RGB(A) only? 2) when Gem is in yuv mode, is it 24 bits per pixel .. or is it 16 bits per pixel, as in YUV4:2:2 .... where 2 adjacent pixels share UV data ? etienne

Hallo! > also glad to see you went ahead and did other colorspaces, but I do > wonder why you didn't use the GemPixUtils.cpp color conversion > routines? I think that it is better to use these so that we have a > "one-stop-shop" to concentrate all optimizations...I also have a little Yes - I can change that if it is better. I simply looked in gem2pdp.cpp and used the same conversion ... Maybe we should also change it in gem2pdp.cpp ? > quibble with "almost no cpu power", because this is basically an effect > that does touch every pixel, which can be quite something depending on > the size... of course ... :) - I meant compared to gem2pdp (and if you use YUV there is really almost nothing to do ...)

Re: [PD] very bad GEM performance

Hallo! > My card (Radeon M9) doesn't permit dri if I have dual screens. Maybe if > you check /var/log/Xorg0.log you'll see a similar warning. Thanks, I also have a ATI radeon: holzi@holzi:/var/log$ cat XFree86.0.log | grep DRI (II) Loading extension XFree86-DRI (WW) RADEON(0): Direct Rendering Disabled -- Dual-head configuration is not working with DRI at present. google says: The dri driver (ATI) does not support dual-head and 3d acceleration at the same time. If you're feeling adventurous, you should be able to get this to work with a patch, as long as both your screens don't exceed 2048 pixels in one dimension. But anyhow, I don't need it in the moment, I will try it when I need it ... :) LG Georg -- Geschenkt: 3 Monate GMX ProMail gratis + 3 Ausgaben stern gratis ++ Jetzt anmelden & testen ++ http://www.gmx.net/de/go/promail ++

HID object, woes.
by august 18 Jun '05

18 Jun '05

Hans, firstly, thanks a million for the hid device. it's something that is really appreciated. ...however, I am having some difficulties using it. I just built a USB device which you can see here: http://aug.ment.org/lechero I was about to present it yesterday, but was having some major problems with the [hid] object. I tested and built a patch with [hid] input on a desktop machine running gentoo, and it was working *perfectly* - fast, stable and clean. I had it running all day and was editing a running other patches at the same time. however, on my laptop running ubuntu, it was slow and cludgy, no matter how I set the polling. Whats also strange about this is that I changed the enumeration on my device so that 13 axis that I have show up properly in the registered abs_x, abs_y, etc. that you have in the 0.5 hid version. With the new enumeration, I can get [hid] to run and work perfectly on my desktop, however with the same code and with the same device, it crashes PD immediately when I turn the [hid] object on on my laptop. [a simple (if !=null) statement that I sent the other day will keep it from segfaulting, however. I just find it curious how it works on one machine but doesn't on another - I don't know much about USB] so, for the presentation that was scheduled, I needed a working solution on a laptop, ...and since everyone around me uses a mac, and since I thought you were developing [hid] for the mac, I decided to try it there. I downloaded your installer for PD with the hid object included, but to my surprise, the situation was even worse on the mac - the response from the [hid] object is _very_ slow and _very_ cludgy. I tried it on a coupla different macs, but got the same situ. In desperation I tried to set something up quick using supercollider on the mac, but the HIDdevice there was even worse. I'd like to help debug if possible, but I don't really know where to start. thats my hid story so far. -august.

Hallo Frank! Thanks for the fast answer! > Also you need to enable DRI in /etc/X11/XF86Config[-4] like: Ah - this is the problem. Yesterday I loaded my XF86Config-4 for dual screen and so I have this bad performance. But I don't understand why, I have the same settings (only an additional monitor:) - maybe I must specify something special for dual screen (xinerama) ? Here are my XF86Configs: http://grh.mur.at/XF86Config-4.dual_head http://grh.mur.at/XF86Config-4.single_head with the single_head DRI works ...
