I can't change the Resolution for another Application, but i can use the Software(btw. Logitech) to record movies / make snapshots with a resolution i choose. If i'm capturing from PD then i can only adjust Brightness, Gamma, Focus... etc with the Tool. regards, markus > > mfgadrs > IOhannes _______________________________________________ Pd-list(a)iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

Fwd: pix_video dialog / dimen is not setting anything under windows
by Markus Demmel 10 Jan '11

i misclicked and send this mail to the PD-List first. Sorry for that. i just use the same folder for both... -------- Original-Nachricht -------- Betreff: pix_video dialog / dimen is not setting anything under windows Datum: Mon, 10 Jan 2011 23:47:38 +0100 Von: Markus Demmel <az(a)zankapfel.org> An: pd-list(a)iem.at Hi, i have bought a new Webcam with lots of pixels inside... (720p@30fps / 1080p@15fps) but i can't change the resolution. It seems to be stuck at 640x480. - If i send the dialog message a receive a long list of possible settings, which fits to the camera, but i can't click apply and if i click on ok, nothing changes. - sending a message e.g. "dimen 1280 720" also doesn't work The Vender Tool just enables me to set Brightness/Focus etc... so any ideas, how to change the capture resolution? Regards, Markus PS: I need the Windows ATI Drivers for GLSL-Shaders, otherwise i would work with linux.

pylon driver and latency
by cyrille henry 09 Jan '11

09 Jan '11

hello, i just tested the new pylon driver for the Ethernet camera. it work well. i've got few rendering problem, but it's the same than with the official application. i think it's because my computer can't do jumbo frame. about latency, i noticed that most latency comes from the rendering part, and not the capture. things are lot's better for the rendering using single buffer mode. here is an image filming the screen. number shows ms, not frame. (screen is at 60fps) So, i'm very happy... Cyrille

Gem, pix_video and Plugins
by Jack 03 Jan '11

03 Jan '11

I don't know the new plugin method to make [pix_video] working. When i open help about [pix_video], i get : error: [pix_video]: no video backends found! ... you might be able to track this down from the Find menu. And when i create the gem window and start render, i get : error: [pix_video]: do video for this OS Any help will be appreciated ;) I see a 'plugins' folder in 'src' and when i cd in 'videoV4L2' and enter : aclocal ./configure make I get : checking how to hardcode library paths into programs... immediate ./configure: line 14318: GEM_CHECK_RTE: command not found ./configure: line 14327: syntax error near unexpected token `v4l,' ./configure: line 14327: `GEM_ARG_WITH(v4l, video input, force)' make: *** [config.status] Erreur 2 I missed something ? What i have to do to use my webcam ? Thanx. ++ Jack

Category: None Group: None >Status: Closed Priority: 5 Private: No Submitted By: Cyrille Henry (nusmuk) Assigned to: Nobody/Anonymous (nobody) Summary: add control to uvc devices on linux Initial Comment: most webcam are using uvc driver on linux. this drivers allow control over diferents parametters of the camera (lighting / gamma / etc). it would be nice to be able to control this parametters from a Gem patch. by example, to be able to remove auto luminausity is very important for tracking... ---------------------------------------------------------------------- >Comment By: SourceForge Robot (sf-robot) Date: 2010-12-22 21:20 Message: This Tracker item was closed automatically by the system.
