Hello,
I've been browsing through the PD_list archive and it seems that the following questions are still unanswered. (And I'd like to hear some discussion from PD users about it)
What is the best way to run a live video feed through GEM on a Windows XP machine? (or any windows machine for that matter?)
Is there a 'best camera' to use? Should it be USB or other? (Logitech or Intel USB quickcams?! or should a person use coaxial 'surveillance' cams?)
If pix_video doesn't work properly in Windows (as explained in an earlier PD-list message), what other objects can be used to display live video feed?
In past discussions, there is mention of pix_video not running properly in Windows because of Windows' particular method of naming video devices. I haven't seen any other messages in the archive which clearly say, "I am using 'x' camera with 'x' video capture card with GEM (or other library) and IT WORKS!." Instead, most of the messages I've read only explain problems or incompatibilies.
I ask these questions because I'm interested in purchasing a camera (but I don't know WHICH camera will undoubtedbly work with GEM on Windows XP) and displaying live video in the GEM window along with various other GEM creations. Does anybody have experience with this?
Many thanks Dave Sabine

Yes, it would be great to know of a working setup. I was hoping to use my firewire input w/ my Sony DVMC-DA2 analog to DV video convertor. Alas, firewire input doesn't work with GEM. If I'm wrong, someone *please* tell me! I'd love to put it to use.
Any hope for firewire access in Gem or Framestein? That would be wonderful.
curious too, Sam
How far off is the possibility of using pix_movie (or a variation) like pix_url, using the quicktime lib, in order to tune into a quicktime stream? One could then stream video directly into PD over network... has other intertesting possibilities as well. :)
Started with the Externals howto this week, what a way to start back into C! arg!

quicktime definitely has this capability, and i would think that the win API has the same features as the mac one in this regard. instead of calling NewMovieFromFile the call is NewMovieFromDataRef, so it's easy to integrate into existing quicktime code.
i have no idea if it's possible to fake this on linux, but since the quicktime streaming server (qtss) runs on linux, the libs for creating a stream and possibly decoding it might be available.
also there is the possibility to stream directly out from an app to a server now. i have some example code for this, but it states that it only works on the mac. perhaps a linux hack from GEM to the qtss could be done??

I am having a problem with editing the xsample (xgroove.help.pd) I added a plugin~ northpole and a schroeder reverb but when i reopen the patch it cannot re-connect the patch here is teh patch for windows

even copying the whole patch and pasting it into a new patcher destroys the xgroove~ object Pat Pagano, Director South East Just Intonation Society http://www.screwmusicforever.com/SHREESWIFT/ ----- Original Message ----- From: shreeswifty ppagano@bellsouth.net To: pd-list@iem.kug.ac.at Sent: Friday, May 31, 2002 7:32 PM Subject: [PD] xsample trouble

Hi Joge, were you working under linux or Windows? (which pd version?) I heard of problem with conflicting gcc versions under linux, but not of such problems under Windows.
thanks, Thomas

i was working under windows 2000 at the time with version .35 test 17 i believe .. but since the update to 0.2.3 of xsample everything started to work as it should [ie all the patchcorded connected when i load a patch containing xgroove]. i am tring to run xgroove 0.2.4 in windows xp with pd .35 test 24 , however i am having a prblem with pd hogging up all the cpu . this problem is not related to xgroove in particualr i dont think because pd is hogging the cpu even when it has no patches open . i am getting about 30-40% use of pd.exe process on my p3 750mhz laptop .
i am thinking it might be my graphics driver but i am also thinging it might just be the new build of pd ... have to check into it some more ..

Very stange! Which pd version are you using? (although i can't test it at the moment because of a hard disk problem...)
Can you create one of the xsample objects in a patch once other externals have been loaded?
greetings, Thomas

USB and IEEE1394 have limited cable lengths (ca. 4.5m). This can be extended with the use of a hub or repeater. This may outrule USB and IEEE1394 in some applications.
ADSTech makes a IEEE1394 webcam that works without compression. Has anyone used this cam?

clarification: Gem does (still) NOT support IEEE1394 (eg. firewire) devices. i have finally got new hardware (various ieee1394-cards), so i will soon (but maybe not today or tomorrow....) be able to start the pix_dv thing again
people used to make USB-cameras working (at least under linux) i have none so i have no possibility to try.
then, i have never managed to make my bttv-capturecard work with Gem under w2k (i am not that expert on win32-platforms, but i never had any problems under nt and 9x) since i do not receive flaming emails about "w2k-support for bttv", i guess that all other users have it running.
personally, i really like the "'surveillance'-cams" since they are so cheap

i have yet to find a working driver for an old intel bttv card in win2k. the jokey m$ wizard tries to install a suitable driver on every boot, but it never works. i tried two drivers from the web and neither works in GEM (locks up on loading the pix_video object). if anyone has a working win2k bttv driver i'd be happy to try it.
