So, here's some another issue I'm having getting pd running smoothly on linux. I've got a Logitech Quickcam Pro 4000 and kernel 2.6.3 which has the pwc (phillips webcam (also for the logitech 4000)) kernel patch. I can plug in the camera, fire up camstream and the camera works fine and dandy. However, in Gem, trying to texture the pix_video to a sphere:
[gemhead]--[rotateXYZ]--[pix_video]--[pix_texture]--[sphere]
I don't get any texture, just the white sphere. I tried pix_videoNEW and pix_texture2 and doing a [pix_pix2sig~]--[pix_sig2pix~] in there, and none of that changed anything. When I start rendering I get this feedback, which would seem to mean it's working except maybe the last line: //begin GEM: Start rendering pix_videoNEW: starting transfer starting transfer cap: name Logitech QuickCam Pro 4000 type 1 channels 1 maxw 352 maxh 288 minw 160 minh 120
picture: brightness 31744 depth 24 palette 15
channel 0 name Webcam type 2 flags 0
setting to channel 0 buffer size 304128, frames 2, offset 0 152064
wanted format is 0x1908 setting cmcapture to 160x120 5 now trying standard palette 15 frame 0 0, format 15, width 160, height 120
GEM: pix_video: Opened video connection 23 vmmap 82A2364 VIDIOCSYNC: Invalid argument //end
The kern.log shows positive seeming feedback, saying the following when I stop rendering:
pwc Frame buffer underflow (21825 bytes); discarded. pwc Closing video device: 212 frames received, dumped 0 frames, 1 frames with errors.
On a subsequent try it said only
pwc Closing video device: 23 frames received, dumped 0 frames, 0 frames with errors.
As usual, any help, even a pointer in the right direction, would be greatly appreciated.
Thankyou, Ian Smith-Heisters
It may be that your texture is not a power of two - try 127x127 or 64x64. Martin

in recent versions of Gem the texture-size doesn't need to be power of 2 any more (when using [pix_texture]) for older versions of Gem [pix_texture2] (which is now an alias for [pix_texture]) did the job for non-power-of-2 images.
btw, 127x127 is non-power-of-2 too ;-)
unfortunately i don't know where the problem is (esp. when the [pix_pix2sig~]+[pix_sig2pix~] trick doesn't work either)
what does [pix_info] say ?
