Hello, regarding gsvideo, the crash reported in the thread you mention is due to not reading all the video frames coming from the camera. It is a current issue with the lib, but it should be more stable when used normally.

thanks for your reply and the library
what do you mean with "when used normally" ?
i copied your code from your "Getting Started with Capture" demo
but i am capturing 640 x 480 pixels and mask the video with one image:

1. void draw() {
     offscreen.beginDraw();
     offscreen.image(bgImg,0,0);
     if (cam.available() == true) {
       cam.read();
       camImg = cam;
       camImg.mask(maskImg);
       offscreen.image(camImg,0,0);
       offscreen.endDraw();
       image(offscreen,0,0);
2.   }
   }
   

it seem that gsvideo-0.5.0.1. runs more stable so maybe i could use that version
is there a big difference in capturing performance between version 0.5.0.1 and 0.7 ?
i would like to capture 1280 x 720 pixel as the camera provides full hd but its to heavy for my cpu
and i cant find any working resolutions between 640 x 480 and 1280 x 720

best whishes

sorry, by normally I meant reading all the frames coming from the camera. In the tests I did, the problems were caused by the following code:

1. if (cam.available() && frameCount % 10 == 0) {
2.   cam.read()
3.   ...

Removing the "frameCount % 10 == 0" condition prevented the crashes from occurring.

Can you provide some more details about the stability of 0.5 vs 0.7? Did you identify under which circumstances the camera capture in 0.7 crashes? How often?

the crushes occur immediately in 0.7 when i capture pictures bigger than 320x240 and / or do some image processing
if the pictures are smaller and there is no processing it crushes irregular after a view seconds
version 0.5 seems to be stable

two other questions:
as build application (.exe) from with 0.5 the capturing doesn't work at all
empty fullscreen the camera doesn't get activated
application with fullscreen doesnt even show an window
i tried this with your "Getting Started with Capture" win demo

how can i find resolutions between 640x480 and 1280x720 ?

thanks + best

The version 0.5 cannot be used to generate exported applications, unfortunately.

About the instability using 0.7 with your camera, maybe you can try another capture plugin with GSPipeline, such as ksvideosrc. Something like this:

1. pipe = new GSPipeline(this, "ksvideosrc device-index=0 ! decodebin2 ! ffmpegcolorspace ! video/x-raw-rgb, width=1280, height=720, bpp=32, depth=24");

GSCapture in 0.5 used to use ksvideosrc, and I later switched to dshowvideosrc. Maybe this is the source of the crashes in your case.

i tried this:

1. pipe = new GSPipeline(this, "ksvideosrc device-index=0 ! decodebin2 ! ffmpegcolorspace ! video/x-raw-rgb, width=1280, height=720, bpp=32, depth=24");

 

the quality is quite noisy and the highest resolution i get is 640x480
i also tried it with dshowvideosrc instead of ksvideosrc
the quality is much better but it also doesn't let me grab bigger frames than 640x480 ;-(

thanks for helping

For the time being I'd recommend you try opencv to capture at the camera's native resolution. I'll do some testing as well, but maybe in a few weeks from now
