[emmanuelgeoffray]

Hey there,
Is it working for other sizes than 640x480?
I'm trying the size mentioned here
but i get glitchy images
i'm on raspberry pi2
Thanks for your feedback,
Emmanuel

Hi Emmanuel,

I remember testing the 4:3 formats, but don't think I've tested the 16:9 formats.
Is there any way you can share an image of the glitches ?

Thanks,
George

hey,
thanks for your prompt reply.
I tested all the formats 16:9 and 4:3 with no success, except 640x480.
I'm far away from my raspi 2 now, but I can share screencaps on monday.
Best,
e

Here is an image of the glitches, with example-ofCvPiCam

Maybe it is an issue with the Mat not well recognized when using drawMat ?

I just tried with 1024x768 and the image is fine.
The image above is for 1296x972

I also get some scrambled display with drawMat() few days ago but this was with submatrix. (see kylemcdonald/ofxCv#163 for more)
And I sucessfully grab 1920x1080 frames but the drawMat() method is slow and it displays fullHD frame at 13fps.
Without displaying it, the grab runs at 60 fps (screen refresh rate) but I'm not sure to get only new image at this rate.
