PsiStore Write & PsiStudio Live Visualization Issue about psi HOT 2 CLOSED

[posted on behalf of @sjdent]

Hi Xiangzhi

For the size of the chunks (extents) being written, from your screenshot it looks like you’re writing 32MB extents, not 32kB extents, and this is correct for a 32-bit application. If your app was 64-bit then the extents would be 256MB each. With 256MB extents, I’m seeing new extents being created about every second, and with 32MB extents that number would be much higher.

You’re generating a lot of data because you’re writing unencoded color images to the store, so it’s possible that the out of memory condition you’re seeing is correct. If you could write encoded JPEGs instead of raw HD images, it would really cut down on your data rate and I think the issue should go away. Switching to a 64 bit application may help as well.

Thank you!
You are right, the main problem where there was too much written data was because I was writing the raw data to the file. Changing it to following fixed it.

kinectSensor.ColorImage.EncodeJpeg().Write("Image", store, largeMessages:true);

I believe the second problem ("Access to path XXX is denied") was probably because the mixed of 32 bit (Application) and 64 bit (Psi Studio). The problem went away after I changed my application to 64 bit. There seemed to be a problem with accessing stores from 32 bit application live with PsiStudio.
