I added WaitWindowEvent() inside the main loop.

500 ms and it was no longer laboring, but I can't have video at 2 frames per second. I can delay it no more than about 29 ms and it still labors.

I commented out all the "Plot" commands. Didn't make much difference.

I understand Intel CPU's run hot ...

I added this to my main loop:

event = WaitWindowEvent(29)

It didn't help very much. CPU consumption dropped by about 1%, from 18% to 17%.

Note that the delay can't be longer than about 33 ms in order to make the desired 30 fps frame rate.

My CPU is an Intel Core i7, apparently not powerful ...

This is a big Windows 10 project to ask help for.

The program uses ESCAPI to read a webcam and display the webcam's image in a small window. It also draws a video waveform monitor.

The problem I'm having is that the program makes my computer labor and causes the cooling fan to race. CPU ...

Better?

How is this?

I was reluctant previously to left-shift a 16-bit varaible.


Global red1.u = 1023
Global green1.u = 1023
Global blue1.u = 1023

Global red2.u = 1023
Global green2.u = 1023
Global blue2.u =1023

;RGB10p32
Procedure.q RGB10pa32 (red1, green1, blue1, red2, green2, blue2)

sampleP.q = 0 ...

What is the aim of RGB10p32() and rgb10() ?

Did you read the web page I linked to? It gives two formats: packed and non-packed. The pixels MUST conform to either of those formats. Note that there are unused bits.

Hello -

I am starting to work with 10-bit color (10 bits each red, green, blue, no alpha. I have written two procedures to encode r, g and b values into packed and unpacked 64-bit quads.

Could somebody please check my code? Does anyone have a faster, more efficient way of doing this?

Here are the ...

You are referring to 30bit depth images, not to 10bit.

10 bits per channel.

There is also 12 bpc.

Requesting support for graphics with > 8 bits per channel (RGB) depth.

Existing functions could be modified like so:
10- and 12-bit depths are starting to be used in video and high-end graphics.

I can't get this to return the values I think it should.

I am trying to plot a pixel with R-G-B 940-940-940


img = CreateImage(1,100,100,24)

StartDrawing(ImageOutput(1))

Plot (50,50,RGB(940,940,940))

color = Red(Point(50,50))

Debug "Red "+Str(color)

color = Point(50,50)

color = Point(50,50 ...

Can PB handle 10-bit images, either on screen or in a file?

This would include RGB() and all similar 2D graphics functions.

I have fixed the bottleneck that was giving me a slow frame rate. I made a lookup table for gamma and eliminated the floating point. Will post the source code later.

I didn't read your post
But next is a simple way to switch between the 2 Window
Adapt it for your need

If InitSprite() = 0
MessageRequester("Error", "Can't open screen & sprite environment!", 0)

I got it to work, sort of. Here is the code. You will need escapi.pbi and escapi.dll

The problem now is that in full-screen mode, there is tearing in the first 50 - 100 scan lines when the subject moves. If I switch to #PB_Screen_WaitSynchronization the frame rate drops to an unacceptably low rate ...
