Win64 ScreenRecorder (Example code, UPDATED)

[encryptor256]

Hello!

This is Win64 ScreenRecorder.

Reasonable quality at reasonable size.

I was looking on the net for a simple srceen recorder,
didn't found, so,
then i decided to make my own.

I was inspired by Evan's AVICapt. http://www.evanolds.com/sc_main.html
He also provides source code for his screen recorder.
He made it in C++ builder.

But,
all programming i did,
i did on my own, collecting,
learning information from web's, so, nothing here is just a clean copy paste.

.Win64_ScreenRecorder:

Default frame rate is 30, assigned automatically.
Default file name, created automatically.
And it works too!

First i created, it, in Pelles C, because i wanted to be sure, that recorder, on Win64, actually works, and it did.
Then i translated, it, into NASM.

Hello!

This is Win64 ScreenRecorder, using NASM and GoLink.

I get rid of gcc garbage, which produces large size application, so i went for new linker GoLink.

This new version uses GoLink, which produces exe size only: 9.50 KB (9,728 bytes)

Win32's?
It might be easier to translate back to win32's.
But, you can do it, on your own.

Your cmd to assemble the updated version is incorrect. It must be:

Code: [Select]

nasm screenrecorder.asm -f win64 -o screenrecorder.obj
