Great video mate. So if I am recording and streaming I am using both cpu and gpu at the same time framebuffer both on cpu and gpu changes due to use case ?
That's a /great/ question!!! You're right on the money with the fundamentals: to record or stream, you need to get that memory out of the video buffer into somewhere else. How that happens, though, is up for grabs. A CPU can do it, to move it into regular memory (or a separate location if it's already there). OR, if some kind of DMA chip or the memory manager may be able to move memory from that framebuffer to the regular memory. There's no framebuffer on CPU really, but it'd be in regular memory vs video memory.

Nice explanation sir .I was looking for this type of video and finally I got it .thanks 👍
Welcome 👍
The way the scan line moves just like an old typewriter...interesting

you actually no need to write everything, otherwise nice informative presentation
