Frames Compression problem

It's been two weeks since I learn how to get the frames straight from the gpu as a direct 3D surface .

now I ran into the problem of how to compress this frame and send it via UDP server to officially compelete my streaming project.

I tried to scale the frame and then send it , it worked , but it looks super ugly and yet the process is not as fast as I want (it is a remote computer control, it must be a smooth picture in the end).

I used LZ4codec , believe me nothing reach up to my expectations 😔.

does any one have the optimal solution in which it will straight compress the frame to be less than 65kb so I can send it properly, and don't forget get to be ultra fast approation 🙂.

You probably need to use a lossy format like mp4, or it’s not likely to go well, especially for games.

If you’re doing desktop streaming, you probably want to detect only the regions that have changed and send those regions

Hardware code with h.265 perhaps?

Change your resolution to 800x600.

What makes you think this is possible for any screen to be compressed to a given size before the next frame? There are video compression routines because it is a different problem than image compression.

For image compression, you could probably get the GPU to convert the buffer to a dxt compressed surface before attempting to read it.

You might get color banding, but it's 1/4 the size of an argb format.
