Showing Buffer Full Issue During 4k@60fps Screencapture with FFmpeg on CORE i5-10500TE

Using CORE i5-10500TE (16GB RAM) Processor: Trying (Video) Screen Capture 4k@60fps using FFmpeg

Have you ever tried to capture your screen in 4k resolution at 60 frames per second (fps) using the FFmpeg tool? If you have, you might have encountered the "buffer full" issue. This article will focus on this topic and provide a detailed explanation of the key concepts involved, including FFmpeg, 4k resolution, 60fps, and the "buffer full" issue. We will also provide a solution to this problem, using a CORE i5-10500TE processor with 16GB of RAM.

FFmpeg: An Overview

FFmpeg is a free and open-source software project consisting of a vast software suite of libraries and programs for handling video, audio, and other multimedia files and streams. It is widely used for tasks such as format transcoding, stream encoding and decoding, metadata manipulation, and more.

4k Resolution and 60fps: What Does It Mean?

4k resolution refers to a horizontal display resolution of approximately 4000 pixels. This resolution is commonly used in digital cinema and high-end computer monitors. 60fps, on the other hand, refers to a frame rate of 60 frames per second. This means that the display is refreshed 60 times per second, resulting in smoother motion and less motion blur.

The "Buffer Full" Issue

When trying to capture a screen in 4k resolution at 60fps using FFmpeg, you might encounter the "buffer full" issue. This occurs when the input buffer (where the captured frames are stored) becomes full, and FFmpeg is unable to process the frames fast enough to keep up with the incoming data. This results in dropped frames and a lower overall capture quality.

Solution: Using CORE i5-10500TE (16GB RAM) Processor

To solve the "buffer full" issue when capturing a screen in 4k resolution at 60fps using FFmpeg, you can use a CORE i5-10500TE processor with 16GB of RAM. This powerful processor is capable of handling the high data rates and processing requirements of 4k@60fps capture, and the 16GB of RAM provides plenty of memory for the input buffer. Here is an example command code for capturing a screen in 4k@60fps using FFmpeg on a CORE i5-10500TE processor:

This command uses the gdigrab input device to capture the desktop, sets the framerate to 60, and the video size to 3840x2160 (4k resolution). The h264\_nvenc codec is used for encoding the video, and the preset is set to "slow" for better compression. The output is saved in an MP4 container.
