How to Convert HEVC MP4 to HLS Stream with ffmpeg

HEVC (High Efficiency Video Coding) is a popular video compression format that offers high-quality video playback with smaller file sizes. MP4 is a commonly used container format for storing video and audio streams. HLS (HTTP Live Streaming) is a streaming protocol that allows you to deliver video content over the internet in small chunks.

If you have a HEVC MP4 video file and you want to convert it into an HLS stream, you can use ffmpeg, a powerful and versatile command-line tool for video and audio processing. In this article, we will guide you through the process of converting a HEVC MP4 file to an HLS stream using ffmpeg.
