FFmpeg and M3U8 Processing

FFmpeg Introduction

FFmpeg is an open-source multimedia processing framework supporting almost all audio and video formats. It includes powerful command-line tools for transcoding, format conversion, and streaming processing. FFmpeg is one of the most widely used tools in the streaming industry.

Core components: ffmpeg (transcoding), ffplay (playback), ffprobe (media analysis). These tools run on all major platforms including Windows, Mac, and Linux.

M3U8 Transcoding

FFmpeg can convert various video formats to M3U8/HLS format:

• Basic transcoding: Convert MP4 to M3U8 using -c copy to copy streams without re-encoding.
• Segment duration: Use -hls_time to set segment duration in seconds.
• Playlist size: Use -hls_list_size to set number of segments in playlist.
• Multi-bitrate: Use multiple outputs for different bitrate M3U8 streams.

M3U8 Analysis

FFmpeg's ffprobe tool analyzes M3U8 streams: view stream info (codec, resolution, frame rate, bitrate), segment info (duration, sequence numbers), and format info.

M3U8 Download

FFmpeg can download M3U8 streams: download complete video as MP4, download specific time segments, download and transcode simultaneously.
