Created: 2025-01-17 by UserComp.com Editors

M3U8 link with 10 different Streams (Video, Audio)

Context and Topic

This article provides a detailed context on the topic of using FFmpeg to grab specific Streams (Video, Audio) from an M3U8 link. It covers key concepts, subtitles, paragraphs, and code blocks, properly formatted according to the programming language, including indentation and tabulation needed.

Command

To achieve this, we will use the following command:

    ffmpeg -i m3u8_link.m3u8 -map 0:2 -map 0:3 -c copy output.mp4

Explanation

The command above instructs FFmpeg to grab Stream #2 (Video Stream) and Stream #3 (Audio Stream) from the provided M3U8 link (m3u8_link.m3u8). The -c copy option is used to copy the streams without re-encoding them. The output is saved as output.mp4.

Additional Notes

It's important to note that the current command-map option (0:) refers to the playlist. In this case, we are using the default playlist (0). If you have multiple playlists, you would need to specify the correct one.
