m3u8_download #

Why have this project #

I want to download some video, but use ffmpeg -i xxx -c copy xxx.mp4 is too slow.

Because it seems that there is a limited speed for single-threaded downloads, the overall speed is very slow, and online playback will freeze, but multi-threaded downloads will not be very slow. So I wrote this tool, which can parse m3u8 and download ts files in multiple threads, and do the "merging" work locally to speed up.

require #

The executable is available for Windows, Linux and macOS.

And, you need to install ffmpeg first.

Install #

dart pub global activate m3u8_download

git clone https://github.com/CaiJingLong/m3u8_download.git
cd m3u8_download
dart pub global activate -s path .

Or, download from release

# after download
chmod +x m3u8

Usage #
