yt-dlpp

A thin wrapper around yt-dlp for parallel downloads

Description

yt-dlpp is just yt-dlp but starts downloads in parallel.
It supports passing multiple download URLs and unwrapping playlists.

Installation

Note: In addition to yt-dlpp, it is expected that you also have a valid yt-dlp install available in the command line.
Only Linux has been tested and validated, but feel free to open a PR to add support for other OS-es.

From pypi

pip install yt-dlpp

From source, on Linux

git clone https://github.com/GeoffreyCoulaud/yt-dlpp.git
cd yt-dlpp
python3 -m venv .venv
source .venv/bin/activate
pip install

Usage

yt-dlpp accepts all valid yt-dlp arguments and passes them mostly intact.
However, arguments related to CLI output will be ignored since that is handled by yt-dlpp.

Below, you can find a short list of the added arguments:

Argument	Description	Default value
--n-info-workers	Number concurrent url info extraction workers	Number of CPUs in the system
--n-dl-workers	Number concurrent download workers	Number of CPUs in the system

Architecture

yt-dlpp spreads the info getting and downloads to multiple worker processes. Here is an architecture overview of the project :

Reason to exist

As you may be aware, starting multiple Youtube downloads in parallel will probably not change the overall time taken, since a rate limit is in place, and before reaching it, you may simply reach your ISP's limit.
But yt-dlp (and therefore yt-dlpp too) is not only used for Youtube! Other websites have different restrictions, and some may simply allow downloads at a slow speed, but no per IP throttling (eg. NHK World Japan).
