NAME

yt-dlp-play - Download videos with yt-dlp *and* play them while downloading

VERSION

This document describes version 0.001 of yt-dlp-play (from Perl distribution App-YtDlpUtils), released on 2024-07-09.

SYNOPSIS

Usage:

% yt-dlp-play [OPTS] <URL_OR_VIDEO_ID>...

Examples:

% yt-dlp-play       https://www.youtube.com/watch?v=hoKvtNawdS8
% yt-dlp-play -f 18 https://www.youtube.com/watch?v=hoKvtNawdS8 ;# force 360p mp4 format
% yt-dlp-play -f 22 https://www.youtube.com/watch?v=hoKvtNawdS8 ;# force 720p mp4 format

DESCRIPTION

You want to download a video but want to see it while it downloads (and of course do not want to download it twice)? This is a wrapper for yt-dlp which does the following for each argument:

  • Run yt-dlp with --get-filename

    To get the output filename, first this is executed:

    % yt-dlp [OPTS] --get-filename <URL_OR_VIDEO_ID>

  • Run yt-dlp that outputs to stdout and pipe it to mpv

    % yt-dlp [OPTS] -o - <URL_OR_VIDEO_ID> | tee <OUTPUTFILENAME> | mpv -

Some caveats:

  • The media-player program mpv as well as the tee utility are required

  • Each command-line argument must be a video ID or video URL, not a playlist URL

  • You should not request a format that does not stream

    For example, if you specify -f 135+140 (merging of video-only 720p MP4 and audio-only AAC stream) you will have to wait for yt-dlp to download the whole video & audio streams and merge them before getting the video to play.

  • If you specify multiple URL's, you cannot go forward to the next video or backward to the previous

    In mpv you can use ">" or "ENTER" to go to the next video in the playlist, or "<" to go backward to the previous. You cannot do this using this script because the URLs are streamed individually one-by-one with separate invocation of yt-dlp and mpv.

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

% prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
