youtube-viewer-scripts

Here are some Bash/Perl scripts which allow to extend youtube-viewer functionality:

1. discogs_url_to_youtube-viewer_parser.pl - allows to specify Discogs.com album url to get a list of Youtube ID's in the list acceptable by gapless playback.
2. gapless_play.sh - uses a list of YT ID's to play music without gaps.
3. gapless_play_pause.sh - allows the play/pause currently used MPV player instance.
4. monitor_gapless_play.sh - displays in a separate xterm currently played song info.
5. gaples_play_next.sh - allows the current song to end.

The folder gp2 contains updated version which does not use youtube-dl script for caching the songs.

Dependencies:

These scripts depends on the following items:

a) youtube-viewer script has to be installed https://github.com/trizen/youtube-viewer

b) Perl modules are required for the discogs_url_to_youtube-viewer_parser.pl script:

HTML::Entities;
HTML::TreeBuilder;
HTTP::Tiny;

c) MPV player is used for playback

d) Bash and some standard Linux tools.

Usage

1. Put these scripts somewhere where your PATH can see them. :)
2. Modify the youtube-viewer.conf custom_layout to this:

  custom_layout_format  => [
                            {width =>  10,    text => "*TIME* \| ", align => 'right'},
                            {width => 13,    text => "*ID* \| "},
                            {width => 13,    text => "*PUBLISHED* \| "},
                            {width => '80%', text => "*TITLE*"},
                           ],

3. Run discogs_url_to_youtube-viewer_parser.pl <album_version_URL> to get a file with the album info. In case the file does not have the ID's you need to find them yourself as the maching mechanism might not find the album all the time.

4. Run gapless_play.sh <album_file.txt> to play the album music without gaps (it will run two instances of mpv, second paused but caching the next song).

5. You can bind some key combination to gapless_play_pause.sh in order to play/pause currently used MPV instance.

6. monitor_gapless_play.sh will be opened to display the currently played song info.

7. You can use the gp.sh script to run the playback with 3 windows (log, current song details, vim playlist with the cursor tracking current song):
