Minimalistic Youtube Looper at https://yt.aergia.eu
The most basic loop is one video with optional range:
#v=<videoId>[&t=<start>[;<end>]]
Time format is 1h2m3s or just a number of seconds.
YouTube-compatible syntax is also supported, enabling use by a simple domain swap in URLs: ?v=<videoId>[[#|&|:]t=<start>[;<end>]]
Advanced Loops
A YouTube video can have more than one interval. Intervals are chained with the + sign:
#v=<videoId>&t=<start1>;<end1>+<start2>;<end2>+...
To chain intervals from multiple videos just append another &v=(...) at the end of URL:
#v=<videoId1>&t=<start1>;<end1>+<start2>;<end2>&v=<videoId2>&t=<start3>;<end3>+<start4>;<end4>`
YouTube Playlist Import
To generate v=(...) items from <playlistId> and start autoplay from <n>-th element:
#list=<playlistId>&index=<n>
YouTube URLs are supported transparently: if <videoId> is inside of the playlist specified by <playlistId> on <n>-th position, it will be deduplicated:
#v=<videoId>&list=<playlistId>&index=<n>
If URL already had some videos <n> will be recalculated.
Video Quality
To cap video quality at a preferred level (global setting):
&quality=<level>
Current list of available levels can be found in YouTube Player API Reference.
By default image is displayed forever (useful for GIFs). A slideshow can be created with simplified t parameter:
#i=<imageId>.jpg[&t=<displayTime>]
Example: https://yt.aergia.eu/#i=cJjBEQP.jpg&t=3s&i=vo9DPpp.gif&t=3s
Note: GIF intervals are automatically rendered as GIFV.
Single track interval:
#s=<user>/<sound>[&t=<start>[;<end>]]
Example: https://yt.aergia.eu/#s=sacredbones/pharmakon-body-betrays-itself&t=0s;17s
Playlists (sets) are lazy-inlined on first play:
#s=<user>/sets/<set>
Example: https://yt.aergia.eu/#s=erasedtapes/sets/erased-tapes-collection-iv
Similar to YouTube Player - main difference is format for videoId.
Currently, to be detected, videoId has to begin with http and end with: .mp3, .mp4, .ogg, .ogv or .webm.
Example: https://yt.aergia.eu/#v=https://vt.tumblr.com/tumblr_npa1dkYP1U1urdxm4.mp4&t=4s;5s
Random Mode
&random
This parameter will force playback of all intervals in semi-random order (normalized random: current interval will not be played twice in a row).
Playlist Editor
&editor
This parameter will force playlist editor to be visible from the start.
