Why Does Castr Stop Playing Videos in a YouTube Playlist?

Castr playlists and YouTube playlists use different players and controls. Identify the player, then check autoplay, next-item, or loop settings.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

First check which player owns the playlist. Castr’s documented playlist feature plays Castr livestreams and video-on-demand content; Castr’s YouTube guide covers sending a Castr stream to YouTube, not playing a YouTube playlist inside Castr. The right fix depends on whether playback stops on load, between items, or at the end of the list.

Identify where the playlist is playing

Look at the player URL or app where playback stops. If it is a Castr playlist player, use Castr’s playback options. If it is a YouTube playlist, use YouTube’s controls on that device. A Castr stream being sent to YouTube is a separate setup and does not mean Castr is playing a YouTube playlist.

If it is a Castr playlist

Castr’s playlist feature sequences Castr livestreams and VOD content. Its Playback options include separate controls for starting playback, moving to the next item, and repeating the list. The help article describing this feature was published May 31, 2026: Castr Help Center.

  • Stops before playback starts: Check Autoplay on load. Castr’s playlist player URL can also start playback when ?autoplay=true is appended.
  • Stops after one item: Enable Autoplay next item in the playlist’s Playback options.
  • Stops after the final item: Enable Loop to restart the playlist after it reaches the end.

Castr’s embed player API separately documents an autoplay=on|off parameter for starting a Castr embed on load. That parameter controls the Castr player; it is not a YouTube playlist setting. See the Castr player API documentation.

If it is a YouTube playlist

Use YouTube’s Autoplay control to play a related video after the current video ends, and the playlist Loop control to repeat the playlist. They do different jobs: Autoplay advances to another video, while Loop restarts the list. YouTube says Autoplay settings may vary by device and notes that it may stop after inactivity.

  • Check that Autoplay is enabled on the device where playback stops; do not assume a setting on one device carries over to another.
  • If playback ends at the list’s final item and should begin again, enable the playlist’s Loop control.
  • If it stops after a period of inactivity, check whether YouTube’s inactivity behavior applies rather than treating it as a Castr playlist setting.

See YouTube’s official help for Autoplay and looping a playlist.

If Castr is streaming to YouTube

A Castr-to-YouTube connection sends a Castr stream to YouTube; it is not the same workflow as playing a YouTube playlist in Castr. Castr documents connecting YouTube through an API connection or YouTube’s stream server and key. Its setup guide also recommends turning a destination off while the stream is offline and enabling it again when the source is live. That guidance concerns the stream connection, not a confirmed explanation for playlist playback stopping. See Castr’s YouTube setup guidance.

When the settings do not fix it

The available platform documentation explains controls and setup, but does not establish a specific cause for an individual playback failure. Before asking support, note the player URL or app, device, when playback stops (on load, between items, or at the end), and any error message. Those details help distinguish a player setting from a connection or account-specific problem without assuming an outage or defect.
