Yes—Gyre says you can change the playlist while a YouTube stream is running. That is not the same as confirming that you can overwrite a particular file in place while it is playing, or that every replacement will happen without a gap. Prepare the new video, add it through the playlist workflow, and watch the stream’s health.
What Gyre says you can change while live
Gyre describes its playlist as the set and order of prerecorded videos sent into a broadcast, and says the playlist can be changed on a running stream. In practice, this supports adding or changing material without rebuilding the broadcast. It does not establish that replacing a stored file under the same name, especially one currently playing, is supported or gap-free. Gyre’s automation update describes the playlist operation, not every possible file-level edit.
Keep the two systems distinct: Gyre sends prerecorded video from its cloud service; YouTube receives an encoder feed. YouTube’s stream key identifies where the encoder sends that feed and allows YouTube to accept it. Changing the upstream playlist in Gyre is therefore different from editing a video already uploaded to YouTube. See YouTube’s stream settings guidance and encoder setup instructions.
How to change the video source with less risk
- Prepare the replacement first. Confirm that the file is complete and playable before relying on it in the live playlist.
- Check Gyre’s file status. Gyre says uploaded videos are checked and may need optimization before they can join a stream. Follow the status or optimization guidance shown for the file.
- Change the playlist in Gyre. Use the playlist controls while the stream is active. Treat this as a playlist change—not proof that an in-place overwrite of the currently playing file is supported.
- Monitor the YouTube event. Watch stream health and any review messages after the change. YouTube recommends testing before going live and monitoring stream health during the event; it does not prescribe a specific Gyre playlist-edit test. YouTube’s encoder settings guidance explains stream health and its handling of live feeds.
Why a replacement file can disrupt playback
Gyre warns that non-optimized files, or playlists that mix files with mismatched parameters, can cause buffering, fragmented delivery, interruption, or stream termination. This is vendor troubleshooting guidance, not a published failure rate for playlist changes. For its preparation advice, see Gyre’s video optimization guidance.

#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
- Do not add an unverified file at the moment it is needed; check its processing or optimization status first.
- Avoid assuming that a file with different technical parameters will behave identically to the videos already in the playlist.
- If playback becomes unstable, check the new file and playlist compatibility, then use YouTube’s stream-health information to distinguish a source issue from an encoder or connection warning.
Does the computer have to stay on?
Gyre describes its service as cloud-based, and YouTube lists Gyre among software encoder options for 24/7 prerecorded streaming. In this workflow, the stream is sent from Gyre’s servers, so your local computer is not the source machine that must remain powered for the cloud stream to continue. See Gyre’s prerecorded streaming overview and YouTube’s encoder guide.

If you want a YouTube stream to keep running from uploaded videos without keeping a computer on, StreamNeo is another cloud option: upload a recording or build a playlist, add your YouTube stream key, and go live. It streams the uploaded material to YouTube, not from a live camera. Nothing has to stay on at home; each slot streams the upload as made, up to 4K 60fps, at one flat price per slot, and it can automatically recover if YouTube drops the stream. The first day is free with no card. Monthly pricing is $9.99 per month. Learn more at StreamNeo, or start the free first day.
