Neither setting makes YouTube playlist transitions uninterrupted by itself: queues manage data inside a pipeline, while an application or source must manage which playlist item plays next. For fewer stalls, choose the queue that matches your pipeline, handle buffering messages appropriately, and tune watermarks against repeatable playback measurements.
What queue settings can—and cannot—do
A GStreamer queue separates upstream and downstream processing by creating a thread on its source pad. When a configured limit is reached, the pushing thread blocks until there is room. That can absorb fluctuations in incoming data, but it cannot fix inadequate network throughput, a stalled source, slow downstream processing, or missing playlist-transition logic. The GStreamer queue2 reference describes the queue behavior; the buffering design explains the broader buffering model.
The official GStreamer documentation cited here does not provide a YouTube playlist integration recipe. Treat playback inside one pipeline and orchestration between playlist items as separate engineering problems. Confirm how your particular YouTube source and application advance between items before making claims about gapless transitions.
Choose the element for the pipeline
Use queue2 for a single buffering point
queue2 supports buffer-count, byte, and time limits through max-size-buffers, max-size-bytes, and max-size-time. The GStreamer reference documents defaults of 100 buffers, 2 MiB, and two seconds; whichever limit is reached first governs. These are defaults, not universally optimal values for a particular network, codec, or latency target. Check the properties in the GStreamer build you deploy because the cited page does not specify a release number.

Use multiqueue for several related streams
multiqueue manages multiple queues and can dynamically grow queues within its limits to reduce the risk that one stream starves while another fills. It can continue pushing buffers on unlinked pads to support switching. Its documented maximum defaults are 5 buffers, 10 MB, or two seconds, whichever limit is reached first; the buffer count can grow depending on other queues’ fill levels. See the GStreamer multiqueue reference and verify the target build’s runtime properties.
For switching between streams, sync-by-running-time can throttle unlinked streams to the highest running time of linked streams, which the reference describes as useful for relinking without placing those streams in the future. Where downstream consumption differs, same-type streams can be grouped with a pad group-id. These are stream-coordination behaviors, not playlist-item selection or a guarantee of gapless playback.

Do not rely on unused or mismatched knobs
The multiqueue reference says extra-size-buffers, extra-size-bytes, and extra-size-time are currently unused; do not treat them as effective tuning controls. In either element, a limit that is too small can cause frequent blocking or rebuffering, while a larger limit can increase memory use and startup delay.
Handle buffering messages according to pipeline type
Non-live playback: pause while the buffer refills
For non-live streams, queue2 must have use-buffering enabled to report buffering progress. GStreamer’s application development guide describes low and high watermarks: reaching the high watermark produces a 100 percent BUFFERING message, and falling to the low watermark during playback can trigger buffering again. A simple policy is to keep the pipeline paused while buffering is incomplete and resume when the application’s chosen readiness threshold is met. The streaming tutorial illustrates resuming at 100 percent; that is an example policy, not a universal requirement.

More controlled applications can use buffering queries or estimated times to decide when to resume. The right threshold depends on the acceptable startup delay and the likelihood of network fluctuations.
Live pipelines: do not blindly apply the non-live policy
GStreamer’s buffering design says buffering messages in live pipelines usually indicate latency; applications generally do not change pipeline state in response. Do not copy a non-live pause-and-resume handler into a live pipeline without accounting for its timing and latency requirements.

Use multiqueue signals as diagnostics
multiqueue emits underrun when all its internal queues are empty, indicating starvation or upstream end-of-stream, and overrun when one queue is full. These callbacks run in a streaming thread. Use them as diagnostic signals and design callback work to respect streaming-thread constraints; avoid assuming they identify the root cause on their own.
Tune limits and watermarks with measurements
More prebuffering can make playback more resilient to network variation, but it delays the start and consumes more memory or storage. GStreamer’s buffering guide outlines approaches such as setting watermarks to represent a target duration using bandwidth estimates, using codec bitrate information when available, or beginning with a fixed buffer and increasing it based on observed time between rebuffering. Buffering can also be placed before a decoder so watermarks can be based on time.

Do not disable limits or set a very large time limit without considering bitrate, memory or disk behavior, and intended latency. The guide notes that queue2 can use a rate estimate with max-size-time; it does not prescribe one universal value.
Record enough to make runs comparable
For each repeatable run, record the GStreamer version, source and codec, bitrate or availability of a rate estimate, queue element, buffer limits and watermarks, startup delay, observed queue levels, and the number and duration of stalls. Change one relevant setting at a time and compare results against an explicit target, such as an acceptable startup delay or maximum stall frequency. These observations help distinguish a queue that is undersized from a source, network, or downstream bottleneck.
Queue limits, download buffering, and playlist transitions
queue2 can be configured to write buffered data to a temporary file, rather than relying only on memory. GStreamer’s buffering design says incremental download buffering depends on knowing the remote file length. Whether that behavior fits a YouTube source depends on the source’s capabilities and configuration; the cited documentation does not establish that every YouTube source supports it.
Neither a larger max-size-time, multiqueue, nor buffering-message handling alone selects the next playlist item or ensures a gapless transition. Find the item-advance behavior in the specific source element or application controlling the playlist, then test transitions separately from buffering within an item.
Or let it run in the cloud
If your goal is simply to keep uploaded videos playing as a 24/7 YouTube stream, rather than to build a GStreamer application, StreamNeo is a separate cloud option: upload a recording or build a playlist, add your YouTube stream key, and go live. Your computer and home connection do not have to stay on; it supports any uploaded quality up to 4K 60fps at one price per slot, and it automatically recovers if YouTube drops the stream.
