About: While configuring an RTMP, RTSP, or SRT input a fixed buffer with a default value is set, which can improve stream stability while struggling with fluctuating bitrates or unstable network conditions. This might be also helpful while handling non-CBR streams and using non-real-time systems (e.g. desktop computers, workstations).

Default values
The fixed buffer can be set between 0ms and 3000ms (10.000ms for RTSP). Live Video Cloud offers default values, which will serve most use cases:
- For RTMP push and pull inputs: 1000ms
- For RTSP pull inputs: 0ms
- For SRT listener and caller inputs: 250ms
When to use
If you are experiencing stuttering images, freeze frames, or inconstant bitrates, you might want to adjust the fixed buffer accordingly:
- Setting the fixed buffer to 0ms will turn it off completely
- Setting a higher value will increase the latency but can improve signal stability
- Setting a lower value will decrease the latency but can lead to a less stable signal
Hint: Changing a fixed buffer is sensitive and should be tested upfront under realistic circumstances to ensure a reliable ingest connection during production.
