Glossary

This glossary provides definitions for common terms used throughout the Senta-streamer documentation.

FFmpeg

A complete, cross-platform solution to record, convert and stream audio and video. Senta-streamer manages FFmpeg processes to handle video stream processing.

Profile

A transcoding profile describes the command line for launching an FFmpeg process. Profiles allow applying the same settings to a group of streams and support variables for customization.

Stream

A video stream process managed by Senta-streamer. Each stream uses a profile and sets its own variables for input, output, and other parameters.

Transcoding

The process of converting a video or audio file from one format to another. This includes changing codecs, bitrates, resolutions, or container formats.

Variable

A placeholder in a transcoding profile (e.g., ${i} for input, ${o} for output) that can be replaced with specific values when creating a stream.

Process

An instance of FFmpeg running with specific parameters. Senta-streamer manages these processes, including starting, stopping, and restarting them.

Codec

A software or hardware tool that compresses and decompresses digital video or audio data. Common video codecs include H.264, H.265 (HEVC), and MPEG-4.

Container Format

A file format that can contain various types of data, including video, audio, subtitles, and metadata. Common formats include MPEG-TS, MP4, and MKV.

Bitrate

The amount of data processed per unit of time in a video or audio stream, typically measured in kilobits per second (kbps) or megabits per second (Mbps).

Resolution

The dimensions of a video image, typically expressed as width × height in pixels (e.g., 1920×1080 for Full HD).

Aspect Ratio

The proportional relationship between the width and height of a video image, commonly expressed as 16:9 or 4:3.
