GstRtspSink - Live File Streaming

Follow Us On

This example uses a file-based source while still exposing it as an RTSP stream. It is useful for demos, replay workflows, validation, and systems that need to publish pre-recorded content through the same RTSP interface used for live feeds.

Typical uses

Demo environments
Regression testing
File replay through the same RTSP workflow used in production
Simulating a live source when hardware is not available

Server-side Pipeline

The following pipeline takes a MP4 file containing an H264 video and an AAC audio elementary stream and streams them through RTSP using GstRtspSink.

PORT=12345
MAPPING=/stream
FILE=/var/media/videos/recording.mp4

gst-launch-1.0 rtspsink name=sink service=${PORT} appsink0::sync=true appsink1::sync=true qtdemux name=demux \
filesrc location=${FILE} ! demux. \
demux. ! queue ! aacparse ! audio/mpeg,mapping=${MAPPING} ! sink. \
demux. ! queue ! h264parse ! video/x-h264,mapping=${MAPPING} ! sink.

Summary

Live file streaming is a practical way to test client interoperability and product behavior before a real camera or hardware source is available.
