GstRtspSink - Audio+Video Streaming Plus H264 Single Streaming

Follow Us On

This example mixes one combined audio and video mapping with a second independent H264 mapping. It is useful when one client needs the full program while another needs video only.

Example use case

A product can publish:

one full audio and video stream for normal playback
one video-only stream for analytics, monitoring, or lower-complexity clients

Server-side Pipeline

The following pipeline sends two different streams: a H264+AAC in-sync stream and a H264 only stream, through two different mappings: av_stream and v_stream respectively. Any of them can be accessed independently.

PORT=12345
MAPPING1=/av_stream
MAPPING2=/v_stream

gst-launch-1.0 rtspsink name=sink service=${PORT} \
v4l2src ! queue ! videoconvert ! x264enc tune=zerolatency ! h264parse ! capsfilter caps="video/x-h264, mapping=${MAPPING1}" ! sink. \
alsasrc ! voaacenc ! aacparse ! capsfilter caps="audio/mpeg, mapping=${MAPPING1}" ! sink. \
videotestsrc ! x264enc tune=zerolatency ! h264parse ! capsfilter caps="video/x-h264, mapping=${MAPPING2}" ! sink.

Summary

This mixed layout is useful when different client classes need different media compositions from the same pipeline.
