Description

The GStreamer rtsp-server has provided configurations that ensured a low
connection frequency but it was not possible to also receive up to date
decodable data.

By keeping an RTSP pipeline in the playing state after the initial DESCRIBE
request, the connection latency can be reduced. By conditionally forcing
keyframes, decodable frames are possible. This can be achieved by
manipulating the pipeline with pad probes, a useful skill to master.

Speaker bio Jacob Johnsson is an engineer at Axis Communications and a member of the multimedia streaming team where they develop the software responsible for streaming multimedia over networks. He enjoys low-level development, dogs and DnD.
