MPEG-DASH Live Streaming Latency Decrease
Vraag van · 02-11-16 om 13:38 ·Hello,
on behalf of my company i am currently evaluating the capabilites of MPEG-DASH live streaming for a video conferencing application.
My testing environment is a LAN in which a ffmpeg-encoded live stream is sent via rtmp to the Wowza Engine.
The engine is configured to transrate the video into different renditions and to provide the MPD. On the client-side the stream is shown either by Shaka Player or Dash.js hosted by a webserver.
After tuning the parameter of the MPEG-DASH Streaming Packetizer property there is still ~ 6 seconds latency between sender and receiver.
ffmpeg command used:
ffmpeg -f dshow -i video=”webcam name” -vcodec libx264 -g 12 -r 24 -f flv rtmp://server-ip:1935/live/myStream
MPEG-DASH Streaming Packetizer configuration:
mpegdashChunkDurationTarget 500
mpegdashMaxChunkCount 5
mpedashPlaylistChunkCount 5
Custom:
mpegdashMinimumUpdatePeriod 500
Is there any way in the Wowza Streaming Engine to lower the latency below 1 second?
A few people have achieved such low latency by using fragmented transfer of the video segments to the client.

Is anything like this possible with Wowza?
Thank you in advance
