Low-Latency DASH and HLS streaming
OvenMediaEngine supports HTTP based streaming protocols such as HLS, MPEG-DASH (Hereafter DASH), and Low-Latency MPEG-DASH with CMAF (Hereafter LLDASH).
OvenMediaEngine will support Low-Latency HLS in the near future. We are always keeping an eye on the decision from Apple inc.
Configuration
To use HLS, Dash and LLDash, you need to add the <HLS>
and<DASH>
elements to the <Publishers>
in the configuration as shown in the following example.
CrossDomain
Most browsers and players prohibit accessing other domain resources in the currently running domain. You can control this situation through Cross-Origin Resource Sharing (CORS) or Cross-Domain (CrossDomain). You can set CORS and Cross-Domain as <CrossDomain>
element.
You can set it using the <Url>
element as shown above, and you can use the following values:
Streaming
LLDASH, DASH, and HLS Streaming are ready when a live source is inputted and a stream is created. Viewers can stream using OvenPlayer or other players.
Also, you need to set H.264 and AAC in the Transcoding profile because MPEG-DASH and HLS use these codecs.
When you create a stream, as shown above, you can play LLDASH, DASH, and HLS through OvenPlayer with the following URL:
If you use the default configuration, you can start streaming with the following URL:
https://[OvenMediaEngine IP]:80/app/<stream name>_o/playlist.m3u8
http://[OvenMediaEngine IP]:80/app/<stream name>_o/playlist.m3u8
https://[OvenMediaEngine IP]:80/app/<stream name>_o/manifest.mpd
http://[OvenMediaEngine IP]:80/app/<stream name>_o/manifest.mpd
https://[OvenMediaEngine IP]:80/app/<stream name>_o/manifest_ll.mpd
http://[OvenMediaEngine IP]:80/app/<stream name>_o/manifest_ll.mpd
We have prepared a test player that you can quickly see if OvenMediaEngine is working. Please refer to the Test Player for more information.
