How can I use Adaptive streaming for VODs in Ant Media Server?

I'm using Ant Media Server for streaming. My use case requires me to record the Live Streams as VODs so the users can access the content later as well.

Like the live streams, I want to apply adaptive settings to the VODs as well so that users can get the suited resolution as per their network.

I can't find any built in solution for this yet. Can you please tell me any solution as to how can I do this!

I'm using S3 to store the recordings.

Thanks.

Thank you for the question. As far as I understand from the question, it seems that Live Streams are recorded as VoD files.

I think the most efficient way is doing that through HLS. With this way, the VoD files are recorded as HLS and multibitrates is available. No need to transcode again and it'll be played directly. Let me explain this solution step by step.

  1. Set HLS playlist type to event and settings.deleteHLSFilesOnEnded to false . Edit your red5-web.properties for the application and set the following settings
settings.hlsPlayListType=event
settings.deleteHLSFilesOnEnded=false
  1. Restart the server
sudo service antmedia restart
  1. Add adaptive bitrates on the web panel.
  2. Start Live Streaming and let the Ant Media Server create HLS(m3u8 and ts) files for each bitrate.
  3. Stop Live Streaming

Then you can watch the stream by giving the master m3u8 file which is {STREAM_ID}_adaptive.m3u8. It can be even played directly by embedded player even if it's not live.

For more information, take a look at this wiki about HLS Playing

Please let me know if this approach helps you.
