Video lag in ProtectLivesteam

[j4zzcat]

Describe The Problem:
I'm using the unifi-protect package to stream the video of a single camera to ffmpeg and product HLS video (this format is suitable for consuming via a web page). There's a lag of about 15 seconds in the video - is this normal?

To Reproduce:
Followed the docs for listening to the message events of ProtectLivestream. I'm feeding these directly into ffmpeg stdin (i.e., -i pipe:0) for transcoding into HLS. I'm watching the transcoded stream with VLC.

Mea culpa. The lag is introduced by HLS.

There is no lag. It’s used in my homebridge-unifi-protect plugin and it livestreams video with sub-second latency just fine. It’s also used by the native UniFi Protect webUI to show livestreams.

I won’t troubleshoot your FFmpeg challenges (well beyond the scope of support I provide), but your issue is there, not with the API or this library.

Enjoy! Glad you tracked it down.
