Alexa Camera audio lag in rtsp playback

Hello

I've setup a RTSP mp4 stream which is played perfectly with VLC, video and audio in sync.

But when streamed to Echo Show or Echo Spot there is a lag of over 10 seconds...

What is the reference implementation of a RTSP server to test with?

I know live555 is rather old (as their website is as well ;o) and will probably never support mp4 containers.

Hi Davorin,

There are a couple of options.

1) Live555 is a functional RTSP server that can support sending audio and video over TCP with TLS
2) Wowza is a functional media engine that can support sending audio and video over TCP with TLS
3) gst-rtsp-server is a robust RTSP server powered by a battled tested media framework (Gstreamer)

Regards,

Tsuneki
