Videoroom plugin rtp_forward VLC

[Davide Caldelari]

Hi,

I managed to set up the videoroom plugin with the rtp_forward feature in order to see the stream in VLC.

My question is very simple: is it normal that the stream I watch in VLC has a latency of 1-2 seconds compared to the original stream? Or maybe I'm doing something wrong?

Here's the command I use to forward rtp:

{       request" : "rtp_forward",

        "room" : 1234,

        "publisher_id" : xxxxxxxxxxx,

        "host" : "127.0.0.1",

        "audio_port" : 60000,        

        "audio_pt" : 111,

        "video_port" : 60002,

        "video_pt" : 100,

}

In VLC I use a sdp:

v=0 o=- 0 0 IN IP4 127.0.0.1

 

s=RTP Video

 

c=IN IP4 127.0.0.1

 

t=0 0

 

a=tool:libavformat 56.15.102

 

m=audio 60000 RTP/AVP 111

 

a=rtpmap:111 OPUS/48000/2

 

m=video 60002 RTP/AVP 100

 

a=rtpmap:100 VP8/90000

 

a=fmtp:100

 

packetization-mode=1

Thank you very much for any suggestion.

Davide

VLC has default input buffer as I remember

VLC has a lot of internal buffers so it's not really designed for realtime decoding and playback. For lowest latency video try switching to mpv with --untimed option.
