how to reduce the time gap in the streaming

[luctuf]

Hi to all! It's possible to reduce the 7/8 seconds time lag when I stream audio and video?

Is your Video out of sync or are you refering to the delay between server and client?

server client delay can be reduced by : Preferences -> Input & Codec Settings -> Default caching policy.

Audio Delay Up/down Shortcut k/j

Thanks for the reply! Audio and video are perfectly sync, the problem is the delay between the server and the client (on the same LAN): it's possible to stream with less than 7 seconds of delay? I set the default caching policy to "Low latency" and the stream start with 4/5 seconds of delay...it's possible to further lower this delay?

This is a huge delay, which sould not be caused by vlc. Altough i read a post of a dev that vlc isn't made for "live streaming"
if i understand that right, realy low latency is not achieveable by vlc so far.
Can you give some information about your settings (streaming and network) maybe "transcoding" is active?

But if you want to watch movies in sync on server and client you might try the "network synchronisation" feature.

Preferencecs, "Show all [x]" -> Advanced -> Network Sync

On Server: Network Master Clock [x]
On Client: Master Server Ip: "ip.of.your.server"

Hi! Sorry for the lag!
So: the transcoding is active, I've try to disable it but if I do that, I can't stream anymore...it's normal?

I've to send an audio/video stream coming live from a webcam: I've seen that another webcam have a minor delay...it's possible that the webcam I use is not good for stream?

Thanks in advance!

I'm also having a 4/5 second delay. I'm streaming from a Hauppauge WinTV-HVR-1150 card. The client and server are on same LAN. Here's my command line:

Code: Select all

cvlc v4l2:///dev/video0 :input-slave=alsa:// :v4l2-input=1 --mms-caching 0 --sout "#transcode{vcodec=WMV2,fps=5,vb=800,scale=1,acodec=wma2,ab=128,channels=2,samplerate=44100}:http{mux=asf,dst=:1234/}" --no-sout-rtp-sap --no-sout-standard-sap --sout-keep

What are some changes I can make to see if I can reduce the delay?

Thanks!
