Dear guys,

I created and HTTP stream from my local sound card to may other PCs using VLC.

Here is my syntax:

START vlc.exe -vvv dshow:// --sout=#transcode{vcodec=none,acodec=mpga,ab=256,channels=2,samplerate=44100}:http{dst=:8080/stream.mp3} --sout-keep --live-caching 100 --network-caching 100

It works very well, except the big delay on the other PCs when playing.
Do you have any ideas how this can be improved?

Thanks.

How big?

Reduce caching on the receiver.

delay is around 3 seconds
I have already tried to set --live-caching 100 --network-caching 100 on the receiver, but no improvements....

Well, there's also --sout-mux-caching on the server too. After that one, you will need to improve the code to further reduce latency.

thanks, with --sout-mux-caching 100 the delay seems to be only 1-2 seconds any more.
I also set --live-caching 100 --network-caching 100 on the client site, but no improvements....

Any other ideas?

Thanks.

As I said, you've reached the point where tuning parameters won't help. The code needs to be improved.

alright, what do you suggest?

Benchmarking and fixing the worse latency bottlenecks in the source code.

Did you try --clock-jitter=0? Not sure if it is relevant in your case but I think that without this option, the client might increase the size of the cache dynamically.
