Questions[icecast](ubuntu)

I have kodi (installed from the repos) as a mediaplayer on top of Ubuntu AMD64 18.04, and would like to stream whatever audio is being played on it to an icecast stream on my LAN, so that individual Raspberry Pi's can pick it up and play it in the different rooms in my house.

I have icecast installed on the mediaplayer PC and see the home screen on my.lan.IP.address:8000 from other machines on the network so that part is working.

What I can't seem to get to work is picking up the audio output and sending it to Icecast2. I have Darkice installed, it uses hw:0,0 as its input. I tried setting the input to "pulse" but that gets refused as a connection.

I start darkice with sudo privileges in order to get a low nice value to avoid stuttering. The effect of that is that it complains I do not have rights to the Home directory. It does not tell me which Home, or what it needs it for -there is no /home/something configured in the darkice config file. I use /tmp/dump.ogg for the dumpfile.

All the guides on the web are either deprecated or are aimed at different usecases (playing individual files instead of picking up an existing audio stream).

Can someone please guide me in the correct direction?

I've just tried setting up Icecast2, alongside with Darkice.

I notice that when I play from the live stream, the audio seems to be 30 seconds later than it should be.

How do I make a Icecast live stream play at the same time as the audio it's providing? I understand that a lot of live streams are not always accurate, such as online radio but is there a feature when I can get the most accurate time?

Any help will be appreciated.

I found an internet radio station, but I would like to re-encode it to Opus 32kbps to fit on my unlimited data plan. How would I achieve this?

The source radio uses MP3 @ 160kbps, which is over my unlimited data bandwidth of 128kbps.

I need a console streaming client for icecast which allows me to use dynamic playlists and can play mp3. Ices2 support dynamic playlists but it plays ogg only, it does not support mp3 files.

I have successfully installed icecast and darkice on my ubuntu machine and was able to stream live on my lan. but to my disappointment it has a 15sec to 20sec delay.This is very poor performance. I don't think it is because of my lan connection because even when i tried to listen in that same ubuntu machine there was still a delay!

I have tried to configure icecast to have no burst-size which means there will be no buffering,this helped me reduce the delay to around 6sec to 8sec. So please if you have any suggestions or very good configuration values it would be of great help to me.

P.S the format i am streaming is mp3. someone suggested that i should use opus codec but i don't think icecast or darkice support it. and i am streaming in firefox using the html5 audio tag.
