|
- Through log files of icecast2 called access.log we can see how many listeners listened to our events
|
||
|
|
- Darkice is more easy, flexible to use than ices.

How to's/ streaming homebrew style:
|
||
|
|
|
||
|
|
On the server:
|
||
|
|
- install icecast:
|
||
|
|
$ sudo apt install icecast2
|
||
|
|
- fill in the hostname: yourdomain.tld
|
||
|
|
- fill in the passwords
|
||
|
|
- $ sudo iptables -A INPUT -p tcp -m tcp --dport 8000 -j ACCEPT
|
||
|
|
- follow this (from Basic Configuration): https://things.bleu255.com/runyourown/Streaming_Service_with_Icecast#Basic_Configuration
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
On your computer:
|
||
|
|
|
||
|
|
- install darkice
|
||
|
|
|
||
|
|
$ sudo apt install darkice
|
||
|
|
|
||
|
|
Run Darkice with any config file
|
||
|
|
# Having jack as input is better for sound quality
|
||
|
|
# Not so much in terms of sound quality but in options of combining different
|
||
|
|
# programs (such as jamin, mpv, mplayer and incoming audio from devices)
|
||
|
|
|
||
|
|
Setup that I use now (Crunk)
|
||
|
|
audio sources(like hardware or mplayer) ---> jack ---> jamin (monitor audio levels) ---> jack
|
||
|
|
---> darkice ---> icecast
|
||
|
|
|
||
|
|
|
||
|
|
- download an example configuration file: http://w-i-t-m.net/darkice_varia.conf
|
||
|
|
- change the settings in the .conf file
|
||
|
|
- install a tool to loop your current soundcard audio as output, such as:
|
||
|
|
- pulseaudio volume control (Linux)
|
||
|
|
- don't forget to open port 8000 on your router (maybe better to open another port like 8001?)
|
||
|
|
- Ready! Run it with this command:
|
||
|
|
|
||
|
|
$ darkice -c mysettings.conf

tracktitle.innerHTML = title;

Experiences streaming video (luke&simon):
|
||
|
|
icecast can do video! woot woot
|
||
|
|
icecast + https is a bit tricky (to hide the source password)
|
||
|
|
anyone can load a film into VLC and connect to icecast to stream (but it only supports certain file types like webm and so on. A lot of good quality films come in proprietary formats like mkv (i think) and you need to convert them though)
|
||
|
|
you can pipe output from ffmpeg straight to icecast, see https://raw.githubusercontent.com/nwgat/scripts/master/icewebm.sh (this works! but the video bombs out after a while...)
|
||
|
|
video streaming is fucking black magic and i have no idea what i'm doing
|
||
|
|
me and simon are trying to get our 200 films out of the hard drive but not just a link dump, we want to socialise through programming films together
|
||
|
|
|
||
|
|
fucking hell this person is a wizard https://stackoverflow.com/questions/47509316/ffmpeg-mp4-to-webm-through-icecast-server-livestream this seems to be the key to ascending into piracy nirvana
|
||
|
|
|
||
|
|
ffmpeg -i lajetee.mkv -acodec libopus -b:a 64k -vcodec libvpx -b:v 500K -crf 25 -vf scale=640:360 -content_type video/webm -loop 365 -g 10 -keyint_min 10 icecast://source:foobar@place.com:8000/lajetee.webm
|
||
|
|
|
||
|
|
(hacking on it @ https://git.autonomic.zone/decentral1se/stream.hbbs.decentral1.se/src/branch/master/stream.sh)
|
||
|
|
|
||
|
|
So, like, this seems to work for some period of time with a few watchers. When someone tunes in it is not clear if they join at the same time!? It was bombing out before I added the magic "-g 10 -keyint_min 10" (again, not a fucking clue what is going on) but it seems to work for at least 2 people so far.
|
||
|
|
|
||
|
|
subtitles need to be added in somehow? unknown how to do that
|
||
|
|
my laptop is maxing out 2 cores streaming this 2.2gb mkv file (ffmpeg is converting it to webm on the fly for the stream!? wtf is going on really i don't know) so it seems like this streaming would take out your laptop over time.
|
||
|
|
|
||
|
|
The stream maybe bombed out after like 20 mins I think but maybe it was because I edited the file by accident. I am not sure but it seems like there are some reliability issues to sort out here.
|
||
|
|
|
||
|
|
Next day:
|
||
|
|
streamed out total recall for 3 people and it was laggy and the CPU was 100% while streaming (1 core)
|
||
|
|
chatted with crunk about this, we need to investigate hardware requirements to know what we need to have
|
||
|
|
we need to investigated bandwidth requirements to know how much we can support
|
||
|
|
aiming for <= 5 screens (multiple people behind screens!) as the first milestone with non-laggy watching
|
||
|
|
maybe ffmpeg+icecast is not the one true solution
|
||
|
|
obs supports streaming: https://obsproject.com/wiki/Streaming-With-SRT-Protocol#general-overview (SRT!)
|
||
|
|
next step: come up with some calculations based on research/discussisions on what are the hardware/network requirements for doing streaming for a few screens and decent quality so that we can plan for the next step
