Zhaofeng Li | Interesting, just got to my laptop and tried https://brainmelter.brockman.news/brainmelter.ogg, and it looked just like an regular http request (not rtmp and stuff). But I do see https://github.com/aswild/icecast-notes so the main problem looks like that it's not "typical" http? | 15:03:56 |

HLS resembles MPEG-DASH
| 15:04:00 |
emily | yes, I named like four separate protocols | 15:04:03 |
matthewcroughan | And ffmpeg can do mpeg-dash as well? | 15:04:29 |
n4ch723hr3r | should | 15:04:41 |

MPEG-DASH is a technique for streaming video over the Internet. MPEG-DASH uses HTTP and can run on any web server.
| 15:04:53 |
matthewcroughan | By "run on any web server" does it mean "be transported via" ? | 15:05:01 |
matthewcroughan | it doesn't mean that the webserver is playing the role of ffmpeg | 15:05:11 |
emily | it can do all but one of the protocols I named and several more besides | 15:05:10 |
emily | none of this is really on-topic for this room btw… | 15:05:21 |
matthewcroughan | So you're saying liquidsoap itself can act as the server? | 15:05:52 |
matthewcroughan | So all I'd need is NGINX + Liquidsoap, rather than mpd + icecast + nginx for example | 15:06:32 |
matthewcroughan | What, networking and protocols? | 15:06:44 |
n4ch723hr3r | https://github.com/mbugeia/srt2hls
this seems to do what you want | 15:07:39 |
n4ch723hr3r |
srt2hls use Liquidsoap to receive a stream and encode it in HLS, then it use [nginx] (https://www.nginx.com/) to serve HLS content.
| 15:07:47 |
matthewcroughan | If the metadata is better supported by mpeg-dash, I'd rather be using that instead of hls | 15:09:53 |
matthewcroughan | turns out BBC radio actually uses mpeg-dash for everything | 15:10:09 |
n4ch723hr3r | you can probably use the liquidsoap file and mod it from HLS to mpeg | 15:10:59 |
n4ch723hr3r | so you should probably read into liquidsoap config/scripting | 15:11:43 |
emily | channel topic: "Declaratively manage your switching, routing, wireless, tunneling and more." | 15:18:00 |
emily | this is all application layer stuff | 15:18:32 |
toonn | I do understand the assumption that there's an intersection of interests. Are there popular alternative venues where generallly knowledgeable networking nerds hang out? | 15:37:33 |
hexa (clat on linux when) | #sysops:nixos.org | 15:39:49 |
hexa (clat on linux when) | maybe | 15:39:51 |
matthewcroughan | sadly no one in there | 15:57:55 |
