@zhaofeng:zhaofeng.liZhaofeng LiInteresting, 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
@matthewcroughan:defenestrate.itmatthewcroughan

HLS resembles MPEG-DASH

15:04:00
@emilazy:matrix.orgemilyyes, I named like four separate protocols15:04:03
@matthewcroughan:defenestrate.itmatthewcroughanAnd ffmpeg can do mpeg-dash as well?15:04:29
@n4ch723hr3r:nope.chatn4ch723hr3rshould15:04:41
@matthewcroughan:defenestrate.itmatthewcroughanhttps://www.cloudflare.com/learning/video/what-is-mpeg-dash/15:04:48
@emilazy:matrix.orgemilyhttps://ffmpeg.org/ffmpeg-all.html15:04:53
@matthewcroughan:defenestrate.itmatthewcroughan

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:defenestrate.itmatthewcroughanBy "run on any web server" does it mean "be transported via" ?15:05:01
@matthewcroughan:defenestrate.itmatthewcroughanit doesn't mean that the webserver is playing the role of ffmpeg15:05:11
@emilazy:matrix.orgemilyit can do all but one of the protocols I named and several more besides15:05:10
@emilazy:matrix.orgemilynone of this is really on-topic for this room btw…15:05:21
@matthewcroughan:defenestrate.itmatthewcroughanSo you're saying liquidsoap itself can act as the server?15:05:52
@matthewcroughan:defenestrate.itmatthewcroughanSo all I'd need is NGINX + Liquidsoap, rather than mpd + icecast + nginx for example15:06:32
@matthewcroughan:defenestrate.itmatthewcroughanWhat, networking and protocols?15:06:44
@n4ch723hr3r:nope.chatn4ch723hr3rhttps://github.com/mbugeia/srt2hls this seems to do what you want15:07:39
@n4ch723hr3r:nope.chatn4ch723hr3r

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:defenestrate.itmatthewcroughanIf the metadata is better supported by mpeg-dash, I'd rather be using that instead of hls15:09:53
@matthewcroughan:defenestrate.itmatthewcroughanturns out BBC radio actually uses mpeg-dash for everything15:10:09
@n4ch723hr3r:nope.chatn4ch723hr3ryou can probably use the liquidsoap file and mod it from HLS to mpeg15:10:59
@n4ch723hr3r:nope.chatn4ch723hr3rso you should probably read into liquidsoap config/scripting15:11:43
@emilazy:matrix.orgemilychannel topic: "Declaratively manage your switching, routing, wireless, tunneling and more."15:18:00
@emilazy:matrix.orgemilythis is all application layer stuff15:18:32
@toonn:matrix.orgtoonn 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
