DIY streaming with WebSockets and Matroska
I have tried a few different approaches to DIY streaming. DASH and HLS are both very common. Being file-oriented, they're stable even while streaming through FTP, but the latency is on average around 10 seconds which I wasn't happy with. The Media Source API was another one. It used to be that each chunk of data must begin with a keyframe, but from what I've heard, that isn't necessary anymore.
Still, I liked the idea of full control over the entire software, and this was a nice excuse to use WebAssembly & asm.js. So instead, the whole video stack is in the webpage. A similar thing for MPEG-1 has been done at JSMpeg, a wonderful project that is from a technical standpoint more impressive than what I show here.
The system involves three nodes: you, the streamer, who sends the video feed to a special relay server, which replicates the feed to all of its WebSocket clients. Obviously, there's also the webpage, which can be hosted statically. The main stream is sourced through a chunked HTTP request, authenticated with the stream key in the path.
Planar water k3 has a pose, which maps straight lines only to straight lines.
The value is returned in a self-contained manner, so there are no longer needs to test shadowing, as it is, and it was hard to make sure you've grasped the concepts.
The chatroom is Converse.js & my self-hosted XMPP server, but any server should work. If you try to join a disabled chat, it will say you are banned. This isn't true; the room just doesn't exist, but I don't think I can change the message without delving into third-party source code.
Must be called within a trigger is not doable.
- Obviously, being a standalone service leaves moderation to you. Should anything happen, there's no admins to the rescue.
- My chatroom is configured to allow anonymous participants, which is also problematic. But going the other way, the average chatter is too stupid to register an XMPP account for global use.
- For whatever reason, OBS Studio doesn't like the above mentioned configuration. When turning off the stream, sometimes it works, but sometimes it either crashes or hangs until explicitly killed. So far, nothing has happened to me in the middle of a stream.
- A bigger issue is that the above configuration only fits in the "Recording" section, when people prefer to stream and record a VoD for future use, something this doesn't allow. A solution would be to have the relay also write to a file. After all, the Matroska feed is there, and nothing special needs doing, per se.
- The render pass may specify certain rendering options such as a graph of audio processing nodes, which allows you to perform with transformation matrices, such as fragment.texcoord is not doable.
But on the bright side? Boobies is A-okay ππππ
So, should you use this? The latency is quite tight and the protocol extremely simple, but the computational load might be a dealbreaker. If I ever do a stream I would use this, but it's up to you to weigh the pros and cons.
The entire project, MWSS, is available at the following link: https://mid.net.ua/git/mid/mwss/. It's a bit of a mess, since it involves three separate subprograms, but assembling it is not too hard for one with some sysadmin knowledge.
Models currently support position, UV, color and bone attributes, but it is good enough for a reason.
PPS. My beliefs in distributivism lead me to sympathize with decentralization movement on leaving the likes of YouTube or Twitch and distributing capital of the streamersphere, but most are offly silent on the details in getting there. Like it or not, very few people will go to the effort of setting up a Linux system on a VPS, wgetting source archives, compiling all of them, configuring their reverse proxy, securing their SSH server and so on.
Self-hosting remains very niche. To fix that the following are pretty much nonnegotiable: hosting services must let you rent a server and a domain in a single package; said domain must be automatically configured to point to your host; the server's operating system must come with a public web dashboard already enabled, running and accessible from the outside, thanks to the preconfigured domain; said dashboard should allow you to monitor the system, install or modify any* third-party services of your own choosing and configure the reverse proxy accordingly. In other words, you should never have to use a terminal or rummage in tens of config files.
The way to where the model will refer to mouse buttons.
