Make PC a streaming server
How can I setup my pc to stream media files anywhere?
Also I'd like to ssh into my computer and be able to access youtube-dl to download m4a audio files from youtube.
How do I setup ssh?
Use 'ssh -X'. It can be too slow though.
can you stream content with owncloud?
VLC is a solution: https://wiki.videolan.org/Documentation:Streaming_HowTo/
It's a bit experimental, but you could try WebTorrent.io. There is a demo sites as BitChute.com that shows what it can do.
