Live Stream APIs/Solutions - api

Twitch has this feature on their video player where you can create short clips of someone's stream. Does anyone know if there are any Live Streaming APIs that have this functionality? I want to build a twitch clone of some sort with the ability to clip mid-stream.

What you looking for is insertable streams api. It allows you to access the media stream and apply transformations to the stream.
Check out this example which applies low pass filter on the audio track. There's a link to code at the bottom of the page.

video live streaming application in React Native

I am trying to implement video live streaming
live streaming and
upload it to server and
save the streaming video (Playback)
in react native can any one help me with a sample project
this is will be helpful https://www.npmjs.com/package/react-native-video
for point upload it to server, what exactly do u need upload? video uploading or something else?
So - you'll need a backend server that can accept a video stream, and convert it into a stream that can be consumed in React Native. You'd also like the server to save the streamed video, and encode it so it can be played back as video on demand (VOD) after the stream has stopped. None of this is React - it'll all be done on the backend.
You can build all this yourself, but there are a number of APIs that can do this for you. Disclaimer: I work for one such company: api.video. (A Google search will find others)
For livestreaming from the browser, you can use getUserMedia and stream to a server. (you can see my demo using JavaScript at livestream.a.video. This stream wil be visible to all your users, and then also recorded and saved as VOD for later playback.
To upload a recorded video - you can use file.slice() to break the video into manageable chunks, and upload to the server - for transcoding into a video stream (demo at upload.a.video, and tutorial.)
For playback, these APIs will give you a player URL or the m3u8 url that you can incorporate into a video player. This is your React Native part - and there are several video players that you can add into your application to playback HLS video. At api.video, we have our own player, and also support 3rd party players.

Is it possible to play Youtube stream as sound in Flutter?

For example, if I want to stream a live video from Youtube as a stream in audio player, can I do it in Flutter? I can't seem to figure out how to get a direct link to the sound, so I don't know if it is possible. If not, do you guys have any alternatives?
At the moment I am using Audioplayers library, but if it can't support streaming, any suggestions how to do this?

Can you obtain audio stream data to the System output device using CoreAudio?

Is it possible to obtain a stream of audio data arriving at the system output (speakers, headphones, etc.) using CoreAudio or another framework?
Example: You're listening to a song on iTunes while watching a YouTube video, all while playing a computer game that makes sounds of its own, all of which are being played through your computer's speakers (Probably terribly annoying). My app would need to receive the entire mix as streaming data.
Thanks in advance.
Not at a user application's Core Audio or other app framework level. Some audio output capture/snoop apps may do this with a kernel extension (kext), or perhaps a replacement audio hardware driver.

Streaming music on your website through custom player / application (iTunes)

I was doing some research to find out ways that would allow me to stream music on my website legally. I came across iTunes partner program which allows to stream music on a website through their embedded players. I was wondering is it possible to stream iTunes music through your own custom player? If that is not possible via iTunes, then what other methods are available?
You could do this with a server software like Icecast, there is some good tutorials on setting this up here: http://www.icecast.org/docs.php
Depending on how many browsers you want to support you might want to setup two streams, one in MP3/OGG and a "backup" stream in Flash. Then add some detection as to what the browser supports and present the correct stream (i.e.: Use the HTML5 <audio> tag for playing MP3/OGG to browsers that support this, and use your flash stream for the rest)
their program allowing playback of music in the iTunes Store is likely only for those with the intention to sell music, without providing a commerce business, you'd be breaking their partner program T&C's.
