kandi X-RAY | restream Summary
Convert REST APIs to subscribable streams. I do quite a bit of work visualizing streaming data, and I have been continually frustrated with the difficulty of finding public streams to work with. First of all, there are very few public streams to work with. Even twitter, the most prominent of public real-time data sources, makes it hard to use their streaming API for anything beyond purely personal use. That said, there are a number of more-or-less public REST APIs that provide time-sensitive data - the NYT top story API, for example, and various financial data services. It would be great to have generic tooling to convert these polling-based interfaces into push services.

QUESTION
I am streaming video from an IP camera to Youtube using the restreamer software (https://datarhei.github.io/restreamer/) running on a Raspberry Pi 4.
Actually everything works as well. But when the stream is interrupted (for whatever reason), a new livestream is created only when I click on the "Dismiss" button in Youtube Studio.
But since I want to start the new stream automatically, I'm looking for a way to execute the click on the button (or the associated command) via the Youtube API. How can I execute this?

Answered 2021-Feb-17 at 12:58I will answer my own question because I found the problem description and a solution in another forum: https://obsproject.com/forum/threads/stream-didnt-show-error-or-load-to-youtube.130897/
Something has changed on youtube in the last few days, but the solution to manage a real streaming reconnection is this: from the youtube control room from the manage icon, you need to create a scheduled streaming. Start the encode on this stream and everything will work fine. If the connection drops, youtube will say streaming offline; when the connection is re-established, streaming restarts.
QUESTION
Is there some formula like frames per second X resolution to determine the bitsPerSecond? I can't understand what values I'm supposed to be using. I want to specify the bitsPerSecond for 720p, 1080p and 4k video. I'm not sure if file type matters but this will most likely befor webm or mp4. I'm afraid some of my files are unnecessarily large while others I'm not using enough bits causing video glitches.
I did find values listed here.... https://restream.io/blog/what-is-a-good-upload-speed-for-streaming/ But even that im not sure how to convert over.
I am using RecordRTC https://github.com/muaz-khan/RecordRTC which is a wrapper for the MediaRecorder.

QUESTION
I am pretty new to Dart, and still wrapping my head around streams. Specifically I am having some difficulty with finding the proper way of making a function that takes a window of N elements from a stream, applies a function to it and restreams the results.
To clarify what I mean, I include an example that I implemented myself which led me to this question. The code takes a byte stream from a file and converts 4 byte chunks to an integer stream. By using an await for
I was able to accomplish what I wanted but I am looking for a more idiomatic stream based function that accomplishes the same thing, more succinctly.

QUESTION
Before requesting audio data AVPlayer requests byte range 0-1 from FFMPEG.
FFMPEG gives a 200 response, but AVPlayer requires a 206 response.
This results in the request failing and audio can't be played.
Expected behavior: Play tracks when streaming through ffmpeg
Current behavior: When trying to stream with ffmpeg we get "Operation Stopped"
Sample FFMPEG command:

Answered 2021-Jan-18 at 17:40I asked this question on the ffmpeg email list and it seems it's not possible:
If I understand your request correctly, you are not asking for a change of a return type (you could probably do that yourself) but for the implementation of byte range requests. I don't think this is possible at all with FFmpeg.
Also it's not possible to get AVPlayer to ignore the byte range request:
it is an apple standard that media providers need to support http 1.1 with the range header (check out the iTunes store guidelines for podcasts for example), so I wouldn't expect it anytime soon
SO Q'n: Is there a way to stop the avplayer sending a range http header field

QUESTION
I just want to know how to read or get data from an MP3 stream (URL), and then restream it in Flask.
I already have a Icecast2/DarkIce service running an MP3.
The purpose of this is that I want to re-stream that mp3 using my own Flask code, so this stream together with all my services are running on the same Flask server.
Thanks so much in advance!

hi i am restreaming an hls stream as a hls stream
...ANSWER
Answered 2019-Feb-18 at 02:02By default, FFmpeg will try to reencode the input, even if you don't use any encoding related parameters.
If you want to just copy the stream as is, you should try the streamcopy function:
QUESTION
I made a test test bot for discord.js using Node.js / ffmpeg, to play a radio station in a channel on discord and there are no problems there, however i was thinking about how it would stream the same station to multiple servers/channels efficiently.
For example, if I am playing it on "Discord server one":
...ANSWER
Answered 2020-Jan-30 at 19:38Since the stream is managed by Discord.js (you only give a link, and Discord.js uses FFMPEG to handle it), you can't do it without modifying the Discord.js code.
Your question is relevant but I don't think it's feasible, at least if you uses Discord.js. You can still open an issue on their Github repository to ask them.

I have a microservice that proxies every request adding one more field to it. With normal requests it's very easy, just add the field in the request.body and properly set the headers but for multipart/form-data requests I'm in trouble since days because if I add a field in the request.body, it will disappear.

Install restream
You can use restream like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
