abr-broadcaster's Introduction

Adaptive Bitrate Broadcaster

Adaptive Bitrate Broadcaster provides a simple interface for live encoders of audio and video streams for adaptive bitrate streaming over HTTP. It supports two most popular Adaptive Bitrate(ABR) protocols namely HLS and DASH. It provides two method of interfaces.

HTTP-based REST API interface.
Web based GUI

Installation

See INSTALL.md for installation instructions

Usage

The broadcaster can be used either with Web GUI interface or with REST API interface. They listen on port 8888.

Web GUI

Open the Virtual Host URL http://ip_address:8888 in your Browser. For example go to http://127.0.0.1:8888, when opening the browser from the same machine as ABR Broadcaster. Otherwise replace 127.0.0.1 with the IP address of the ABR Broadcaster. The usage of the webpage should be simple and self explanatory.

REST API interface

Refer to the API documentation for details and examples of REST API based usage.

Known Issues

Video codec h264_videotoolbox does not work resolutions 240p and below.

dash multi variants not working

works well for hls. but not working on dash. Only showing 720x1280 as available bitrate

Encoder instance not starting

Please help me out,

MPEGTS UDP Support

Hi,

Hope you are doing well and keeping safe.

Is there any way to get MPEGTS output.

ffmpeg dash identifiers fail

Hello @jkarthic-akamai ,

first of all, very nice project!
I did something like this but without multiple bitrates so far, so I just jumped on yours. ;-)

HLS works perfect
but
DASH always fails on my end, because of
Could not write header for output file #0 (incorrect codec parameters ?): No such file or directory

I am using ffmpeg 4.1

I stripped the commend totally to [f=dash] and it worked fine.
So I put the params back again except media_seg_name=and it worked fine as well!

At the end it seems like this part
media_seg_name='162849/chunk-stream_\\$RepresentationID\\$-\\$Number%05d\\$.\\$ext\\$':init_seg_name='162849/init-stream\\$RepresentationID\\$.\\$ext\\$'

Next I looked as at the ffmpeg dash documentation again.
ffmpeg->dash

What I couldn't see in the identifiers

Available identifiers are "$RepresentationID$", "$Number$", "$Bandwidth$" and "$Time$".

I am no ffmpeg pro but what I can't see is the $ext identifier.

Why did you use those additional identifiers if I may ask?

Any idea why it might fail there?

Encoder stops after an interval

The encoder stops after some point and resumes automatically. E.g. It stops at chunk 100, resumes at 130, then again stops at 230, resumes at 260 and so on.

How to resolve this?

Encoder is not starting

i m using decklink recorder as input,

after configuring hls output encoder not starting, where am i doing wrong

wsgi:error

Hi, I'm having an issue with this project that just happened today. Yesterday it ran fine so I'm not sure what's up. I'm getting wsgi:error constantly when trying to add inputs/outputs and nothing is streaming. Here is an example (with ip addresses and host names edited out):
[Thu Jul 04 01:29:03.657654 2019] [wsgi:error] [pid 4245:tid 139764174927616] [client ...:15844] INSERT INTO CapInputNames ( InputInterface, InputId, InputUrl ) VALUES( "URL", "0", "rtmp://127.0.0.1/live" ) , referer: http://********.com:8888/

Thank you!
