INTRODUCTION

Overview

gstreamill is an open source, based on gstreamer-1.0 with dvr support and hls output.

Highlight

  • hls, http progressive streaminig, udp output.
  • Multi-Rate with GOP Alignment.
  • RESTful management interface, allowing easy integration into operator environment.
  • Job is descript in json.
  • Job run in subprocess, and auto restart on error.
  • Base on gstreamer and easy to extend.
  • B/S Management.
  • Time Shift and Catchup.

  • start gstreamill

    service gstreamill start

  • stop gstreamill

    service gstreamill stop

  • invoke a job

default management port is 20118, use curl to invoke test job via management interface for example:

    curl -H "Content-Type: application/json" --data @examples/test.job http://localhost:20118/admin/start
  • invoke a job in foreground, the debug mode:

      gstreamill -j job_descript_file
    
  • access output via http progressive download:

      http://host.name.or.ip:20119/test/encoder/0
    
  • access output use via m3u8:

      http://host.name.or.ip:20119/test/playlist.m3u8 (live)
      http://host.name.or.ip:20119/test/playlist.m3u8?timeshift=3600 (time shift)
      http://host.name.or.ip:20119/test/playlist.m3u8?position=1486556428 (time shift Wed Feb  8 20:20:28 CST 2017)
      http://host.name.or.ip:20119/test/playlist.m3u8?start=201506060606&end=20150606070600 (callback)
    

Management interface

  • start a job over http use curl

      curl -H "Content-Type: application/json" --data @examples/test.job http://localhost:20118/admin/start
    

test.job is job description in json, can be found in examples directory.

  • stop a job

      curl http://host.name.or.ip:20118/admin/stop/job_name
    

job_name is value of the "name" field in job description.

  • query gstreamill stat:

      curl http://host.name.or.ip:20118/stat/gstreamill
      curl http://host.name.or.ip:20118/stat/gstreamill/job/test
    
  • query gstreamer information:

      curl http://host.name.or.ip:20118/stat/gstreamer[/plugin]
    

Output

job name is the value of name of job description.

JOB file structure:

{
    'name' : 'cctv2',
    'debug' : '3',
    'is-live' : false,
    'log-path' : '/home/zhangping/tmp/cctv2',
    'source' : {
        ...
    },
    'encoders' : [
        ...
    ],
    'm3u8streaming' : {
        ...
    },
    "dvr_duration": 86400
}

name : job name

debug : debug option, reference gst-launch gst-debug, optional.

is-live : true for live source, false otherwise, for example transcode, default is true.

log-path : dont log to default log direcotry for non-live source, log to log-path if it is presented.

source : source of encoders.

encoders : encoders.

m3u8streaming : m3u8 streaming

dvr_duration : dvr duration, seconds, it's optional.

structure of source:

"source" : {
    "elements" : {
        ...
    },
    "bins" : [
        ...
    ]
}

structure of elements:

"elements" : {
    "element" : {
        "property" : {
            ...
        },
        "caps" : "..."
    },
    ...
}

structure of bins:

"bins" : [
    bin,
    bin,
    ...
]

bins is an array of bin, syntax of bin is like gst-launch, for example:

[
    "udpsrc ! queue ! tsdemux name=demuxer",
    "demuxer.video ! queue ! mpeg2dec ! queue ! appsink name = video",
    "demuxer.audio ! mpegaudioparse ! queue ! mad ! queue ! appsink name = audio" 
]

in this example, first bin with tsdemux has sometimes pads, second and third bin link with first bin: demuxer.video and demuxer.audio. second bin with appsink named video and third bin with appsink named audio. source bins must have bin with appsink that is corespond endoders' source.

structure of encoders:

"encoders" : [
    encoder,
    ...
]

encoders is an array of encoder, encoder is an object, every encoder correspneds an encode output, that means gstreamill support mutilty bitrate output.

structure of encoder:

{
    "elements" : {
        ...
    },
    "bins" : [
        ...
    ],
    "udpstreaming" : "uri"
}

elements and bins is just the same as source structure in syntax, the differnce is encoder bins must have bins with appsrc element, appsrc must have name property, the value of name is the same as appsink name value in source bins. udpstreaming uri is udp streaming output uri, it's optional.

m3u8streaming is hls output, it's optional:

"m3u8streaming" : {
    "version" : 3,
    "window-size" : 10,
    "segment-duration" : 3.00,
}

There are examples in examples directory of source.
