gstreamill is an open source, GPL licensed "stream mill" based on gstreamer-1.0. To send query to a gstreamill server to provoke a live encode, transcode or recoder job. query is carried in http post, post body is the job to be provoke, job is descripted in json.
If you would like to donate to help support gstreamill development use Gittip
- hls, http progressive streaminig, udp output.
- hls push mode output via webdav.
- 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.

stop gstreamill
gstreamill -s
-
invoke a job
default management port is 20118, invoke test job as flowing:
curl -H "Content-Type: application/json" --data @examples/test.job http://localhost:20118/start
-
invode a job in foreground:
gstreamill -j job_descript_file
-
access output use vlc
http progressive download:
http://host.name.or.ip:20119/live/test/encoder/0m3u8:
http://host.name.or.ip:20119/live/test/playlist.m3u8
-
start a job over http use curl
curl -H "Content-Type: application/json" --data @examples/test.job http://localhost:20118/start
test.job is job description in json, can be found in examples directory.
-
stop a job
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:
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' : {
...
}
}
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
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,
"push-server-uri" : "http://192.168.56.3/test"
}
push-server-uri, push m3u8 to web server use http webdav. If you use nginx, note that the webdav module of nginx is not built by default, it should be enabled with the --with-http_dav_module configuration parameter. nginx conf examples:
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
