my reference: now i see https://docs.flashphoner.com/display/WCS5EN/Using REST hook to authorize user by domain
1. How to correctly set rest-hook?
2. how to check rest-hooks is work?
3. how to protect myserver for
ffmpeg push streaming by allow domain
reject via auto publish streaming

my restapi `https://localhost/rest-hooks/connect`
must be response 403
now, i try post `http://ip:8081/apps/EchoApp/connect`, no parameter
alway response status 200

Hello.

now, i try post `http://ip:8081/apps/EchoApp/connect`, no parameter
alway response status 200

On 8081 TCP port, the build-in backend listens for REST hooks. This backend always responds 200 OK on every request.
You should do the following:
1. Install web server
2. Install PHP
3. Implement your own backend script as described here.
4. Update WCS server application defaultApp as described here (step 4).

3. i have own backend script
4.
- try post `http://yourhost/rest-hooks/connect`, it is ok
- use `update app defaultApp -l http://yourhost/rest-hooks`, but not working
how to detect `update app defaultApp -l http://yourhost/rest-hooks` is working ?

Make http traffic dump

Code:

tcpdump port 80 -i any -w log.pcap

In the dump you should see http traffic.
Example:

run <code>update app defaultApp -l "http://localhost/rest-hooks"</code>
show apps always display defaultApp url :http://localhost:8081/apps/EchoApp

client play video stream is OK, but defaultApp not use http://localhost/rest-hooks

Max · Mar 6, 2019

Hello.
Please run this command as

Code:

update app -l "http://localhost/rest-hooks" defaultApp

App key should be last field in command line.

linelin · Mar 7, 2019

%show apps
now i can not see the defaultApp
try run `add app defaultApp defaultApp http://localhost:8081/apps/EchoApp`
return ` App defaultApp already has app key "defaultApp"`
1. how can i do add defaultApp
2. run`update app -l "http://localhost/rest-hooks" defaultApp`, always not working
3. i had push streams to wcs, but can not see the stream in rest api `http://192.168.62.52:8081/app/EchoApp/streams/find_all`

Max · Mar 7, 2019

Hello.

try run `add app defaultApp defaultApp http://localhost:8081/apps/EchoApp`

You cannot add the application with existing key.
On screenshot you've attached there is an application 'defaultApp' with URL http://localhost/rest-hooks on first string. So it should work.
Please collect publishing or playing logs and server configs as described here and send to support@flashphoner.com, we will check.

üse`rest-api/rest-api/pull/rtmp/pull`pull rtmp streaming,
1. can i custom stream name?
2. why Pull rtmp stream is always interrupted after one minute?
see the attach file, log.jpg, flashphoner.txt
thanks

Max · Mar 7, 2019

It seems your pulled stream has empty audio track.
If so try to add setting:

Code:

rtp_activity_detecting=false

to prevent stopping by timeout

Max · Mar 7, 2019

can i custom stream name?

You can't set custom stream name for pulled streams
rest-api/rest-api/pull/rtmp/pull
However you can re-publish pulled stream with a new name
https://docs.flashphoner.com/display/WCS52EN/To+another+RTMP+server
1. Add in flashphoner.properties

Code:

rtmp_transponder_full_url=true

2. Do /pull/push

Code:

{
"streamName": "rtmp://localhost:1935/live/stream1",
"rtmpUrl": "rtmp://localhost:1935/live/stream2",
"options": {}
}

Here stream1 is your pulled stream.
steram2 is your re-published stream.

setting sucess can be play streaming
but too much log
1. how can i do prevent this?
2. what is mean `Codec not found; pt - 119; current pt - 95`? and how to fix it?

Hello

what is mean `Codec not found; pt - 119; current pt - 95`? and how to fix it?

This means your H264 stream goes with payload type (pt) 119, but RTMP pull agent payload type for H264 is 95 by default.
To fix it create file rtmp_agent.sdp with the following content

Code:

v=0
o=- 1988962254 1988962254 IN IP4 0.0.0.0
c=IN IP4 0.0.0.0
t=0 0
a=sdplang:en
m=video 0 RTP/AVP 119 95
a=rtpmap:95 H264/90000
a=fmtp:95 profile-level-id=42e01f;packetization-mode=1
a=rtpmap:119 H264/90000
a=fmtp:119 profile-level-id=42e01f;packetization-mode=1
a=recvonly
m=audio 0 RTP/AVP 103 96 97 98 99 100 102 108 104
a=rtpmap:108 mpeg4-generic/48000/1
a=rtpmap:96 mpeg4-generic/8000/1
a=rtpmap:97 mpeg4-generic/11025/1
a=rtpmap:98 mpeg4-generic/12000/1
a=rtpmap:99 mpeg4-generic/16000/1
a=rtpmap:100 mpeg4-generic/22050/1
a=rtpmap:104 mpeg4-generic/24000/1
a=rtpmap:102 mpeg4-generic/32000/1
a=rtpmap:103 mpeg4-generic/44100/1
a=recvonly

and place this file to WCS_HOME/conf, then restart server.

i often recive following message, and video quality may be change to lower video resolution

Code:

Not enough bandwidth, consider using lower video resolution or bitrate. Bandwidth 0 bitrate 51

- It is mean Bandwidth vary lower, video bitrate too big ?
- How to fix this problem?

Max · Mar 14, 2019

Hello.
Please check the channel bandwidth between publisher and server, between server and player as described here. The channel test result will show you the maximum bitrate value, so you should limit the publisher video bitrate with this value. For example if iperf shows 1,15 mbit/s bandwidth, you should limit the maximum publisher bitrate with 1 mbit/s. Bitrate management in WCS is described here in details.

how to setting publish video timeout, when nobody play this streaming?

flashphoner.property
cdn_outbound_connection_timeout right?

Max · Mar 29, 2019

Hello.
The option

Code:

cdn_outbound_connection_timeout

is intended to use with CDN only.
If you want to stop publishing a stream that have no subscribers in certain time, there's no explicit config option for this. You can do it using REST API:
1. Send the query periodically

Code:

/rest-api/stream/find
{
    "name": "your_stream_name",
    "published": "false"
}

It returns a list of subscribers sessions or 404 Not found
2. If 404 Not found is received in certain time, stop publishing the stream

linelin · Apr 1, 2019

hi Max,
my step
- client play `rtmp://aa.bb/live/stream`
- wcs start pull `rtmp://aa.bb/live/stream` video
- run `/rest-api/stream/find_all`, return one stream publish
- client close video
- After one minute, run `/rest-api/stream/find_all`, return NOT FOUND video
how to setting publish timeout, let timeout extend to 30 minutes ?

Max · Apr 2, 2019

Hello.
You can set the following parameter to desired timeout in milliseconds

Code:

rtmp_activity_timer_timeout=1800000

In this case, RTMP pulled stream with no subscribers will be terminated in 30 minutes.
By default, this interval is set to 60000 ms, or 1 minute.
