Please help with above queries

Thank you

Good day.

1. What are the formats(RTSP, rtmp, hls, mp4..... ) supported by Flashphoner to stream on Chrome browser

You can capture RTSP or RTMP stream from NVR or IP camera by URL rtsp://nvr:554/stream or rtmp://nvr:1935/live/stream. The codecs supported are H264 or VP8 for video and AAC, G.711 or Speex for audio. Please read details about RTSP capturing here and about RTMP pulling here
Then, stream captured may be played as WebRTC, RTMP, RTSP, HLS

2. Does this supports other features like playing recorded video from NVR , PTZ operations .

You can play VOD from recording file as described here. The file must be H264 + AAC in MP4 container and must be placed to the folder defined by the following WCS parameter

media_dir=/usr/local/FlashphonerWebCallServer/media

WCS does not modify a video recorded by any way, just play it as is.

That means we need keep the media file in specified path there, then stream will get created with flashphoner to use on browser?

But we want know that is there any way to get video for specified time from NVR server and managed to play on Browser?

Yes. To play a video within a specified time range you should:
1. Capture a stream from NVR to WCS by URL rtsp://nvr:554/stream or rtmp://nvr:1935/live/stream
2. Record the stream published
3. Play the recording file from WCS by URL https://wcs:8444/client/records/stream.mp4?start=11&end=60 with begin and end timestamps in seconds

But we want know that is there any way to get video for specified time from NVR server and managed to play on Browser?

If video recordings are already stored on NVR server, you can either translate them as described above or copy them to the records folder on WCS by SSH or SCP to play them as described at p. 3 above.

Once we published the stream from NVR to WCS, it getting automatically closed or disconnected after few seconds or 1-2 mins . and also not getting recorder clips for that duration.

Can you please help us in this issue . as of now we are demo licence.

Once we published the stream from NVR to WCS, it getting automatically closed or disconnected after few seconds or 1-2 mins . and also not getting recorder clips for that duration.

Please clarify how do you publish a stream:
- capture from NVR by RTSP URL rtsp://nvr:554/stream
- capture from NVR by RTMP URL rtmp://nvr:1935/live/stream
- publish RTMP from NVR to WCS rtmp://wcs:1935/live/stream
Also please collect a report including client debug logs as described here and send using this form.
Or you can provide SSH access to your server and URL to capture from NVR using this form.

Using RTSP URL from NVR

Using RTSP URL from NVR

Please provide SSH access to your server and RTSP URL to capture from NVR using this form, we will check

 

[revanreddy]

For that we need to admin permission in our end. is there any other way to cross check the issue.

Note: I tried with rest client for above scenarios

We need at least RTSP URL, to check its playback in our test environment.

 

[revanreddy]

Actually Our RTSP URL works only in our local environment .. it won't work for you

 

[Max]

Try to gather pcap dumps

1. VLC player.

Run wireshark and Start Capture before playback.
As a result you have wireshark.pcap

2. On WCS server.

Launch tcpdump before playback then press CTRL+C to stop capture after test.

sudo tcpdump -i any -s 0 -B 10240 -w log.pcap

As a result you have log.pcap file.

Open these two files in Wireshark to be sure these files contain RTSP packets.

RTSP / RTP - Web Call Server 5.2 - EN - Flashphoner Documentation

docs.flashphoner.com

If you captured RTSP packets properly, please send us these two files using private form or share right here.
Then we will be able to check difference between VLC and WCS or reconstruct stream by provided dumps.

 

[revanreddy]

for your better understanding ...

Actually we are publishing the live stream from Camera to WCS server and trying to get the recording from the time of published.

Is it correct way to get the playback ?

 

[Max]

Is it correct way to get the playback ?

Yes, this is a correct way.
But we need either RTSP link to test, or pcap dump (which must be started to capture before starting RTSP playback), or SSH access to your WCS server and RTSP stream internal address to check the stream playback. You can provide the requires stuff using this form.

 

[Max]

Unfortunately, you've provided only a local addresses both for RTSP camera and WCS server.
We need 24/7 SSH access to the WCS server with sudo privilegies from outside network. Please provide it using this form.

 

[revanreddy]

I have shared pcap dump too as mentioned in previous reply, can you please check that ...

Unfortunately, you've provided only a local addresses both for RTSP camera and WCS server.

Since we don't have public access to our servers , you can not access at this moment

 

[Max]

I have shared pcap dump too as mentioned in previous reply, can you please check that ...

Unfortunately we cannot extract RTSP stream from your dump.
So please collect the dump again on WCS server (start the dump collection before starting RTSP playback), enable client debug logging and collect the report as described here, then send both pcap dump and logs archive using this form.

 

[revanreddy]

What could be the issue for not capturing RTSP stream on WCS Server.

 

[Max]

What could be the issue for not capturing RTSP stream on WCS Server.

Please see the possible known issues list here
Also, RTSP stream can be encoded in AnnexB format, see here.

 

[Max]

The server log fragments you've sent contain no useful information to resolve the issue.
So please either provide SSH access to your server using this form or collect the full report as follows:
1. Enable debug logging by adding to the /usr/local/FlashphonerWebCallServer/conf/flashphoner.properties settings file

client_log_level=DEBUG

2. Restart WCS with the command

sudo systemctl restart webcallserver

3. Start traffic dump collection on RTSP stream port

sudo tcpdump -i any -s 0 -B 10240 -w rtsp.pcap tcp port 654

4. Open RTSP link in Player example or in Media Devices example (Player section)
5. If stream is not playing, wait a minute
6. Click "Stop" in player
7. Stop traffic dump collection
8. Go to tools folder and prepare a report archive

cd /usr/local/FlashphonerWebCallServer/tools
sudo ./report.sh --sysinfo --conf --tar

9. Get the report archive in /usr/local/FlashphonerWebCallServer/reports folder
10. Send the report archive and traffic dump using this form
