For debugging purpose, WCS includes the utility to capture RTSP stream from file obtained by tcpdump or any other IP packets dump collection tool. Then, the stream is published via RTSP, emulating IP camera. In its turn, WSC can capture RTSP stream from this "camera". The feature is useful when RTSP-source itself is not accessible, but there are dump files of stream from that source. The utility works with RTSP iterleaved session files only.
To launch utility the following parameters mus be set:
- a directory containing dump files on server
- a port to listen RTSP incoming connections
Launch example:
java -Dcom.flashphoner.fms.AppHome=/usr/local/FlashphonerWebCallServer -cp /usr/local/FlashphonerWebCallServer/lib/tbs-flashphoner.jar:/usr/local/FlashphonerWebCallServer/lib/* com.flashphoner.tools.rtsp.RtspPcapServer /usr/local/FlashphonerWebCallServer/pcaps 554
Where
/usr/local/FlashphonerWebCallServer/pcaps - directory on server
554 - port number (RTSP standard)
If WCS is launched on this server, the utility port number should be out of ranges used by WCS.
The utility prints all information to stdout. Foe example, if there is one file log.pcap in /usr/local/FlashphonerWebCallServer/pcaps directory, the following will be prited to console:
04:35:20,721 INFO RtspPcapServer - Starting
04:35:22,244 INFO RtspPcapServer - Available sources:
04:35:22,245 INFO RtspPcapServer - Source{path=/usr/local/FlashphonerWebCallServer/pcaps/log.pcap, pcap=io.pkts.Pcap@5a39699c, stream=RTSPStream{config=8, data=22052, streamName='live1.sdp'}}
04:35:22,245 INFO RtspPcapServer - Starting PCAP RTSP server
04:35:22,407 INFO RtspPcapServer - Listening PCAP RTSP on address /0.0.0.0 port 554
In this case, stream can be captured from address
rtsp://hostname/live.sdp
where hostname is server name with utility running.
If the directory contains a number of dump files, the stream names should not be the same, only one of such streams will be captured.
