• Getting troubles when I generate rtsp stream as an output with ffmpeg from static images as an input

  10 août 2013, par Ilya Yevlampiev

  I'm trying to start the rtsp stream via feeding ffmpeg with static images and feeding ffserver with ffmpeg output.

  The first problem appears from the ffserver.config :

  Port 12345
  
  RTSPPort 8544
  
  BindAddress 0.0.0.0
  
  MaxHTTPConnections 2000
  
  MaxClients 1000
  
  MaxBandwidth 1000
  
  CustomLog /var/log/ffserver-access.log
  
    <feed>
  
  File /tmp/videofeed.ffm
  
  FileMaxSize 3M
  
  #Launch ffmpeg -s 640x480 -f video4linux2 -i /dev/video0
  
  #Launch ffmpeg http://localhost:8090/videofeed.ffm
  
  Launch ffmpeg -loop 1 -f image2 -r 20 -b 9600 -i Janalif.jpg -t 30 http://127.0.0.1:8090/videofeed.ffm -report
  
  ACL allow 127.0.0.1
  
    </feed>
  
    <stream>
  
  Format rtsp
  
  #rtsp://localhost:5454/test1-rtsp.mpg
  
  Feed videofeed.ffm
  
  #webcam.ffm
  
  Format flv
  
  VideoCodec flv
  
  VideoFrameRate 30
  
  VideoBufferSize 80000
  
  VideoBitRate 200
  
  VideoQMin 1
  
  VideoQMax 5
  
  VideoSize 640x480
  
  PreRoll 1
  
  NoAudio
  
    </stream>
  
    <stream>
  
  Format status
  
    </stream>

  Please ignore codecs etc in stream part. The problem appears for RTSPPort, after starting the server nmap shows no binding to 8544, only 12345 port is used.

  8090/tcp  open  unknown
  
  12345/tcp open  netbus

  I can download mpeg stream through http from http://localhost:12345/test1-rtsp.mpg. How can I setup 8544 port working ?

  and another question is about Launch part of the stream. Am I right, that ffserver executes the content of Launch line ? If so, how can i configure ffserver to wait the stream in some particular port, but start streaming at the moment I desire ?

  P.S. The solution looks like Säkkijärven polkka, hoowever the idea behind this construct is to provide the controlled rtsp stream to emulate the camera output. In future I plan to substitute the command line for ffmpeg with some java bindings for it to produce the program-controlled images to the camera input to test the computer vision, that's why I need a way to launch ffmpeg independently on ffserver.
