• TCP connection refused with FFMPEG

  2 février 2017, par Samul

  OFFICIAL EDIT :

  I thank you so much for your help but I am still encountering problems.

  My ffserver.conf file is like this :

  # Port on which the server is listening. You must select a different
  
  # port from your standard HTTP web server if it is running on the same
  
  # computer.
  
  HTTPPort 8090
  
  
  
  # Address on which the server is bound. Only useful if you have
  
  # several network interfaces.
  
  HTTPBindAddress 0.0.0.0
  
  
  
  # Number of simultaneous HTTP connections that can be handled. It has
  
  # to be defined *before* the MaxClients parameter, since it defines the
  
  # MaxClients maximum limit.
  
  MaxHTTPConnections 2000
  
  
  
  # Number of simultaneous requests that can be handled. Since FFServer
  
  # is very fast, it is more likely that you will want to leave this high
  
  # and use MaxBandwidth, below.
  
  MaxClients 1000
  
  
  
  # This the maximum amount of kbit/sec that you are prepared to
  
  # consume when streaming to clients.
  
  MaxBandwidth 1000
  
  
  
  # Access log file (uses standard Apache log file format)
  
  # '-' is the standard output.

  # You must use 'ffmpeg' to send a live feed to ffserver. In this

  # ffserver can also do time shifting. It means that it can stream any
  
  # previously recorded live stream. The request should contain:
  
  # "http://xxxx?date=[YYYY-MM-DDT][[HH:]MM:]SS[.m...]".You must specify
  
  # a path where the feed is stored on disk. You also specify the
  
  # maximum size of the feed, where zero means unlimited. Default:
  
  # File=/tmp/feed_name.ffm FileMaxSize=5M
  
  File /tmp/feed1.ffm
  
  FileMaxSize 200K
  
  
  
  # You could specify
  
  # ReadOnlyFile /saved/specialvideo.ffm
  
  # This marks the file as readonly and it will not be deleted or updated.
  
  
  
  # Specify launch in order to start ffmpeg automatically.
  
  # First ffmpeg must be defined with an appropriate path if needed,
  
  # after that options can follow, but avoid adding the http:// field

  I started my server and executed :

  No error message and everything looks fine.

  After that I execute this (in your answer, I think you forgot the port number) :

  ffmpeg -i "rtsp://200.180.90.95:554/onvif1" -r 25 -s 640x480 -c:v libx264 -flags +global_header -f flv "http://45.79.207.38:8090/feed1.ffm"

• WebM live streaming via DASH

  23 février 2017, par ewack

  I am following the instructions here to try to make WebM live streaming via DASH. My input is from an Axis camera and it is streaming as h264 encoding. I am using node to spin up the ffmpeg processes. I am able to create the .hdr file and the .chk files. The .mpd file is even created but it’s empty and I get an error saying :

  Why is ffmpeg creating an empty .mpd file ?

• ffmpeg image and flask app in two different containers in Docker compose. How do I use ffmpeg in flask app ?

  19 mars 2017, par Conor Quinn

  Here is my docker compose yml file :

  ffmpeg:
  
      image: jrottenberg/ffmpeg:ubuntu
  
      tty: true
  
  flask_app:
  
    build: ./flask_app
  
    #image: conorquinn01/composeapp
  
    command: python ./flask_app/app.py
  
    ports:
  
     - "5000:5000"
  
    volumes:
  
     - .:/muse_compose2
  
    links:
  
      ['ffmpeg']

  Not sure how to do this. Thanks.
