• FFServer streaming H.264 from Logitech C920

  23 octobre 2014, par Ricardo Frederico Leote Mota

  I’m having some trouble trying to implement a web live stream from my Logitech C920 webcam w/ H.264 encoding using ffmpeg/ffserver.

  Here is the configuration file I’m using for the ffserver :

  # 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.
  
  Port 8090
  
  
  
  # Address on which the server is bound. Only useful if you have
  
  # several network interfaces.
  
  BindAddress 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.
  
  CustomLog -
  
  
  
  ##################################################################
  
  # Definition of the live feeds. Each live feed contains one video
  
  # and/or audio sequence coming from an ffmpeg encoder or another
  
  # ffserver. This sequence may be encoded simultaneously with several
  
  # codecs at several resolutions.
  
  
  
  <feed>
  
  
  
  # You must use 'ffmpeg' to send a live feed to ffserver. In this
  
  # example, you can type:
  
  #
  
  
  
  File /tmp/feed.ffm
  
  FileMaxSize 100M
  
  
  
  # You could specify
  
  # ReadOnlyFile /saved/specialvideo.ffm
  
  # This marks the file as readonly and it will not be deleted or updated.
  
  
  
  # Only allow connections from localhost to the feed.
  
  ACL allow 127.0.0.1
  
  
  
  </feed>
  
  
  
  
  
  ##################################################################
  
  # Now you can define each stream which will be generated from the
  
  # original audio and video stream. Each format has a filename (here
  
  # 'test1.mpg'). FFServer will send this stream when answering a
  
  # request containing this filename.
  
  
  
  <stream>
  
  
  
  Feed feed.ffm
  
  Format mp4
  
  
  
  # Audio settings
  
  NoAudio
  
  
  
  # Video Settings
  
  #VideoSize 1280x720                      # Video resolution
  
  #VideoFrameRate 30                      # Video FPS
  
  #AVOptionVideo flags +global_header          # Parameters passed to encoder
  
  #AVOptionVideo cpu-used 0
  
  #AVOptionVideo qmin 10
  
  #AVOptionVideo qmax 42
  
  #AVOptionVideo quality good
  
  PreRoll 0
  
  StartSendOnKey
  
  #VideoBitRate 400                      # Video bitrate
  
  
  
  </stream>
  
  
  
  # Server status
  
  
  
  <stream>
  
  Format status
  
  
  
  # Only allow local people to get the status
  
  ACL allow localhost
  
  ACL allow 192.168.0.0 192.168.255.255
  
  
  
  </stream>
  
  
  
  
  
  # Redirect index.html to the appropriate site

  And here is the command I’m issuing through the command line and the respective output :

  ffmpeg -s 1280x720 -f video4linux2 -r 30 -vcodec h264 -re -i /dev/video0 -copyinkf -codec copy h**p://localhost:8090/feed.ffm

  [00007f5234003948] core stream error : cannot pre fill buffer

  And I can’t watch the stream on the web browser side also.

  Could someone give me an hint on this ?

  Many thanks and your help is much appreciated ! ;)

• Powerful Video Analytics and Audio Analytics for Piwik

  This article is a showcase of the new powerful video and audio analytics product built for Piwik.

  Why media analytics ?

  We all love media content such as videos as they can make our experiences on websites and apps so much more interesting. A growing number of websites now utilize media files in one form or another : a video presentation of a product or service, a video tutorial teaching you how to do something or interviews with key speakers. Also many creators and distributors are publishing audio files such as podcasts or music songs, and even broadcasting live video events such as music concerts or an entire conference online.

  Whenever you publish videos or audio media on your websites or applications, Media Analytics provides you with clear insights on how your audience interacts with your content. It helps you see what content works and why – so you can better understand and further grow your business !

  

  Valuable insights in Real time

  

  See where your audience comes from.

  How will Media Analytics help me grow ?

  • Better understand your audience : who are the users playing videos and for how long, how often, and where have they dropped off.
  • Gain quick insights into how interaction with your media changes over time with easy to use graphs and report overviews.
  • Get closer to your users by seeing every action of your visitors before and after they utilized your media.
  • View valuable insights in Real time : ‘most popular content right now’, your real time audience map, and more.
  • See where your audience comes from. Drill down right from continents to specifics such as cities.
  • Share and export media analytics reports with your colleagues by creating custom email reports.
  • Video and audio players are supported either automatically (for Youtube, Vimeo, HTML5…) or via a simple custom player integration.
  • No data limit and 100% privacy and data ownership.

  Best of all, it is easy to use and understand, and integrates perfectly with Piwik. Media Analytics complements other reports to give you a 360 degree view of how your users engage with your content.
