  • How to make ffserver which can make a snapshots ?

    4 mai 2016, par Serge Roussak

    I need some solution to take a "good" (not corrupted) snapshots from a camera device.

    Now I try to do this using the ffserver. Here is my config :

    HTTPPort 8090
    
HTTPBindAddress 0.0.0.0
    
MaxHTTPConnections 20
    
MaxClients 10
    
MaxBandwidth 10000
    

    
<feed>
    
  File /tmp/feed.ffm
    
  FileMaxSize 200k
    

    
  ACL allow 127.0.0.1
    
</feed>
    

    
<stream>
    
  Feed feed.ffm
    
  Format jpeg
    

    
  VideoSize 800x600
    
  VideoFrameRate 30
    
  Preroll 5
    
  Strict -1
    

    
  NoAudio
    
  NoDefaults
    
</stream>

    I run ffmpeg as follows :

    ffmpeg -f video4linux2 -i /dev/video0 -qmax 2 http://localhost:8090/feed.ffm

    and it works (almost) as expected except that sometimes getting a jpeg hangs. I.e. a browser sends the GET request and... alles (de). If I in this case stop the ffmpeg then the browser reports an error, but if don’t touch anything the browser may wait a response very long time. In any case this behaviour is not acceptable for me : it could be better if the ffserver answers with any kind of error or something about this.

  • debian ffmpeg webcam streaming to remote server error

    13 mars 2016, par James

    I have a beaglebone black that I am trying to stream live video from, to an OSX computer. The streaming client potion seems to work if I point it to a local ffserver.

    and below is ffmpeg command to send my usb camera :

    ffmpeg running from my notebook with processor corei7 from Indonesia, and ffserver using ubuntu 14.x on ibm soflayer singapore,

    with above configuration i can play video streaming with 4s delay

    myquestion : howto improve speed so i can play video less than or equal 1 second, any idea ?
