  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • ffmpeg performance with hundreds of cuts (atrim)

    25 mai 2021, par drakon

    I have audio files (think 2h) where I want to cut out a lot of pieces out of it (500+) and a ffmpeg command like this one :

    


    ['ffmpeg', '-i', 'pipe:', '-filter_complex', 
'[0]atrim=end=30.69:start=0.0[s0];
 [0]atrim=end=34.31:start=31.18[s1];
 [0]atrim=end=38.65:start=34.43[s2]; 
 (... hundreds more)
 [s37][s38][s39][s40][s41]concat=a=1:n=42:v=0[s42]', '-map', '[s42]']


    


    Stream mapping built with ffmpeg-python :

    


      Stream #0:0 (mp3float) -> atrim
  (... hundreds more)
  Stream #0:0 (mp3float) -> atrim
  concat -> Stream #0:0 (libmp3lame)


    


    Now this works as expected but it takes locally something like 10mins for the files I have and when I deploy it to some server in the cloud it takes something like an hour. It definitely depends on the machine obviously and I definitely scale there the speed but I'd also like to know if there's a way to speed up the processing with ffmpeg itself.

    


    Thanks for any pointers !

    


  • FFmpeg Unknown Input Format 'gdigrab'

    14 décembre 2020, par Jim

    I'm trying to use FFmpeg to stream my screen in a spawned process in NodeJS. I downloaded v4.3.1 on my Windows 10 machine and when I tried to use the command ffmpeg -f gdigrab -framerate 30 -i desktop out.mpg I get an error saying :

    


    Unknown input format: 'gdigrab'
Conversion failed!


    


    I also tried using dshow (ffmpeg -f dshow video="UScreenCapture" output.mkv) and received the error :

    


    [dshow @ 0000000000002734560] Could not find video device
video=UScreenCapture: Input/output error


    


  • FFServer does not stop

    18 mai 2014, par user3235818

    I am trying to stream video from my webcam to a website that I created, using FFMpeg and FFServer on my Ubuntu 12.04 machine. I can successfully start FFServer with an ffserver1.conf file I’ve made, but when I stop FFServer (with crtl+c) to make changes to my config file, and try to start FFServer again, I get an error : Could not start server. Then I try to start the server with the default ffserver.conf (in /etc), I get an error : bind(port 8090) : Address already in use. Sometimes I also get Deleting feed file "/tmp/feed1.ffm’ as stream counts differ (4 != 1).

    It seems to me that the server is not completely stopping when I kill it in the terminal with ctrl+c. Is there another way to stop FFServer ? Or should I just get a different version - I’m currently using version 0.10.11-7:0.10.11-1 precisce1.

    Thank you
