  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Capture live video from a camera on a computer and using ffmpeg

    21 juin 2013, par Devendra

    I am trying to capture live video from a camera on a computer and using ffmpeg as an encoder, send this video for live streaming to a IIS server.

    Here is what I did :

    1. Captured feed from webcam using video4linux2 and ffmpeg

    2. Installed x264 for a h.264 codec

    3. Used muxer feature in ffmpeg, as described on this link -
      http://www.ffmpeg.org/ffmpeg-formats.html#Muxers
      to generate ismv file locally
      Command -
      ffmpeg -f video4linux2 -r 25 -s 640x480 -i /dev/video0 -b:v 661k -c:v libx264 -movflags isml+frag_keyframe+empty_moov -f ismv test.ismv

    4. Now to get the complete system in place (live capture from webcam and live streaming on IIS server), I want ffmpeg to generate this ffmpeg file on a publish point. here is the command I used
      ffmpeg -f video4linux2 -r 25 -s 640x480 -i /dev/video0 -b:v 661k -c:v libx264 -movflags isml+frag_keyframe+empty_moov -f ismv http://www.MY-SERVER/PushToPublishPoint/Test.isml

    as described at this link :

    http://www.unified-streaming.com/support/documentation/content-delivery/publishing-points/
    http://www.unified-streaming.com/support/documentation/content-encoding/encoders/

    It shows some video is being generated, but I cannot see any activity at the server.

    When I use wireshark to look at the packet info, there are many packet transfers between pc and the server.

    I have kept publishing point in IDLE state, STARTING state to see if that is the problem, but no progress there as well.
    I think I am unable to establish communication with the server. Pls help.

    Any help would be appreciated.

    Thanks

  • How to find currently streaming file in ffmpeg stream that uses a file list

    27 février 2021, par DigitalDisaster

    I am using ffmpeg to stream to an RTMP server. I am using the option to provide ffmpeg a text file with a list of files to stream. My file looks like this :

    


    ffconcat version 1.0
file 'stream_file1.flv'
file 'stream_file2.flv'
file 'stream_file3.flv'


    


    It loops through these files while streaming. Is there a way to programmatically find out when ffmpeg switches between each file ? Either from ffmpeg dumping some logs that I can injest, or by using python to check the state of the stream every second ?
