  • 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.

  • ffserver leave original stream size

    28 novembre 2014, par ihnatkuk

    Hope you guys will help me, because I have got stuck and can’t find solution for this problem by myself.
    I am trying to stream video from webcam to users using ffmpeg+ffserver. But I have faced with a problem :

    ffmpeg gets stream from camera and pushes it to feed of ffserver:
    
ffmpeg -rtsp_transport tcp -i rtsp://admin:admin@192.168.10.76:80 -y -vcodec libvpx http://127.0.0.1:8090/1.ffm

    ffserver stream options :

    <stream>
    
Feed 1.ffm
    
Format webm
    
NoAudio
    
#VideoCodec libvpx
    
#VideoSize 480x320
    
VideoFrameRate 24
    
AVOptionVideo flags +global_header
    
AVOptionVideo cpu-used 0
    
AVOptionVideo qmin 1
    
AVOptionVideo qmax 31
    
AVOptionVideo quality good
    
PreRoll 0
    
StartSendOnKey
    
VideoBitRate 128
    
</stream>

    (note, videoSize option is commented). But even with default VideoSize (160x128), ffserver doesn’t respond for each request. Browser always gets :

    HTTP/1.0 200 OK
    
Pragma: no-cache
    
Content-Type: video/webm

    But sometimes video content is not sent.

    If I uncomment VideoSize option - the same problem but much less successfull requests comparing with default video size.

    ffserver log looks regular with no errors. But as you can see that sometimes it sends only headers to client :

    Thu Nov 27 12:49:11 2014 127.0.0.1 - - [POST] "/1.ffm HTTP/1.1" 200 459

Thu Nov 27 13:30:58 2014 127.0.0.1 - - [POST] "/1.ffm HTTP/1.1" 200 622592

    Does anybody know what could it be ? Actually I need to save original VideoSize for stream. I am trying to override ffserver stream options with ffmpeg using the command (passing the same parameters as in ffserver’s stream) :

    ffmpeg -re -override_ffserver -rtsp_transport tcp -i rtsp://admin:admin@192.168.10.76:80 -an -r 24 -qmin 1 -qmax 31 -cpu-used 0 -quality good -flags:v +global_header -b:v 128 -vcodec libvpx -f webm -y http://127.0.0.1:8090/1.ffm

    But at the momment I still have error message ’Output file is empty, nothing was encoded’. Here is ffmpeg’s output :

  • Ffmpeg command to upload output to S3 using AWS CLI [closed]

    10 novembre 2020, par kmrinmoy07

    I have been trying to upload the output of ffmpeg into S3 using ASW CLI as shown in this post, but this works for video only. Can you give me a ffmpeg command which works for audio files for changing its quality.
