    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.

  • How to union RAW video data stream with RAW data audio stream through ffmpeg .net

    17 septembre 2022, par zabitstack

    I'm trying to union a raw video data stream with raw audio data stream but without success ! I capture video from webcam and audio from microphone in .net Accord Framework application.

    


    I want use ffmpeg core .net library to transform raw video data into a avi file, then same thing transform raw audio data into mp3 format file. Next merge mp3 with avi in single avi video+audio file.

    


    If you want, I can post source code how I capture data.

    


  • ReSample RTP Audio data over Socket as PCM data using FFMPEG

    5 février 2020, par GJ.

    I want to receive a RTP Stream and send the raw data received in it over TCP / UDP socket. For this i am trying following commands.

    1. I am sending the RTP stream using following command.

      ffmpeg -re -i hello.wav -ar 8000 -f mulaw -f rtp rtp ://127.0.0.1:1234

    2. Receiver to re transmit the stream over TCP / UDP socket.

      ffmpeg -i rtp ://127.0.0.1:1234 -f mulaw tcp ://127.0.0.1:5555 -hide_banner

    3. A Player to play this Socket stream to verify.

      ffplay tcp ://127.0.0.1:5555 ?listen

    My second command shows that its receiving data and transmitting the data to tcp over 5555 port.

    Input #0, rtp, from 'rtp://127.0.0.1:1234':
    
  Duration: N/A, start: 0.000000, bitrate: 64 kb/s
    
    Stream #0:0: Audio: pcm_mulaw, 8000 Hz, mono, s16, 64 kb/s
    
Stream mapping:
    
  Stream #0:0 -> #0:0 (pcm_mulaw (native) -> pcm_mulaw (native))
    
Press [q] to stop, [?] for help
    
Output #0, mulaw, to 'tcp://127.0.0.1:5555':
    
  Metadata:
    
    encoder         : Lavf58.29.100
    
    Stream #0:0: Audio: pcm_mulaw, 8000 Hz, mono, s16, 64 kb/s
    
    Metadata:
    
      encoder         : Lavc58.54.100 pcm_mulaw

    But the third command does not receive anything, even i tried dumping the response into a file using FFMPEG in command three but same results.

    What am i doing wrong, Please suggest the correct commands using FFMPEG.
