    Préambule
    Cet article n’a pas pour but de détailler les installations de ces logiciels mais plutôt de donner des informations sur leur configuration spécifique.
    Avant toute chose SPIPMotion tout comme MediaSPIP est fait pour tourner sur des distributions Linux de type Debian ou dérivées (Ubuntu...). Les documentations de ce site se réfèrent donc à ces distributions. Il est également possible de l’utiliser sur d’autres distributions Linux mais aucune garantie de bon fonctionnement n’est possible.

  • Can pyAudioAnalysis be used on a live http audio stream ?

    30 mars 2022, par Tompo

    I am trying to use pyAudioAnalysis to analyse an audio stream in real-time from a HTTP stream. My goal is to use the Zero Crossing Rate (ZCR) and other methods in this library to identify events in the stream.

    


    pyAudioAnalysis only supports input from a file but converting a http stream to a .wav will create a large overhead and temporary file management I would like to avoid.

    


    My method is as follows :

    


    Using ffmpeg I was able to get the raw audio bytes into a subprocess pipe.

    


    try:
    song = subprocess.Popen(["ffmpeg", "-i", "https://media-url/example", "-acodec", "pcm_s16le", "-ac", "1", "-f", "wav", "pipe:1"],
                            stdout=subprocess.PIPE)


    


    I then buffered this data using pyAudio with the hope of being able to use the bytes in pyAudioAnalysis

    


    CHUNK = 65536

p = pyaudio.PyAudio()

stream = p.open(format=pyaudio.paInt16,
                channels=1,
                rate=44100,
                output=True)

data = song.stdout.read(CHUNK)

while len(data) > 0:
    stream.write(data)
    data = song.stdout.read(CHUNK)


    


    However, inputting this data output into AudioBasicIO.read_audio_generic() produces an empty numpy array.

    


    Is there a valid solution to this problem without temporary file creation ?

    


  • avformat/hlsenc : Extend persistent http connections to playlists

    15 décembre 2017, par Karthick J
    avformat/hlsenc : Extend persistent http connections to playlists

    Before this patch persistent http connections would work only for media segments.
    
The playlists were still opening a new connection everytime.
    
This patch extends persistent http connections to playlists as well.
