    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • De l’upload à la vidéo finale [version standalone]

    31 janvier 2010, par

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
    Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

  • ffmpeg take input and out put as webm on port

    28 septembre 2019, par RussellHarrower

    I am wondering how I can take an audio input and output it as a webm

    This is what I thought would work to get it to rtp out but running into issue.

     ffmpeg -i http://stream.radiomedia.com.au:8003/stream -c copy  -f rtp rtp://127.0.0.1/streamID:54321

  • python multiple threads redirecting stdout

    4 septembre 2022, par Marcin Kamienski

    I'm building an icecast2 radio station which will restream existing stations in lower quality. This program will generate multiple FFmpeg processes restreaming 24/7. For troubleshooting purposes, I would like to have an output of every FFmpeg process redirected to the separate file.

    


    import ffmpeg, csv
from threading import Thread

def run(name, mount, source):
icecast = "icecast://"+ICECAST2_USER+":"+ICECAST2_PASS+"@localhost:"+ICECAST2_PORT+"/"+mount
stream = (
        ffmpeg
        .input(source)
        .output(
            icecast,
            audio_bitrate=BITRATE, sample_rate=SAMPLE_RATE, format=FORMAT, acodec=CODEC,
            reconnect="1", reconnect_streamed="1", reconnect_at_eof="1", reconnect_delay_max="120",
            ice_name=name, ice_genre=source
            )
        )
return stream

with open('stations.csv', mode='r') as data:
for station in csv.DictReader(data):
    stream = run(station['name'], station['mount'], station['url'])
    thread = Thread(target=stream.run)
    thread.start()


    


    As I understand I can't redirect stdout of each thread separately, I also can't use ffmpeg reporting which is only configured by an environment variable. Do I have any other options ?

    


  • FFMPEG fails to stream from .m3u8 over HTTP

    16 mars 2017, par Parsa Samet

    FFMPEG will fail to stream from .m3u8 over HTTP. It is pointing to getting an empty playlist whilst it’s not empty. It also points to the following error sometimes :

    Failed to open segment of playlist 0.

    UPDATE :

    The command that I use :

    ffmpeg -re -i http://cdn.live.domain.tld:port/radio.stream/playlist.m3u8?wmsAuthSign=xyz -vn -codec:a libmp3lame -b:a 64k -f mp3 -content_type audio/mpeg icecast://"source":"password"@destinationIPorDomain:8000/mountPoint
