  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • libxvid : Require availability of mkstemp()

    libxvid : Require availability of mkstemp()

    The replacement code uses tempnam(), which is dangerous.
    
Such a fringe feature is not worth the trouble.

  • Why FFmpeg is consuming more and more bandwith when restreaming a YouTube HLS stream ?

    3 janvier 2023, par NiHuShu

    I've been creating a bot in Python which allows to copy one YouTube livestream and stream it to another channel using the HLS protocol.

    


    This is the command I'm using in Python to start the FFmpeg process :

    


    m3u8_url = streamlink.streams(stream_url)['1080p'].url
ffmpeg_process = Popen(
    ["ffmpeg", "-i", m3u8_url, "-c", "copy","-ignore_io_errors", "1", "-f", "hls", "-http_persistent", "1", '-attempt_recovery', '1',
    '-method', 'POST', '-hls_time', '1', '-hls_playlist_type', 'event', '-g', '5', '-reconnect_at_eof', '1',
    'https://a.upload.youtube.com/http_upload_hls?cid=' + stream_key + '&copy=0&file=stream.m3u8'])


    


    I'm using streamlink to extract the 1080p m3u8 playlist of a given livestream and then using "-c", "copy"I'm just passing the raw HLS stream back to YouTube servers.

    


    The problem is that at first FFmpeg is using around 1.5 Mbps for both upload and download, but as the stream progresses the used bandwidth per second grows substantially. After 5 hours FFmpeg uses 5 Mbps of upload and about half of that in download, but it just keeps on growing. It's gotten to a point where my VPS was blocked as after a few days it was using > 1500 Mbps of bandwidth (with 10 active streams).

    


    The only thing that comes to my mind is that for some reason with every .ts segment, FFmpeg is trying to send all the previous ones as well. It might be worth mentioning that YouTube Studio is complaining that the incoming stream bandwith is too low and it should be 4.5 Mbps.

    


    I've tried changing the "-method" from PUT to POST, which helped reducing the download bandwidth, but didn't change anything in regards to upload.

    


  • ffmpeg tcp error -138 and HTTP error 503 while downloading from https source

    15 juin 2022, par PeterM

    i'm trying to download media (video) files from sharepoint (i have view access), but during the process i get several "Connection to tcp ://xxx.xxxxx.ms:443 failed : Error number -138 occurred" or "HTTP error 503 Service Unavailable" errors

    


    tcp error

    


    HTTP error 503

    


    i get more errors with the following parameters :

    


    ffmpeg -i "https://theURLtoTheManifestYouCopiedHere" -codec copy downloadedVideo.mp4


    


    less errors with :

    


    ffmpeg -re -vsync 1 -i "https://theURLtoTheManifestYouCopiedHere" -codec copy downloadedVideo.mp4


    


    the options suggested in this article didn't help : https://medium.com/intrasonics/robust-continuous-audio-recording-c1948895bb49

    


    the output video is ok, but sound seems to be missing occasionally (a few seconds worth)

    


    ffmpeg version 2022-06-12-git-4d45f5acbd-essentials_build-www.gyan.dev

    


    any advice ?
