  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • ffmpeg : error while loading shared libraries : libmp3lame.so.0 : cannot open shared object file : No such file or directory

    17 février 2021, par GetItDone

    I am using this buildpack (heroku-python-buildpack-ffmpeg-lame) for my app on heroku that uses ffmpeg to convert uploaded videos to .mp4. I had been using the version without libmp3lame, and since I switched I am getting the error

    



    ffmpeg: error while loading shared libraries: libmp3lame.so.0: cannot open shared object file: No such file or directory


    



    I checked to see where libmp3lame.so.0 is located on my server with heroku run —app myapp find / -name libmp3lame.so.0, and the resulting path was /app/vendor/lame/lib/libmp3lame.so.0. I tried adding /vendor/lame/lib to my heroku path using the heroku config:set command, but even after adding it I still get the same error. Anyone know what the problem could be ?

  • Does Facebook multicast or unicast the live videos to its viewers ?

    14 avril 2018, par Kamran Zahoor

    This is how a live stream goes from one broadcaster to millions of viewers :

    1. A broadcaster starts a live video on their phone.
    2. The phone sends a RTMP stream to a Live Stream server.
    3. The Live Stream server decodes the video and transcodes to multiple bit rates.
    4. For each bit rate a set of one-second MPEG-DASH segments is continuously produced.
    5. Segments are stored in a datacenter cache.
    6. From the datacenter cache segments are sent to caches located in the points of presence (a PoP cache).
    7. On the view side the viewer receives a Live Story.
    8. The player on their device starts fetching segments from a PoP cache at a rate of one per second.

    My question is simple. After the step 6, does PoP cache/Edge cache/eNB (edge layer node) multicast a live video content to multiple viewers or unicast each user separately (opening up seperate streams for each user) ?
