    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 (...)

  • Minutes and seconds as variabe in Python

    7 avril 2014, par Badr Hari

    How can I store hours/minutes/seconds as variable in python ?

    For example :

    time = "01:30" # 1 minute and 30 seconds
    
time2 = time + 10 seconds

    Basically a program (using FFMPEG) will decide when to start playing an audio file but the value can be changed in +-10 seconds, the questions is how can I store this value.

    Last try to clarify my question :
    time variable is "01:30" which clearly represent the time, 01 min 30 seconds, how can I add 10 seconds to it to make the variable 10:40, clearly 01:30+:00:10 is not the solution.

    Sorry for confusion folks, I do my best.

  • How to split streaming video into pieces FFMPEG

    17 juin 2019, par danilshik

    I have a bat script (Windows) for the library Livestreamer to record the broadcast in the video

    :loop
    

    
set day=%DATE:~0,2%
    
set month=%DATE:~3,2%
    
set year=%DATE:~6,4%
    

    
set hour=%TIME:~0,2%
    
set minute=%TIME:~3,2%
    
set second=%TIME:~6,2%
    

    
set YYYYMMDD=%day%_%month%_%year%_%hour%_%minute%_%second%
    

    

    
streamlink --hls-live-edge 99999 --hls-segment-threads 10 --ringbuffer-size 1024M -o %YYYYMMDD%.ts https://www.twitch.tv/silvername best
    
goto loop

    How can I break this video into pieces ?

    I tried to do so, but it did not work, writes the error of the arguments

    ffmpeg -i "streamlink --hls-live-edge 99999 --hls-segment-threads 10 --ringbuffer-size 1024M -o %YYYYMMDD%.ts https://www.twitch.tv/manyrin best" -f segment -segment_time 1 -vcodec copy -acodec copy "%03d.ts"

  • 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) ?
