  • Création définitive du canal

    12 mars 2010, par

    Lorsque votre demande est validée, vous pouvez alors procéder à la création proprement dite du canal. Chaque canal est un site à part entière placé sous votre responsabilité. Les administrateurs de la plateforme n’y ont aucun accès.
    A la validation, vous recevez un email vous invitant donc à créer votre canal.
    Pour ce faire il vous suffit de vous rendre à son adresse, dans notre exemple "http://votre_sous_domaine.mediaspip.net".

  • Récupération d’informations sur le site maître à l’installation d’une instance

    26 novembre 2010, par

    Utilité
    Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
    Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • Download M3U8 That Is Playable

    15 octobre 2022, par Devin Dixon

    I am trying to download a livestream from this traffic camera source : https://vss1live.dot.ga.gov/lo/alph-cam-002.stream/playlist.m3u8

    


    The ffmpeg I am using is :

    


    ffmpeg -i https://vss1live.dot.ga.gov/lo/alph-cam-002.stream/playlist.m3u8 -preset slow -codec:a libfdk_aac -b:a 128k -codec:v libx264 -pix_fmt yuv420p -b:v 4500k -minrate 4500k -maxrate 9000k -bufsize 9000k -vf scale=-1:720 test.mp4


    


    And here are the logs when I quit the recording :

    Except the video doesn't seem to be playable by VLC or Quicktime. Given that the stream can end at any moment thus ending the file, how do I make the file actually playable ?

    


  • how to download sample-aes m3u8 with ffmpeg ? [hls prompts : Unable to open key file skd:xxxxxxx]

    18 octobre 2024, par Mam Ghagh

    I am newbie in programming and need help.
    
Story and Question -> I have a m3u8 manifest like :

    


    #EXTM3U
#EXT-X-VERSION:5
#EXT-X-TARGETDURATION:7
#EXT-X-PLAYLIST-TYPE:VOD
#EXT-X-KEY:METHOD=SAMPLE-AES,URI="skd://xxxxxx",IV=yyyyyyy,KEYFORMAT="com.apple.streamingkeydelivery",KEYFORMATVERSIONS="1"
#EXTINF:6,
https://someurl.com/index_1_0.ts
#EXTINF:6,
https://someurl.com/index_2_0.ts
...


    


    which is available on https://someurl.com/my.m3u8
    
So, When I executed ffmpeg command
    
ffmpeg -i "https://someurl.com/my.m3u8" -c copy out.mp4
    
the following message appeared
    
[hls @ 000002de75f89bc0] Unable to open key file skd://xxxxxx
    
Now the question is, How should I address the key ? Should I save the key into a file and address it in the m3u8 manifest ? or any other answer ?

    


  • What is causing "unspecified pixel format" and "Error opening filters !" error in ffmpeg ?

Error opening filters!

    The error says to try increasing analyzeduration and probesize, which I set to max value (based on an answer from this post), however that didn’t seem to change the behavior. I also suspected that the file was corrupted, but the fact that this is failing for all files larger than 7GB makes it more difficult to suggest its something not related to the size of the mp4.
