  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • rtmp : Rename packet types to closer match the spec

    31 janvier 2017, par Martin Storsjö
    rtmp : Rename packet types to closer match the spec

    Also rename comments and log messages accordingly,
    
and add clarifying comments for some hardcoded values.
    

    The previous names were taken from older, reverse engineered
    
references.
    

    These names match the official public rtmp specification, and
    
matches the names used by wirecast in annotating captured
    
streams. These names also avoid hardcoding the roles of server
    
and client, since the handling of them is irrelevant of whether
    
we act as server or client.
    

    The RTMP_PT_PING type maps to RTMP_PT_USER_CONTROL.
    

    The SERVER_BW and CLIENT_BW types are a bit more intertwined ;
    
RTMP_PT_SERVER_BW maps to RTMP_PT_WINDOW_ACK_SIZE and
    
RTMP_PT_CLIENT_BW maps to RTMP_PT_SET_PEER_BW.

  • ffmpeg : Time information does not match video duration

    8 novembre 2017, par Harry Developer

    I’m using tvheadend to record broadcasts to disc (running ubuntu). Later, I’m playing the files using players like MX Videoplayer or IJK player. Sometimes, the time information of the media files is weired. E.g., using

    ffprobe -i some-file.ts

    shows a lenght of 10 hours or even 20 hours, although the recording is only 2 hours long. Is this a ffmpeg bug ? What can be done to get the correct media length ?

    Here is the ffprobe output of the original file after recording it on disc :

  • FFMpeg Stream specifier no match

    11 mars 2019, par Amorphis

    Im trying to combine 2 to n videos with various transitions with an audio from mp3 above them (last second is faded).
