  • 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.

  • 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.

  • Streaming trouble, ffmpeg unable to find a suitable output format

    9 octobre 2018, par Michael Munyanyi

    FFMPEG for some odd reason won’t allow me to output a stream, it’s odd because I have two computers available and one, which had low CPU was having trouble decoding but the stream worked, so I switched my network cables and I have tried transcoding with the same command and it will not output a stream.

    My command reads

    ffmpeg -i udp://@xxx.x.x.xx.xxxx -f mpegts udp://@xxx.x.x.xx.xxxx

    I also tried

    ffmpeg -i udp://@xxx.x.x.xx.xxxx udp://@xxx.x.x.xx.xxxx

    The error reads

    [NULL @ 000001c95eeb2600] Unable to find a suitable output format for udp://@xxx.x.x.xx.xxxx'
    
udp://@xxx.x.x.xx.xxxx: Invalid argument"

  • FFMPEG Concat filter - Output video skips second file

    16 octobre 2018, par Rune Aspvik

    I am using the ffmpeg concat filter to join video files. I am aware the files must be exactly the same format for concat to work without encoding. However, the output of these two files are not seemless. The video will stop when it switches to second video file.

    Here is the output of the two video files.

    The command I’m using for the concat is :

    ffmpeg -f concat -safe 0 -i /Users/Aspvik/Desktop/files.txt -codec copy -y /Users/Aspvik/Desktop/video.mp4

    Can anyone see what could be wrong ?

  • FFMPEG output duration using "-t" is too long by 10 ms

    9 octobre 2018, par Ze'ev

    I’m using this command to take video from a 35 second QuickTime file and replace audio with a WAV :

    ffmpeg -i 'video.mov' -i 'audio.wav' -c:v copy -c:a copy -map 0:v:0 -map 1:a:0 -t 35.0000 'output.mov'

    But the audio is slightly longer than the video, and I’m trying to make ffmpeg trim the output to exactly 35 seconds with -t 35 but the output is 35.01 seconds.

    I also tried -t 35.000 and -to 35 and several other options, but it’s alway 10ms too long.
