  • 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.

  • FFmpeg scaling issue

    12 janvier 2018, par DonX

    I am trying to down scale a video from 607x1080 to 440 width with the height automatically being calculated using the following command. It does scale the video but not to the specified dimension. The video is scaled to 216x384 even though the output below indicates 440x384.

    ffmpeg -i video.mp4 -vf scale=440:-2 -c:v libx264 -c:a aac -y video-out.mp4

    The output is as follows :

    I did some searching and learned this may be an issue scaling with libx264 codec and the input width being an odd number ? If so, is there a workaround so get the video to scale to the specified size ? Thank you.

  • Recording screencast using ffmpeg produces audio that is out of sync with the video

    7 décembre 2014, par AgilE

    I’m on Fedora 20. I got it pre-compiled from the repo.

    I use the follow command to record screencasts :

    ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 30 -s 1366x768 -i :0.0 -acodec pcm_s16le -vcodec libx264 -preset ultrafast -crf 0 -threads 0 filename.mkv

    The audio is perfectly synced with the video at the beginning. However, as the video progresses, the audio starts lagging behind severely (say a lag of more than 4 seconds). I’ve included a sample output that ffmpeg shows while recording a video.

  • FFmpeg wrong duration(double) when convert mp4

    13 novembre 2017, par crazymxm

    The output file has the double duration :

    Source video duration :00:01:58.88

    output video duration :00:03:57.76

    （video’s duration is double ，audio’s duration is correct. So， the video looks like played twice, with no sound in the second half ）

    here is the log：
