  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Evolution #3498 : 3.1 : SPIP 3.1.0-beta [22291] SVP (bouton "version obsolete")

    4 juillet 2015, par b b

    Dans l’ordre :

    1) les blocs "short" ne débordent pas chez moi (voir image jointe) et ils n’ont pas de padding appliqué.

    2) le warning que tu signales est dans la fonction verifier du formulaire, tu as donc lancé une action pour l’obtenir ? Un peu plus d’infos sur le contexte aiderait à cerner le bug...

    3) aucune idée.

  • can I set a filter on by default within ffmpeg ?

    13 septembre 2013, par user195789

    For example, the default filter for video encoding in FFMPEG is libx264... I would like to either configure via an environment variable, a build/compile option, or something else that unless I specify otherwise the yadif de-interlace filter is always turned on when encoding.

    Anyone know if this is possible, short of significantly modifying the source code (which is almost certainly beyond my abilities)

  • FFMPEG Audio/video out of sync after cutting and concatonating

    31 janvier 2020, par Ham789

    I am attempting to take cuts from a set of videos and concatonate them together with the concat demuxer.

    However, each video’s audio is out of sync in the output. At the beggening of each clip there is a short period of silence before the audio begins.

    For each video, I decode it, trim a clip from it and then encode it to 4k resolution at 25 fps with its audio :

    ffmpeg -ss 0.5 -t 0.5 -i input_video1.mp4 -r 25 -vf scale=3840:2160 output_video1.mp4

    I then take each of these videos and concatonate them together with the concat demuxer :

    ffmpeg -f concat -safe 0 -i cut_videos.txt -c copy -y output.mp4

    I am taking short cuts of each video (approximately 0.5s)

    I am using Python’s subprocess to automate the cutting and concatonating of the videos.

    It seems the audio becomes out of sync after the trimming step (not the concatonation) as when I play back the intermediate cut video files (output_video1.mp4 in the above code), there seems to be the same silence before the audio comes in at the start of the video.

    When I concatonate the videos, I get a lot of these warnings :

    [mp4 @ 0000021a252ce080] Non-monotonous DTS in output stream 0:1; previous: 51792, current: 50009; changing to 51793. This may result in incorrect timestamps in the output file.

    From this post, it seems to be a problem with cutting the videos and their timestamps. The solution proposed in the post is to decode, cut and then encode the video however I am already doing that.

    How can I ensure the audio and video are in sync ?
