  • Les statuts des instances de mutualisation

    13 mars 2010, par

    Pour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.
    Les différents statuts possibles sont : prepa (demandé) qui correspond à une instance demandée par un utilisateur. Si le site a déjà été créé par le passé, il est passé en mode désactivé. publie (validé) qui correspond à une instance validée par un (...)

  • Concatenating videos Audio/Video out of sync : Non-monotonous TDS output

    6 août 2020, par invider

    I am trying to add two videos using ffmpeg and the output video/audio is out of sync (and fast forwarded). Goal is to put intro.mp4 before the original file clip.flv

    



    My approach is to

    



      

    1. Change the format of clip.flv to clip.mp4

      2. 


    



    ffmpeg -i clip.flv -q 0 -c copy clip.mp4


    



      

    1. Concat intro.mp4 with clip.mp4

      2. 


    



    ffmpeg -f concat -safe 0 -i filesToJoin.txt -c copy combinedvideo.mp4


    



    I see this in output log for command#2

    



    [mp4 @ 0x3ebcd60] Non-monotonous DTS in output stream 0:0; previous: 392311, current: 391925; changing to 392312. This may result in incorrect timestamps in the output file.

    Things I have tried

    



      

    • As you'll see that the both videos have same frame rate but different timescale, I have tried changing the timescale of one of the video to match the other before combining the video but with no luck. For timescale change I used this command

      • 


    



    ffmpeg -i clip.mp4 -video_track_timescale 30000 clip_ts30000.mp4

    



      

    • I have seen the similar questions on SO, no luck

  • ffmpeg : incorrect parameters such as bit_rate, rate, width or height

    24 octobre 2020, par Tombart

    I'm trying to convert mp4 to mov, however ffmpeg is having issues with the video conversion :

    


      Stream #0:0 -> #0:0 (h264 (native) -> dnxhd (native))


    


    I've tried several of suggested configuration without success. Any idea what's wrong ? How do I choose "correct" video format ?
