  • 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" (...)

  • Got incorrect audio duration from ffmpeg

    8 septembre 2021, par Remeraze

    I used an ffmpeg command to export parts of an audio clip :

    


    ffmpeg -i {path} -acodec copy -ss {start_time} -to {end_time} {output_path}


    


    Unfortunately, this has the side effect of not changing the time duration in the file's details section, making many programs I use think the time of the cut audio files is much more than it really is.

    


    Is there a way to either make ffmpeg change the duration, or find a command in python that can change an audio file's "length" stat so I can do it manually ? I couldn't find any way online.

    


    Thanks.

    


  • any solution to Matlab VideoReader on compressed avi file on Mac ?

    3 décembre 2016, par Peng JL-Zhulin

    I am working on some video gamma correction. And I used some sample avi uncompressed clips from online, everything works just fine.
    But once I try to use our own .avi video 1280x800 20 second about 400mb, Matlab can not read file through ’VideoReader’.

    I’m really sure the problem is that my video is compressed avi. And I have tried the following to solve it :

    1. some say in mac os, download gstreamer 0.10 may help. I did, but problem remained.
    2. i tried to use ffmpeg to convert the compressed avi to uncompressed avi (i dont think i am supposed to do this tho). but the new uncompressed video became a mess.

    So, I was thinking, when working on compressed avi file in MATLAB in mac, is there a godd routine that people follow ?

    Thanks a lot.

  • FFMPEG, any video to 16:9

    13 décembre 2019, par Universal

    Help me find a command or script that will convert any video to 16:9, h264 and 2500kbps. I have a server where people upload videos of different quality, size and length. It can be either 640x480 or 1216x2160. Ultimately, I need to get any resolution to 16:9 (with black borders, if needs) and bitrate without visible loss of quality, which will be acceptable for online broadcasting.

    I have this command, but it does not check the resolution of the video. And if the video was 560x448 1000kbps and 700mb, then after conversion it will be 1280x720 3000kbps and 1.5gb, that’s not right.

    ffmpeg -i 5.avi -vcodec libx264 -crf 23 -preset veryfast -vf scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:(ow-iw)/2:(oh-ih)/2,setsar=1 -tune zerolatency highoutput.mp4
