  • 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" (...)

  • ffmpeg single output container with 4 audio channel to AWS IVS

    28 juillet 2021, par Yusufu

    Trying to send 1 video and 4 different audios to AWS IVS in single container. Which container or muxer should I use ?
FLV doesn't support multi audio, matroska doesn't support rtmp I guess link.
3GP and mp4 containers doesn't give me error but neither video showing on IVS

    


    For simple try I am using this command.

    


    ffmpeg -re -stream_loop -1 -i sample.mkv -r 30 -c:v libx264 -pix_fmt yuv420p -profile:v main -preset veryfast -x264opts "nal-hrd=cbr:no-scenecut" -minrate 3000 -maxrate 3000 -g 
60 -c:a aac -ac 2 -ar 44100 -vb 400k -maxrate 400k -minrate 400k -bufsize 800k -movflags frag_keyframe+empty_moov -f mp4 rtmps:someurls


    


    the above command doesn't include multi audio output so just trying to send except the flv format

    


  • FFMPEG concat video throws No Such Filter error

    5 janvier 2021, par Rohan Shah

    I am trying to concat three videos using FFMPEG,

    


    This is my command that I am executing using Java Runtime

    


        String command = "ffmpeg -i url_to_video -i url_to_video -i url_to_video -filter_complex [0:v] [0:a] [1:v] [1:a] [2:v] [2:a] concat=n=3:v=1:a=1 [v] [a] -map [v] -map [a] /home/rohan/output.mp4";

    Process process = Runtime.getRuntime().exec(command.split(" "));


    


    This is throwing me No Such Filter error, whereas if I try to run this via Terminal it works perfectly fine. I tried tweaking the cmd by removing or adding quotes, but any variant of this command that runs on terminal throws error in Java Runtime. While it runs perfectly on the Terminal.

    


    I have tried with Absolute paths and Amazon S3 URLs, while both of them work just fine in terminal, The S3 variant of command throws No Such Filter error and the Absolute path command throws a No Such File Or Directory error during Runtime.

    


    Here is the stack trace of the error

    


    Here is the standard error of the command (if any):

  • ffmpeg code not working aws lambda environment

    5 janvier 2021, par Akash Das

    I followed this article and deployed the Lambda functions and layers and set it up all fine.

    


    But I am facing a problem when I try converting the mp4 video into a 720p video, the ffmpeg commands that work in my Ubuntu 20.04 are not working in the Lambda and gives me error in the form of 0kb files in the destination folder.

    


    Can someone explain why this is happening ? The command that I used was :

    


    ffmpeg -i input.mp4 -s 1280x720 -c:a copy output.mp4


    


    I use this command in the Python file

    


    ffmpeg_cmd = "/opt/bin/ffmpeg -i \"" + s3_source_signed_url + "\" -f mp4 -s 1280x720 -c:a copy -" ___ . 


    


    This is the error I get :

    


    Errror

    


    The problem is that I used a code like this to get only the audio

    


    ffmpeg_cmd = "/opt/bin/ffmpeg -i \"" + s3_source_signed_url + "\" -f mp3 -ab 192000 -vn  -" ___ . 


    


    And it works as expected.
