  • 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" (...)

    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...

  • Bash script : Cycle script until ffmpeg command restarts successfully

    13 août 2023, par Bellacoda

    I have a IP Camera and the recordings are saved with ffmpeg RTSP into a raspberry pi.

    


    Sometimes, when the electricity shuts off and comes back on, the raspberry boots faster than the IP Camera and the ffmpeg command (saved on a crontab to run every reboot) fails to execute because it can't reach the IP Camera (that is still turning on).

    


    I tried to put a sleep command before the command but that doesn't work either.

    


    It also happened that when the IP Camera reboots, the raspberry closes the command, but when the camera comes back online, I have to manually lauch the command.

    


    Is there a way to make a script that waits to run the ffmpeg command until the camera is fully online (I assume with the $ ? variable for command exit status), and to wait to restart the ffmpeg command when the camera reboots ?

    


    The setup I have now is a crontab :
SHELL=/bin/bash
@reboot sleep 120s ; sudo ffmpeg ...

    


  • Cut video command producing only audio

    12 février 2018, par Sandeep

    I am using ffmpeg in Android app and my command code looks like :

          final String[] command=new String[]{"-i",inputFileName , "-ss",
    
 String.valueOf(duration) , "-codec","copy", "-t",String.valueOf(start) , outputFileName};

    The logcat contains following ffmpeg output which shows video as 0kB in last line. Where should I look for fixing this because the final output file is a mp4 file but the video content is missing and only audio is present for the trimmed duration :

  • FFMPEG command runs if I am not using a specific input

    16 août 2022, par sivafe9540

    the following ffmpeg command would run if I was to switch the -loop 1 -t 10 -i image.png (which allows me to take an image and make it a ten second video) to normal video input, like input1.mp4...

    


    Here is the command that does not work :

    


    ffmpeg -loop 1 -t 10 -i image.png -f lavfi -i input2.png -filter_complex "[0:v][1:v] overlay=W-w:600" -pix_fmt yuv420p -c:a copy -shortest output.mp4


    


    Here is the command that proves -loop 1 -t 10 -i image.png is the problem because it works without it.

    


    ffmpeg -i input1.mp4 -f lavfi -i input2.png -filter_complex "[0:v][1:v] overlay=W-w:600" -pix_fmt yuv420p -c:a copy -shortest output.mp4


    


    My theory

    


    My theory is that the input of the image that is being turned into a ten second video has to be rendered before the filter complex tries to overlay it but it is not... and I don't know hoe to do that.

    


    Non helpful error

    


    zsh: parse error near &'

    


    Requirement

    


    Please do not make solve this issue with more than one ffmpeg command.
