  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • streaming data with ffmpeg using pipe - freeze after few seconds

    13 octobre 2022, par tamirg

    Im fetching some video data, and trying to stream it using ffmpeg.
what i do is create an ffmpeg process, set it to get info from '-', and then when i fetch the video data i write it to the process STDIN.

    


    My problem is that its working, but only working for around 3 seconds, then the stream stops, and there are no longer any logs from ffmpeg.

    


    Im running ffmpeg with log level debug, and it seems to parse the data ok, which i guess thats why it works for 3 seconds, but then the ffmpeg stops printing any more logs.

    


    I dont want to attach all the logs because its too much, but ill write the main parts.
Maybe the ffmpeg process is missing some arguments ?

    


    It starts with :

  • FFMPEG fails with seeking params before input on AWS Lambda

    18 janvier 2023, par Rashid Goshtasbi

    I am trying to run the following command on AWS Lambda that has FFMPEG layer but it fails with a SIGSEGV. The FFMPEG process starts working fine until it reaches the segment's it wants to get.

    


    /opt/ffmpeglib/ffmpeg -ss 00:02:00 -t 30 -i https://cdn.bitmovin.com/content/assets/art-of-motion-dash-hls-progressive/m3u8s/f08e80da-bf1d-4e3d-8899-f0f6155f6efa-audio-only.m3u8 /tmp/out.aac -y


    


    Note : The url is a sample url for this sharing

    


    What this is doing : It will seek 2 minutes into the stream url, then capture the next 30 seconds into an out.aac file. When I run this locally, it works fine. When I run this on Lambda, it ends abruptly when reading the segments that are in the time frame I want (from 2:00min to 2:30 min).

    


    FFMPEG will skip the frames if I put the -ss 00:02:00 -t 30 before the -i which they state is faster. If i put it after the -i, it works, but of course, it's a bit slower.

    


    Example working command :

    


    /opt/ffmpeglib/ffmpeg -i https://cdn.bitmovin.com/content/assets/art-of-motion-dash-hls-progressive/m3u8s/f08e80da-bf1d-4e3d-8899-f0f6155f6efa-audio-only.m3u8 -ss 00:02:00 -t 30 /tmp/out.aac -y


    


    Wondering if anyone knows a way to run this on Lambda. Thank you.

    


    Note : I have tried this on Python and Javascript. Tried also making child processes with Javascript and no luck. I also added -nostdin and piped stdin/out to dev null but nothing.

    


    Thanks.

    


    Example of me running locally :

  • batch scripting help passing arguments to ffmpeg

    20 octobre 2022, par notsolowki

    I need to join some videos parts together into 1 part. Im working from a folder called series. series contains multiple subfolder 1,2,3,4 etc that represent video number. each sub folder contains the parts to be joined together.

    


    I made a batch script that seems to be able to make a list of sub directories and make a list of sub directory contents,

    


    however run i run the script and try to pass the information from "mylist" line by line to ffmpeg it dont seem to work it complains invalid input information detected.

    


    I intended for the batch script to start at folder 1 and pass the file names from "mylist.txt" to ffmpeg input 1 by one untill the last folder in folderlist.txt is processed.

    


    What am i doing wrong. how can i make this script work ?

    


        :: Create File List
for /D %%G in ("%cd%\*")DO ( 

for %%i in ("%%~nxG"\*.mp4) do echo file '%%i'>> mylist.txt
echo %%~nxG >> folderlist.txt

)

:: Concatenate Files
::for /F "delims=" %%a in (mylist.txt) do (
ffmpeg -f concat -safe 0 -i %%a -c copy %%a.mp4
::)
pause
@echo off


pause


    


    the error i get when i run it from ffmpeg after running the batch is,

    


    C:\Users\Laptop\Desktop\t10>(ffmpeg -f concat -safe 0 -i "file '4\Tosh.0 April 17  2018 10 1004 April 17  2018 - Ticket Girl Act 1.mp4'" -c copy file '4\Tosh.0 April 17  2018 10 1004 April 17  2018 - Ticket Girl Act 1.mp4'.mp4 )
