  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.

  • Transcode Webm to Audio file (fluent-ffmpeg)

    3 juillet 2017, par shamaleyte

    I have a video file and its properties are as the following when I check via the ffprobe command ;
    My purpose is to take the audio file only and its size should not be >100mb.
    Is there any proper way of doing it in an NPM project ?

    ffprobe 2.webm

  • What is the best way to merge .mkv and .mka files using ffmpeg ?

    28 juin 2017, par Robert

    I’m using ffmpeg to merge .mkv and .mka files into .mp4 files. My current command looks like this :

    ffmpeg -i video.mkv -i audio.mka output_path.mp4

    The audio and video files are pre-signed urls from Amazon S3. Even on a server with sufficient resources, this process is going very slowly. I’ve researched situations where you can tell ffmpeg to skip re-encoding each frame, but I think that in my situation it actually does need to re-encode each frame.

    I’ve downloaded 2 sample files to my macbook pro and have installed ffmpeg locally via homebrew. When I run the command

    ffmpeg -i video.mkv -i audio.mka -c copy output.mp4

    I get the following output :

    Last message repeated 1 times

    So it appears that the specific encodings I’m working with are vp8 videos and opus audio files, which I believe are incompatible with the .mp4 output container. I would appreciate answers that cover ways of optimally merging vp8 and opus into .mp4 output or answers that point me in the direction of output media formats that are both compatible with vp8 & opus and are playable on web and mobile devices so that I can bypass the re-encoding step altogether.

    EDIT :

    Just wanted to provide a benchmark after following LordNeckbeard’s advice :

    4 min 41 second video transcoded locally on my mac
    

    
LordNeckbeard’s approach : 15 mins 55 seconds (955 seconds)
    
Current approach : 18 mins 49 seconds (1129 seconds)

  • ffmpeg HLS transcoding and chunks upload to remote server

    25 mai 2020, par Georgе Stoyanov

    I am trying to create a so called origin server for storing the hls chunks and the manifest file on a remote server. The sending machine running ffmpeg is with IP : 192.168.178.50 and the web server which has to store both the HLS chunks and the manifest file is with IP : 192.168.178.100. My ffmpeg transcoding command line is :

    But no matter what method I am using I got in the access log of my apache web server the following errors :

    



    $ tail -f /var/log/apache2/access.log

    These are the supported methods on my web server :

    My web server is running apache2 on Ubuntu 16.04 :

    



    $ apache2 -v

Server version: Apache/2.4.18 (Ubuntu)
Server built:   2017-06-26T11:58:04


    



    So according to the access.log file no matter what method I define in the ffmpeg command line it is always trying to upload the chunks using HTTP POST, but the latter is already supported and the directory I am directing the chunks has even 777 rights. Am I missing something here ?
