  • 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" (...)

  • interrupt and resume long running ffmpeg encoding

    17 octobre 2022, par simon

    When i have a longer high res video (full-hd or 4k) which are not compressed well, encoding to webm/vp9 can take very long even with a recent system due to the lack of hardware acceleration with webm/vp9.
Are there any options to interrupt an encoding with ffmpeg and resume which survives a reboot.
So i don't want to pause encoding using bg but save & stop encoding state and resume from there.

    


    The next best thing i could think of is to split the source into smaller subsets (by time) and process them and stitch results together again. But this only allows predefined interruption points and requires the split & merge to be done in addition.
On the pro side it could allow parallel processing if multithreading is not using all available cores yet.

    


  • Easiest method of compiling a finished MP4 video out of image bursts and video segments on Ubuntu ?

    14 juin 2017, par aschmelyun

    I need to programmatically stitch together a video out of bursts of images, and pre-recorded .mp4 video, on an Ubuntu system from the command line. So for example, here’s the ’recipe’ that I’m working with :

    1. 12 images
    2. 5 second video
    3. 12 more images
    4. 5 second video
    5. 5 second video
    6. 12 more images

    Right now what I’m doing is compiling the images into .mp4 videos using ffmpeg, and then using mp4box to concat all of these partial videos together into one final video. The unfortunate thing is that I’m having to keep track of and run multiple commands to do this (the example above using 4 separate commands). Is there any way to simplify this, or is this the most efficient method I can expect ?

  • Too many inputs specified for the "split" filter

    3 octobre 2018, par Sasidharan S

    I just tried to stitch 2 files and tried to get multiple outputs parallely :

    ffmpeg -i 1.mp4 -i 2.mp4 -filter_complex "[0:v:0] [0:a:0] [1:v:0] [1:a:0] concat=n=2:v=1:a=1, split=2[out1][out2]" -map '[out1]' -preset ultrafast -vn -b:a 128k -c:a aac  tes45.mp4 -map '[out2]' -preset ultrafast -vn -b:a 128k -c:a aac  tes46.mp4

    But it didn’t work :

    Too many inputs specified for the "split" filter.
    
Error initializing complex filters.
    
Invalid argument
