  • 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" (...)

  • How to loop over gif file finite number of times while creating mp4 as output with ffmpeg

    16 mai 2020, par in-user

    I am able to convert gif file to mp4 using this command :

    



    ffmpeg -i animated.gif -movflags faststart -pix_fmt yuv420p -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" video.mp4


    



    What I want to do is to loop over gif animation 3 times and convert to mp4.

    



    I am able to do this with 2 shell commands. First one from above and then concatenate the same video 3 times.

    



    ffmpeg -f concat -safe 0 -i <(printf "file '$PWD/video.mp4'\n%.0s" {1..3}) -c copy videoloop.mp4


    



    I have also tried with -ignore_loop 0 option and setting time. It does work but it is not exactly what I am trying to do since I can extend the video but can not make exactly 3 loops.

    



    ffmpeg -ignore_loop 0 -i animated.gif -movflags faststart -pix_fmt yuv420p -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" -t 12 videoloop.mp4


    



    So as you can see I am already able to achieve what I want, but with 2 shell commands :

    



    ffmpeg -i animated.gif -movflags faststart -pix_fmt yuv420p -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" video.mp4
ffmpeg -f concat -safe 0 -i <(printf "file '$PWD/video.mp4'\n%.0s" {1..3}) -c copy videoloop.mp4


    



    Is it possible to do this with only one call to ffmpeg ?

    



    I tried with -loop option for the input file. It doesn't work for gifs. I also tried with -stream_loop. It creates something corrupted.

    


  • converting a UYVY FFmpeg

    19 février 2013, par Engine

    I want to read and show a video using opencv. I've recorded with Direct-show, the Video has UYVY (4:2:2) codec, since opencv can't read that format, I want to convert the codec to an RGB color model, I readed about ffmpeg and I want to know if it's possible to get this done with it ? if not if you a suggestion I'll be thankful.

    lavfi/dnn : Async Support for TensorFlow Backend

    This commit enables async execution in the TensorFlow backend
    
and adds function to flush extra frames.
    

    The async execution mechanism executes the TFInferRequests on
    
a separate thread which is joined before the next execution of
    
same TFRequestItem/while freeing the model.
    

    The following is the comparison of this mechanism with the existing
    
sync mechanism on TensorFlow C API 2.5 CPU variant.
    

    Async Mode : 4m32.846s
    
Sync Mode : 5m17.582s
    

    The above was performed on super resolution filter using SRCNN model.
