  • 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" (...)

  • FFmpeg Single Input, Seek to Multiple Outputs

    2 avril 2020, par shesharp

    I'm trying to get multiple snapshots of a single input file using Input Seeking.
I want to seek to different keyframes and save each to different output images.

    



    I can use this using multiple calls :

    



    ffmpeg -ss 280 -i sample.mp4 -aspect 1.7777777777778 -vframes 1 -qmax 9 -qmin 8 -bt 10000000 -y -pix_fmt yuv420p out1.jpg
ffmpeg -ss 300 -i sample.mp4 -aspect 1.7777777777778 -vframes 1 -qmax 9 -qmin 8 -bt 10000000 -y -pix_fmt yuv420p out2.jpg
ffmpeg -ss 302 -i sample.mp4 -aspect 1.7777777777778 -vframes 1 -qmax 9 -qmin 8 -bt 10000000 -y -pix_fmt yuv420p out3.jpg


    



    Unfortunately I have to call ffmpeg programmatically using exec. Is there a way to batch process the tasks above ? It has to use input seeking. Thanks.

    


  • avformat/matroskaenc : Avoid seek when writing Cues at the front

    avformat/matroskaenc : Avoid seek when writing Cues at the front

    When the Cues are written in front of the Cluster, the muxer would seek
    
to the beginning (to where the Cues ought to be written) and write the
    
Cues ; afterwards it would seek back to the end of the file only to seek
    
to the beginning once again to update several elements there. This
    
commit removes the seek to the end.

  • ffmpeg : how to extract 1st video, english audio and french subtitle from video file in one command line ?

    15 mai 2020, par Sxilderik

    I have read many posts related to extracting streams per language with ffmpeg, but it seems that the -map 0:m:language:xxx is global, and goes for all streams.

    &#xA;&#xA;

    Let’s say I have a video file that contains hopefully one english audio stream and some french subtitle streams, among possibly many other streams. I want to get a smaller file with the first video track, the (first) english audio stream and all the french subtitle streams.

    &#xA;&#xA;

    If I run

    &#xA;&#xA;

    ffmpeg -i "$file" -map 0:v:0 -vcodec copy -map 0:m:language:eng -acodec copy -map 0:m:language:fre -scodec copy -f matroska "${file%.*}.mkv_out"&#xA;

    &#xA;&#xA;

    I get in file.mkv_out all audio and subtitle tracks which are either french or english.

    &#xA;&#xA;

    Is there a way to achieve this, without having any prior knowledge of track numbers in the original file ?

    &#xA;&#xA;

    Thanks.
