    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 on windows 7, encode video in mp4 for HTML 5 video fail

    14 avril 2013, par manonthemoon

    I try to encode my video with FFmpeg, to convert to mp4.
    But the video doesn't work on html 5. I don't understand why.

    I found this command on the web and I tried it :

    ffmpeg.exe -i wildlife.wmv -b 1500k -vpre slow -vpre baseline -vcode libx264 \
      -g 30 wildlife.mp4
    

    But it fails, and I have this error :

    File for preset 'slow' not found

    I check the folder "presets" and the preset is on the folder, so I don't understand why it's telling me this error.
    I tried with the complete path, it fails too.

  • ffmpeg transcoding one input video stream and multiple output video streams in the same file

    28 janvier 2020, par user2165262

    I am trying to transcode a single video file with 1 video stream and several audio streams to the file having same video stream in different bitrates/sizes with correct padding at the same time.

    the command I use is :

        ffmpeg -y -ss 600 -t 600 -i "INPUT.mkv" -map_chapters -1 -map 0:0 -c:v libx264 -keyint_min 48 -g 96 -bufsize 350k -b:v 350k -minrate 300k -maxrate 400k -profile:v baseline -level 3.0 -preset slow -vf "scale=iw*min(480/iw\,272/ih):ih*min(480/iw\,272/ih),pad=480:272 :(480-iw)/2 :(272-ih)/2" -map 0:0 -c:v libx264 -keyint_min 48 -g 96 -bufsize 650k -b:v 650k -minrate 500k -maxrate 800k -profile:v baseline -level 3.1 -preset slow -vf "scale=iw*min(640/iw\,360/ih):ih*min(640/iw\,360/ih),pad=640:360 :(640-iw)/2 :(360-ih)/2" -map 0:1 -c:a libfaac -b:a 32k -ar 44100 -f mpegts OUTPUT.m2ts
    

    ffmpeg creates two video streams, however the bitrate and resolution for all of them are taken from the last video arguments - i.e. both streams are 640x360 :

        Output #0, mpegts, to ’OUTPUT.m2ts’ :
        Stream #0:0(eng) : Video : h264, yuv420p, 640x360 [SAR 559:560 DAR 559:315], q=-1—1, 650 kb/s,     Stream #0:1(eng) : Video : h264, yuv420p, 640x360 [SAR 559:560 DAR 559:315], q=-1—1, 650 kb/s, 90k tbn, 23.98 tbc (default)
        Stream #0:2(rus) : Audio : aac, 44100 Hz, 5.1, s16, 32 kb/s (default)
        Stream mapping :
        Stream #0:0 -> #0:0 (h264 -> libx264)
        Stream #0:0 -> #0:1 (h264 -> libx264)
        Stream #0:1 -> #0:2 (aac -> libfaac)
        Press [q] to stop, [?] for help
    

    Is it practically possible to make transcoding to several bitrates to the same file ?
