  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Can't download Accord NuGet in VS 2015 nor VS 2017

    26 juin 2017, par John Leone

    Here is the package,,, NuGet Accord.Video.FFMPEG

    Here is the error,,,
    Package restore failed. Rolling back package changes for ’EssentialTimeLapseVideo’.

    I used this NuGet in a Windows Form app I am working on, and had no issues. Then something came up with Time Lapse, and I wanted to use it in a UWP, but, for some reason it won’t install.

    I tried the mirror suggested, and got the following.
    enter image description here

    Any help would be appreciated. Thanks, John.

  • [MPV][FFMPEG] stack two videos to play them synchronously without re-encoding, but with a rotation (from metadata) applied to one of them

    10 juin 2022, par publicIDI

    I have 3 videos with the same resolution (1920x1080), but one of them has the rotation property set in the metadata while the two others are reencoded in the correct orientation.

    


    I would like to stack them horizontally to compare their quality without re-encoding.
I know how to dynamically stack and display them with MPV, but not when one of them has a rotation metadata property :

    


    Two videos in parallel

    


    mpv --lavfi-complex="[vid1][vid2]hstack[vo];[aid1][aid2]amix[ao]" "v1_metadata.mp4" --external-file="v2.mp4"


    


    Three videos in parallel

    


    mpv --lavfi-complex="[vid1][vid2][vid3]hstack=inputs=3[vo];[aid1][aid2][aid3]amix=inputs=3[ao]" "v1_metadata.mp4" --external-files="v2.mp4;v3.mp4"


    


    Precisions

    


    v1_metadata.mp4 : rotation in the metadata

    


    v1_metadata.mp4

    


    v2.mp4, v3.mp4 : no metadata rotation

    


    v2.mp4 and v3.mp4

    


    How can I "apply" the rotation to the first video (v1_metadata.mp4) in order to display it stacked with the others ?

    


    Thanks,

    


  • FFMPEG : Create contiguous videos from webcam

    19 octobre 2015, par Kr0e

    Can FFMPEG record from webcam in (for instance 10 sec.) intervals ?
    I need contiguous small videos from webcam (used for a p2p live streaming app, which I’m developing), so that I can play them one after the after without noticing, that there are actually multiple videos.

    I guess, I have to break on key-frames or something like this, so that I have clear cuts.

    For playing multiple videos without stuttering I use the Web MediaSource API and it does actually work quite well already.

    I only need to segment a webcam stream into multiple variable video files.

    Thanks !
