  • 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 (...)

  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • Streaming videos in multiple-bitrates without manually creating video files in each bitrate

    5 janvier 2014, par M.Yazdian

    I want to have a media file that I can stream at multiple bitrates using FFMPEG (for encoding and multiple bitrate generation) and Flash Media Server (for streaming).

    In "LIVE BROADCASTING" ffmpeg made multiple bitrate videos from a single bitrate source but there were no files for the different bitrates. A file would be created for different bitrates when a viewer requested that bitrate streaming video but when a request was terminated the generated file was deleted.

    So I searched in Flash Media Server and found (hds-vod), but in hds-vod I should create one file for every bitrate, for example if I have 2000 videos in my archive with HD quality (1024 kbps) I should make 4 videos with different bitrates from one video and together I have created 10,000 videos.

    So to have 2000 videos in five bitrates (1024k, 760k, 320k, 145k, 64k), and now I have 10,000 videos. I have space for 2000 videos and I don't have free space in my server for 10,000 video files.

    I want to stream "ON-DEMAND" videos in my server and not have the different bitrate files be continually generated like this.

    Does anyone have any advice ?

    Thank you

  • MPEG4 videos cannot be played on iOS14 (AVPlayer issue)

    28 septembre 2020, par vanste25

    I have a piece of code that uses ffmpeg with default mpeg4 codec to merge multiple videos and audio songs.

    


    ffmpeg -i input1.mp4 -i input2.mp4 -filter_complex "concat=n=2:v=1:a=1" -f MOV -vn -y output.mp4


    


    Everything worked on iOS13 and after the update to iOS14, videos are black and cannot be played by any player. Sound is there and it's good.
I tried to switch to h264 and it works good, but as you already know, h264 is under GPL and it is expensive and requires code to be open sourced which is not acceptable for me.

    


    None of the mpeg4 videos can be played in AVPlayer.

    


    What was changed ? Anything in release notes ?
Is that a bug ? Or a feature ?

    


    Thanks

    


  • ffmpeg generate encoded sequence of videos from playlist

    20 janvier 2018, par Massimo Vantaggio

    i use ffmpeg to encode my videos to be ready for mpeg dash process :

    ffmpeg -y -i legend.mp4 -c:a copy -c:v libx264 -x264opts 'keyint=48:min-keyint=48:no-scenecut' -r 24 -b:v 1500k -maxrate 1500k -bufsize 1000k -vf "scale=-1:816" out.mp4

    This command line work fine, and i wonder to know how to create a mp4 encoded file like above from a sequence of videos ?
    I try to get a faster process, and i think that i don’t need to encode separately all videos and after create a sequence (a big video) with post production software.. I wish to resolve all by a sigle command line,
    Is there a way to give a playlist for input to get only one output video within the sequence of the playlist all with the same encoding assuming that all videos have same frame rate and same resolution ?
    Thanks,
    Dan
