  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Streaming video from an image using FFMPEG on Windows

    26 mai 2013, par Daniel Zohar

    I wrote a program that simulates a camera and converts the output into a video stream. The program is required to be able to run on Windows.
    There are two components in the system :

    1. Camera Simulator. A C++ program that simulates the camera. It copies a pre-generated frame (i.e. PNG file) every 0.1 seconds, using the windows copy command, to a destination path ./target/target_image.png
    2. Video Stream. Using FFmpeg, it creates a video stream out of the copied images. FFmpeg is ran with the following command :
      ffmpeg -loop 1 -i ./target/target_image.png -r 10 -vcodec mpeg4 -f mpegts udp://127.0.0.1:1234

    When running the whole thing together, it works fine for a few seconds until the ffmpeg halts. Here is a log while running in debug mode :

    It seems to me there's some kind of collision between the reading and writing to/from the same file. What's also interesting is that on Linux (while replacing the copy with cp) the program works just fine.

    Can someone suggest a way to solve this issue ? Alternatives solutions are also acceptable as long as the logical workflow remains the same.

  • FFMPEG : i need audio channels 7 & 8 to be the main audio track for a video

    10 avril 2013, par lo_fye

    I have a video with 8 channels of audio.

    I need tracks 7 (Left Stereo) and 8 (Right Stereo) to be the audio for the video (which I'm converting to flv).

    I've tried playing with -filter_complex and the join, amix, and amerge filters, as well as the -map parameter, but I can't seem to find the right combination of values :-/

    Output :

    /usr/local/bin/ffmpeg-1.0/bin/ffmpeg -i '/folder/video_name.mov' -f 'flv' \
    
-s '320x240' -b '250k' -aspect '4:3' -ac 1 -ab '64k' -ar '22050' -y \

  • Using FFMPEG to reliably convert videos to mp4 for iphone/ipod and flash players

    23 avril 2016, par Jake Stevenson

    I need to convert videos for use in both a flash player and the iphone/ipod touch. I’m using the following batch script with ffmpeg :

    @echo off
    
ffmpeg.exe -i %1 -s qvga -acodec libfaac -ar 22050 -ab 128k -vcodec libx264 -threads 0 -f ipod %2

    This always outputs an mp4 file, and I can always play it on my PC. The videos also seem to play fine on my iphone 3GS. But with some input files it won’t work for older iphone versions (3G and iPod touch).

    Here’s the ffmpeg output from one such file :

    D:\ffmpeg>encode.bat d:\temp\recording.flv d:\temp\out.m4v

    My suspicion is that it has something to do with the audio encoding. If so, does anyone know how to force it to reencode the audio to the proper format ?

    Any other ideas ?
