  • 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) (...)

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.

  • 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 (...)

  • FFMPEG and -crf on Android

    12 juin 2014, par mister-viper

    yesterday I managed to build a newer Version of FFMPEG for Android. I directly created a binary which allows me to invoke commands per commandline. I builded the Version using NDK r9d and the 4.8 linux_x86_x64 toolchain.

    After including everything in my Application my goal was to execute the command for which I did the whole effort.

    My goal is to run :

    ffmpeg -i example.mp4 -r 30 -vcodec libx264 -crf 0 output.mp4

    Running this command on the command line via python works absolutly fine. However, running this command on Android does not work.

    1) I get the error that I have to add

    -strict experimental

    After reading FFMPEG docu I found out, that this is due to the libx264. However, I do not understand why I have not to add this comment in the Python version.

    2) After adding the parameter above, I was able to convert the video. However, the result was horrible. The transcoded images were just some noisy blinking green stuff. Thus, I looked for the problem. The problem is the parameter :

    -crf 0

    Due to this parameter, the result was so horrible. However, if I change the parameter to

    -crf 1

    everything is working as expected. BUT : I really want a lossless encoding here. That was the reason for choosing -crf 0. Moreover, this parameter works fine in my python version.

    Can anybody explain to me :
    1) What are I’m doing wrong ?
    2) How can I use -crf 0 on Android ?

    Best regards,
    André

    I’ve tried adding sleep(5) after :

            exec($cmd, $out, $ret);

    to give the script time to move the moov atom to the front before uploading the local file to s3 and then deleting the local file, but it is not 100% reliable.

    Any ideas ?
