  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • Encoding and processing into web-friendly formats

    MediaSPIP automatically converts uploaded files to internet-compatible formats.

  • FFPMEG : stream local file to UDP address, make client aware about video length and current frame time offset (make stream seekable ?)

    10 décembre 2014, par klim

    Just started to use FFMPEG. This is a really great library which is capable of video life transcoding and streaming.

    I use following commands to transcode and stream local video file to UDP address :
    ffmpeg -y -re -i inputvideo.mpeg2 -vsync 1 -vcodec mpeg4 -b 1600k -r 15 -crf 20 -acodec aac -ar 44100 -strict -2 -f mpegts udp ://192.168.1.30:1234

    It works smooth. I can open this udp address in VLC player and play life stream.

    Does anybody know how to make client aware about video duration and current time stamp ?

    Ideally would be nice to make stream seekable, as far as I understand it is not possible, but at least I would like to tell VLC client the total duration of the video and current frame time stamp, so it could show the progress.

    Thanks.

  • How to use SDL libraries in the Android project built using ffmpeg

    25 mai 2012, par Harish

    I have built ffmpeg for Android on Ubuntu and used these libraries in an Android project through JNI. But using this I could only use the avcodec & avformat APIs and I read that I need to use SDL libs to display the video file.

    I have installed SDL (.configure, make & make install) and specified the .so file in my Android.mk file

    (LOCAL_LDLIBS := -llog -ljnigraphics -lz -lm $(LOCAL_PATH)/ffmpeg-0.8/android/armv7-a/libffmpeg.so $(LOCAL_PATH)/ffmpeg-0.8/android/armv7-a/libSDL.so)

    as I was getting "undefined reference to" errors.

    But now it complains that /jni/ffmpeg-0.8/android/armv7-a/libSDL.so : could not read symbols : File in wrong format.

    I am not sure if I haven't built the libraries correctly or I haven't specified the correct library in the JNI make file.
