    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) (...)

  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • ffmpeg combining audio tracks on copy

    22 janvier 2024, par janeden

    I tried to copy all streams (video, audio, subtitle) and add a tag with the following command in order to play the files using QuickTime player :

    


    ffmpeg -i in.mp4 -vcodec copy -tag:v hvc1 -acodec copy -scodec copy -map 0 out.mp4


    


    The resulting file does open with QuickTime player, and the video/subtitles play fine, but the two audio tracks (E-AC3 in English and German) from the input file cannot be selected (View → Languages → None) and are in fact merged into each other while playing the video, even though both tracks are shown separately in Inspector → Audio Details and VLC handles them correctly. Is this a bug in QuickTime player, or would I need to add another option for QuickTime ?

    


  • What command convert mjpeg IP camera streaming to mp4 file with lowest CPU usage ?

    23 septembre 2015, par ChanhLM

    like above question, I want find out what ffmpeg command can help me reduce cpu usage when running 50 IP camera (running same 50 command).

    My ffmpeg command :

    ffmpeg  -f mjpeg -y -use_wallclock_as_timestamps 1 -i 'http://x.x.x.x:8090/test1?.mjpg' -r 3 -reconnect 1 -loglevel 16 -c:v mjpeg -an -qscale 10 -copyts '1.mp4'

    50 command like that take my computer (4 core) 200% CPU

    I want this computer can run for 150 camera, any advise ?

    =========================================================

    using -c:v copy can make it faster but fize size is terrible

    I try slow down frame rate by 3 with -r 3 or -framerate 3 to decrease file size but not succesful (because vcodec copy can’t do that).

    Have any option to force input frame rate by 3 ?

    (sorry for my bad English)
