  • (Dés)Activation de fonctionnalités (plugins)

    18 février 2011, par

    Pour gérer l’ajout et la suppression de fonctionnalités supplémentaires (ou plugins), MediaSPIP utilise à partir de la version 0.2 SVP.
    SVP permet l’activation facile de plugins depuis l’espace de configuration de MediaSPIP.
    Pour y accéder, il suffit de se rendre dans l’espace de configuration puis de se rendre sur la page "Gestion des plugins".
    MediaSPIP est fourni par défaut avec l’ensemble des plugins dits "compatibles", ils ont été testés et intégrés afin de fonctionner parfaitement avec chaque (...)

  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • ffmpeg - convert image sequence to video with reversed order [closed]

    12 août, par 0__

    Looking at the docs, it is not apparent to me whether ffmpeg would allow me to convert an image sequence to a video in reverse order, for example using this sequence :

    



    frame-1000.jpg
frame-999.jpg
frame-998.jpg
...
frame-1.jpg


    



    Is it possible to give a "step direction" for the frame indices ?

    


  • ffmpeg livestream alway stop after 160hours streamming

    2 avril 2018, par JerryJumper88

    I use ffmpeg with this code to run stream youtube 24/7 from Windows VPS. But stream alway stop after 160-167 hours and I don’t know why.

       dir/b/s "C:\Users\NASA\Desktop\ffmpeg\bin\1\*.mp4" > list.txt
    
:encode video
    
:loop
    
for /F "delims=;" %%F in (list.txt)  DO ffmpeg -re -i "%%F" -vcodec libx264 -preset veryfast -maxrate 2500k -bufsize 3368k -vf "format=yuv420p" -g 60 -acodec libmp3lame -b:a 198k -ar 44100 -metadata title="" -metadata artist="" -metadata album_artist="" -metadata album="" -metadata date="" -metadata track="" -metadata genre="" -metadata publisher="" -metadata encoded_by="" -metadata copyright="" -metadata composer="" -metadata performer="" -metadata TIT1="" -metadata TIT3="" -metadata disc="" -metadata TKEY="" -metadata TBPM="" -metadata language="eng" -metadata encoder="" -f flv -s 1280x720 rtmp://a.rtmp.youtube.com/live2/xxxx-xxxx-xxxx-xxxx
    
goto loop

    And this is stream log. I google " Larger timestamp than 24-bit : 0xffffff9f" but nothing about this error. I contacted to admin server system, he comfirmed that has no issue connection. Then I tried again in Windows 7 and Windows server 2012, same result, still drop after 160h on youtube.

  • how do I set speed rate (ex:double speed) in FFmpeg library ?

    19 avril 2018, par geeeek

    I’m working on rtsp live video from ffmpeg and rendering it on the screen.

    However, the image is displayed after 1 to 2 seconds.

    to reduce video delay, So I want to increase the playback speed in my program.

    int64_t duration = m_formatCtx-> duration;
    
duration = duration * 1000;
    
av_seek_frame (m_formatCtx, m_videoStream, duration, AVSEEK_FLAG_ANY);
    
av_seek_frame (m_formatCtx, m_audioStream, duration, AVSEEK_FLAG_ANY);
    
while (av_read_frame (m_formatCtx, & m_packet)> = 0)

    I can not get the result I want in this way.
