  • Les statuts des instances de mutualisation

    13 mars 2010, par

    Pour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.
    Les différents statuts possibles sont : prepa (demandé) qui correspond à une instance demandée par un utilisateur. Si le site a déjà été créé par le passé, il est passé en mode désactivé. publie (validé) qui correspond à une instance validée par un (...)

  • Does ffmpeg support clip feature in ass with subtitle filter ?

    14 mars 2019, par neonew

    I want to use clip/iclip feature in ASS with ffmpeg to display the subtitles one by one. Below is my ASS file content :

    ffmpeg command :

    ffmpeg -i input.mp4 -filter_complex "subtitles=myass.ass" output.mp4

    However, the text just appeared two seconds, but didn’t have clip feature.
    So, is there something wrong ?

  • Building FFmpeg for Android

    13 juin 2013, par varevarao

    I've spent almost a week on this now, trying to get FFmpeg "Angel"/"Happiness" to build for Android.
    I've tried build scripts from all over the internet to no avail. I got closest was using this. As the author himself says the script doesn't work for newer versions of FFmpeg due to this bug, which has been dismissed on that ticket saying "I found a Makefile that does it." This was dis-heartening, being the only post on all of the vast Google world that was anywhere close to my problem.
    So, question time :

    Is there a way to get around the above bug ? I'm trying to use the newest ffmpeg API, and "Love" is just giving me "undefined reference" errors while trying to use av_encode_video2(), and av_free_frame(). The code I was working on the lines of is at the ffmpeg git repo, under /doc/examples/decoding_encoding.c (the function starting on line 338).

    Update : So they've done away with codec_names.sh in "Angel". Sorry didn't notice that before, but the problem persists in a different avatar now. With every build attempt the compiler throws a certain

    start ndk-building...
    
/home/<user>/android-ndk/build/core/build-binary.mk:41: *** target file `clean&#39; has both : and :: entries.  Stop.
    
</user>

    Say whatnow !?

  • Not able to configure FFserver for RTSP

    2 novembre 2015, par Sujith

    I am kind of new to the streaming world... so, please forgive me if I ask kind of dumb question.

    I am trying to stream my pre-recorded file over RTSP through FFserver.

    My config file is :

    RTSPPort 8544
    
<feed>
    
    File /home/xyz/tmp/feed2.ffm
    
    FileMaxSize 200K
    
    ACL allow 127.0.0.1
    
</feed>
    

    
<stream>
    
    Feed feed2.ffm
    
    Format rtsp
    
    VideoFrameRate 15
    
    VideoSize 352x240
    
    VideoBitRate 256
    
    VideoBufferSize 40
    
    VideoGopSize 30
    
    AudioBitRate 64
    
    StartSendOnKey
    
</stream>

    After starting the server, it give the below log :

    $ ./ffserver -f doc/ffserver.conf

Wed Sep 19 17:03:32 2012 FFserver started.

    And now from my VLC client I am trying to type the URL : rtsp ://xxx.xxx.xxx.xxx:8554/test.sdp

    But, what happens is that, there is no response on the ffserver.

    I have no clue what might be the problem. Thanks in advance.
