  • Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs

    12 avril 2011, par

    La manière la plus simple d’ajouter des informations aux auteurs est d’installer le plugin Inscription3. Il permet également de modifier certains comportements liés aux utilisateurs (référez-vous à sa documentation pour plus d’informations).
    Il est également possible d’ajouter des champs aux auteurs en installant les plugins champs extras 2 et Interface pour champs extras.

  • x264 encoder with JNA

    17 mai 2014, par baba

    I have been busy creating a JNA wrapper around x264.dll. I have the following class for my x264_param_t :

    http://pastebin.com/Mh4JkVpP

    However, when I try to initialize my x264_param_t like that

    x264_param_t param_t = new x264_param_t;

    I get the following error :

    Exception in thread "main" java.lang.IllegalArgumentException: Can't determine size of nested structure: Can't instantiate class anotherReversed.x264_param_t$Vui (java.lang.InstantiationException: anotherReversed.x264_param_t$Vui)
    
        at com.sun.jna.Structure.calculateSize(Structure.java:790)
    
        at com.sun.jna.Structure.allocateMemory(Structure.java:287)
    
        at com.sun.jna.Structure.<init>(Structure.java:177)

        at com.sun.jna.Structure.<init>(Structure.java:154)
    
        at anotherReversed.x264_param_t.<init>(x264_param_t.java:7)
    
</init></init></init></init></init>

    If I comment out the Vui in it’s parent class constructor, the instantiation is ok. I wonder what is different with EXACTLY this nested structure, as there are 2 others (namely Rc and Analyse ) that are nested in the same way. Somehow, though, JNA isn’t able to find the required size for Vui. Any pointers ?

    Edit :
    It seems that all the other nested structs (analyse and rc ) were also not initialized. I wonder why ?

  • How to seek in FFmpeg C/C++

    21 mars 2016, par DRiFTy

    Does anyone know how to implement seeking by seconds (or milliseconds) in FFmpeg. I currently have a loop running through the frames of a video using av_read_frame() and I want to determine what time this frame should be at in seconds. If it gets to a certain point then I want to seek to a later point in the video. By the way it is not a video player, just processing the frames. Ive heard I should be able to get the dts or pts from the packet but its always returning 0.

  • Flash Media Server Recording Delay

    14 novembre 2011, par Corey

    I have an application where a user can record themselves singing along to a song. Once I receive the NetStream status event 'Record.Start' I start playing an audio file. Once the audio completes, I stop recording. Next, I have a script that runs FFMPEG to combine the recorded video/audio with the same music file. The problem I'm finding is that there is a noticeable delay between the recorded audio and the music. It seems also that this delay depends on network speed as it varies depending on the network. Can I determine this delay through the FMS dynamically ?
