  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

    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.

  • libavcodec avcodec_open2 returns -22

    28 juillet 2012, par buchtak

    I am trying to learn how to encode video using libavcodec library. I use the following initialization :

    avcodec_register_all();
    

    
// This works fine.
    
AVCodec *avcodec = avcodec_find_encoder( CODEC_ID_H264 );
    

    
AVCodecContext *avctx = avcodec_alloc_context3( avcodec );
    
avctx->bit_rate      = 400000;
    
avctx->width         = 640;
    
avctx->height        = 480;
    
avctx->time_base.den = 15;
    
avctx->time_base.num = 1;
    
avctx->gop_size      = 10;
    
avctx->max_b_frames  = 1;
    
avctx->pix_fmt       = PIX_FMT_YUV420P;
    
av_opt_set( avctx->priv_data, "preset", "slow", 0 );
    

    
// ret should be zero, but it's negative
    
int ret = avcodec_open2( avctx, avcodec, NULL );

    However, avcodec_open2(...) always returns a negative value. The avcodec_find_encoder(...) works fine and the returned pointer is not NULL. I use Win7 x64, 64-bit Zeranoe FFmpeg build from

    http://ffmpeg.zeranoe.com/builds/

    According to the readme the FFmpeg version is 2012-06-22 git-c17808c built with --enable-libx264. I also tried CODEC_ID_MPEG1VIDEO and changing some of the initialization parameters, but no matter what I do, the avcodec_open2(...) always returns value -22. The decoding/encoding example provided with the Zeranoe build (it's the same one as http://ffmpeg.org/doxygen/trunk/api-example_8c-source.html) does not work either...
