  • 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" (...)

  • How to prescale a frame using ffmpeg and H.265

    20 juillet 2017, par akw

    I want to decode video frames with the H.265 coded (AV_CODEC_ID_HEVC)
    I use the following code :

    AVCodec *hevcCodec = avcodec_find_decoder(AV_CODEC_ID_HEVC);
    
AVCodecContext *avctx  = avcodec_alloc_context3(hevcCodec);
    
avcodec_open2(avctx, hevcCodec, 0);
    
AVFrame *frame = av_frame_alloc();
    
AVPacket pkt;
    
av_init_packet(&pkt);
    
pkt.data = myDataPtr;
    
pkt.size = myDataSize;
    
int got_frame = 0;
    
avcodec_send_packet(avctx, &pkt);
    
if (avcodec_receive_frame(avctx, frame) >=0 ) {
    
        got_frame = 1;
    
        ...
    
}

    This works fine, I got my YUV frame and can process it further (like converting to RGB or scaling, etc.)
    However, I would like to somehow tell the ffmpeg library, to scale the AVFrame while decoding (a scale factor of a power of 2 would be sufficient).
    I don’t want to scale after converting to RGB or use swscale or anything. I have to decode a lot of frames and need a smaller resolution.

    Is it possible to give the AVCodecContext some hints to scale the frames ?
    (I tried setting avctx.width and avctx.height, but this did not help)

    avfilter/af_headphone : Remove pointless additions

    buffer_length is a power-of-two and modulo is buffer_length - 1, so that
    
buffer_length & modulo is zero.
