  • Keeping control of your media in your hands

  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • avcodec/mpegvideo_enc : Fix abort on allocation errors

    avcodec/mpegvideo_enc : Fix abort on allocation errors

    mpegvideo_enc uses a fixed-size array of Pictures ; a slot is
    
considered taken if the Picture's AVFrame is set.
    
When an error happens after a slot has been taken, this Picture
    
has typically not been reset and is therefore not usable for
    
future requests. The code aborts when one runs out of slots
    
and this can happen in case of allocation failures.
    
Fix this by always unreferencing a Picture in case of errors.

    hw_base_encode : make recon_frames_ref optional

    Vulkan supports some stupidly odd hardware, that unfortunately,
    
most modern GPUs happen to be.
    
The DPB images for encoders may be required to be preallocated
    
all at once, and rather than be individual frames, be layers of
    
a single frame.
    

    As the hw_base_encode code is written with the thought that either
    
the driver or the device itself supports sane image allocation,
    
Vulkan does not leave us with this option.
    

    So, in the case that the hardware does not support individual
    
frames to be used as DPBs, make the DBP frames context optional,
    
and let the subsystem manage this.

  • FFmpeg change resolution

    15 mars 2012, par Iva

    I have changed resolution video using next code :

    pFrameOut = avcodec_alloc_frame();
    
avpicture_fill((AVPicture *)pFrameOut, video_outbuf, PIX_FMT_YUV420P, video_width_out, video_height_out );          
    
avcodec_decode_video2( pCodecCtx, pFrame, &amp;frameFinished, &amp;packet );                 
    
if(frameFinished)  // Did we get a video frame?
    
{
    

    
    static struct SwsContext *img_convert_ctx_in = NULL;
    
    if (img_convert_ctx_in == NULL)
    
    {
    
        img_convert_ctx_in =sws_getContext( pCodecCtx->width, pCodecCtx->height, pCodecCtx->pix_fmt,video_width_out, video_height_out, PIX_FMT_YUV420P, SWS_BICUBIC,NULL, NULL, NULL );             
    
        if (img_convert_ctx_in == NULL)
    
        {
    
            LOGI(10,"naInitFile::Could no create Software Scale Context");
    
            return ;
    
        }
    
    }
    

    
    retval = sws_scale(img_convert_ctx_in, pFrame->data, pFrame->linesize, 0, pCodecCtx->height, pFrameOut->data, pFrameOut->linesize);
    
    SaveVideoFrame();
    
}//end  if(frameFinished)  

    But after that time of play increased twofold. Why it could happen ?
