  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Copy frame specific properties (eg. width and height)

    5 août 2014, par gkuczera

    It’s not that something is not working, I just can’t figure out how to copy frame props (eg. height and width) after usage of sws_scale function - this function doesn’t copy them into the destination frame).

    Why I need this ? My frame after scaling is becoming the input for the filter, and it’s source props have to be specified to specific numbers, not like it accepts everything (so a frame with width and height equal to zero - which I get after scaling - is not an option).

    I tried to use

    av_frame_copy_props

    but even in this function’s description, they mentioned that it will not do this.

    Here is the code :

    AVFrame* tOwnersFrame = pOwner->getFrame();
    
AVFrame* tResizedFrame = avcodec_alloc_frame();
    
int tResizedFrameWidth = pMaxFrameWidth;
    
int tResizedFrameHeight = pMaxFrameHeight;
    

    
if (!tResizedFrame)
    
{
    
    cout &lt;&lt; "Couldn't allocate the frame!" &lt;&lt; endl;
    
    return;
    
}
    

    
uint8_t* tBuffer;
    
int tBytesNeeded;
    

    
tBytesNeeded = avpicture_get_size(PIX_FMT_RGB24, tResizedFrameWidth, tResizedFrameHeight);
    
tBuffer = (uint8_t*)av_malloc(tBytesNeeded * sizeof(uint8_t));
    
avpicture_fill((AVPicture*)tResizedFrame, tBuffer, PIX_FMT_RGB24, tResizedFrameWidth, tResizedFrameHeight);
    

    
mSwsContext = sws_getCachedContext(mSwsContext, pOwner->getFrameWidth(), pOwner->getFrameHeight(), AV_PIX_FMT_BGR24, tResizedFrameWidth, tResizedFrameHeight, PIX_FMT_RGB24, SWS_BILINEAR, NULL, NULL, NULL);
    
sws_scale(mSwsContext, (const uint8_t* const *)tOwnersFrame->data, tOwnersFrame->linesize, 0, pOwner->getFrameHeight(), tResizedFrame->data, tResizedFrame->linesize);
    
cout &lt;&lt; "FramesMerger::resizeFrameMax - arg frame size: " &lt;&lt; pOwner->getFrame()->width &lt;&lt; ", " &lt;&lt; pOwner->getFrame()->height &lt;&lt; endl;
    
cout &lt;&lt; "FramesMerger::resizeFrameMax - resized frame size: " &lt;&lt; tResizedFrame->width &lt;&lt; ", " &lt;&lt; tResizedFrame->height &lt;&lt; endl;
