  • Qualité du média après traitement

    21 juin 2013, par

    Le bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?
    Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...)

  • OpenCV no longer working after Homebrew install

    28 mars 2014, par Tom smith

    I have have been running OpenCV from QT creator on Mac OSX.
    I was having trouble getting VideoWriter to work so it was suggested I try installing ffmpeg with opencv.
    Using brew I executed this command

    brew install homebrew/science/opencv --with-ffmpeg

    However, during this process I received the following error

    Warning: Could not link opencv. Unlinking...
    
Error: The `brew link` step did not complete successfully
    
The formula built, but is not symlinked into /usr/local
    
You can try again using `brew link opencv'

    The "possible conflicting files were mostly from "/usr/local/include/opencv2/"

    I tried the command brew suggested but this gave me a permission denied warning so I found a fix to execute before the command, both of which are below.

    sudo chown -R `whoami` /usr/local
    
brew link --overwrite opencv

    This appeared to execute correctly giving me the following response

    Linking /usr/local/Cellar/opencv/2.4.8.2... 251 symlinks created

    The problem is this now seems to have broken my working project. When I try to run the project now I get the following errors
    Unfortunately after trying to rebuild the project I cannot get the error below to show up in the terminal again but it said the following error, was expected in /usr/local/include but not found in the build directory (afraid I cannot be sure of the exact wording)

    dyld: lazy symbol binding failed:

    In QT creator however, when trying to build the project it says

    error: symbol(s) not found for architecture x86_64
    
error: linker command failed with exit code 1 (use -v to see invocation)

    Any suggestions for a fix, and also how I can get VideoWriter to work with opencv on Mac OSX after I have my project working again ?

  • What is the structure of AVPacket::data ?

    17 mai 2017, par Sanduni Wickramasinghe

    I’m extracting data of an MPEG data packet using data member variable which is inside AVPacket structure.

    AVDictionary *options = NULL;
    
AVFormatContext *s = avformat_alloc_context();
    
AVPacket *pkt = new AVPacket();

    Now I can read data as a bit stream. But I want to know the structure of data that I am reading. I mean, by separating it in to I,P and B frames.

    int ret = avformat_open_input(&s, url_ref, NULL, NULL);
    

    
data = pkt->data;

  • ffmpeg is not working on live server in PHP

    11 mai 2017, par thakur

    I have downloaded the ffmpeg package and set the path of usr/bin of ffmpeg .By this ffmpeg is running on the localhost correctly as shell_exec('ffmpeg -versoin');, but when I run the same code on live server ffmpeg is not working.

    I have also set the correct directory path for live server. The problem is all other commands is running correctly on live server except ffmpeg.
