    configure : Silence EMMS warnings in ICC

    Real world MMX code does not put EMMS at the start and end of every function,
    
it would be incredibly inefficient to do that
    
thus do not warn about that

  • Fast green screen video processing on android device

    17 mars 2015, par Si-N

    I have written an app in iOS that takes two video sources, one with moving character on a green screen and any other video. The program then uses the GPUImage framework to add a chroma key shader via OpenGL ES 2 and then merges each frame (so the bottom frame now shows where the green pixels are) and outputs to a new video file. This happens very quickly, faster than real time.

    I have now been tasked with porting the app to Android. I thought it would be fairly straightforward. After doing some research I think I am wrong. There is an Android port of GPUImage but it does not handle video at the moment. I have done some research and come up with a very basic idea.

    I was wondering if you think this approach is feasible :

    Convert one video file to match resolution and type of other video using ffmpeg or JavaCV wrappers.

    Read frame by frame of each video using ffmpeg as MediaMetadataRetriever is very slow and convert into some RGB format. Use shader to apply chroma key effect so both frames are merged.

    Use ffmpeg to output result to a new file.

    This sounds slow, but if it sounds feasible I will try it out. I am not at all sure about making sure the 2 video resolutions / bitrate etc match. One video will be fixed at 1280 * 720 and the other video source will come from the camera on the device so will be variable. Also I think ffmpeg means using NDK which is a whole world of pain I wanted to avoid.

    I have a headache thinking about it. Any advice would be greatly appreciated.

  • Anomalie #2915 : dans privé en colonne gauche dans h3, chevauchement texte sur lien "plus d’info"

    4 mai 2015, par chan kalan

    Je viens de mettre une vue d’écran un peu plus tôt (https://core.spip.net/attachments/download/717/Capture%20d_%C3%A9cran%202015-05-03%20%C3%A0%2023.14.12.png) , au même endroit que toi en page accueil de l’espace privé (et mes exemples précédents se sont perdus depuis 2 ans... désolé), tu peux essayer avec un texte un peu différent, ou en reprenant le même que moi si tu veux, même si ça peut changer en fonction des typographies, je sais pas... Quoi qu’il en soit, l’image n’est pas flottante, elle est en positionnée en absolu, donc c’est bien normal que le texte se superpose.
