Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

SDL2 C++ Capturing Video of Renderer Animation/Sprite
27 octobre 2016, par alokI have an animation/sprite created using SDL2. The animation works fine when it is being rendered to a screen. But now I also want it to be recorded into a video file (locally stored). For this, I am planning on using FFmpeg APIs, to which I’ll be sending a raw RGB pixel data array.
My problem is with fetching the data from SDL2 APIs.
What I’ve tried is :
// From http://stackoverflow.com/questions/30157164/sdl-saving-window-as-bmp
SDL_Surface *sshot = SDL_CreateRGBSurface(0, 750, 750, 32, 0x00ff0000, 0x0000ff00, 0x000000ff, 0xff000000);
SDL_RenderReadPixels(gRenderer, NULL, SDL_PIXELFORMAT_ARGB8888, sshot->pixels, sshot->pitch);
// From https://wiki.libsdl.org/SDL_RWFromMem
char fName[50];
sprintf(fName, "/tmp/a/ss%03d.bmp", fileCnt);
char bitmap[310000];
SDL_RWops *rw = SDL_RWFromMem(bitmap, sizeof(bitmap));
SDL_SaveBMP_RW(sshot, rw, 1);Above does not work. But dumping a single frame into a file with following code works :
SDL_SaveBMP(sshot, "/tmp/alok1/ss.bmp")
This obviously is not an acceptable solution - Writing to thousands of BMPs and then using FFmpeg from command-line to create a video.
What am I doing wrong ? How do you extract data from SDL_RWops ? Is the use of SDL_RWFromMem the right approach to my problem statement ?
