Support audio et vidéo HTML5
10 avril 2011MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...) -

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 ?
