Hello, hard decoding and switching Ist-& GT; Hwaccel_retrieve_data(pFrame, pFrame) after the pFrame why playing directly with the SDL player will show abnormal Ah, conversion through yuv420 has become trouble again. SDL texture created as: SdlText = SDL_CreateText(SDL Render, SDLPIXELFORMAT NV12, SDL_TEXTUREACSS_STREAMING, Screen_w, streen_h); The SDL refresh code should read SDL_UpdateText(sdlText, NULL, pFrame Target-& GT; Data[ 0] , pFrame Target-& GT; Linesize[ 0] ); SDL_RenderCopy(SDL Render, sdlText, NULL, NULL); SDL_RenderPresent(SDL Render);

I am afraid that NV12 usage with SDL is problematic: http://sdl.5483.n7.nabble.com/SDL-UpdateTexture-and-NV12-td48198.html
