c - SDL2.0 Alternative for SDL_Overlay -

so i've been trying go through following tutorial on ffmpeg: http://dranger.com/ffmpeg/tutorial02.html

however, when try compile using gcc, following output:

root:/users/mbrodeur/downloads/hackathon content/tutorials-> gcc -o tutorial02 tutorial02.c -lavutil -lavformat -lavcodec -lz -lavutil -lm -lswscale -d_thread_safe -lsdl2 tutorial02.c: in function ‘main’: tutorial02.c:41: error: ‘sdl_overlay’ undeclared (first use in function) tutorial02.c:41: error: (each undeclared identifier reported once tutorial02.c:41: error: each function appears in.) tutorial02.c:41: error: ‘bmp’ undeclared (first use in function) tutorial02.c:98: warning: assignment makes pointer integer without cast tutorial02.c:110: error: ‘sdl_yv12_overlay’ undeclared (first use in function) 

now, read sdl_overlay no longer used in sdl2, therein lies problem. i've been poking around, can't seem find helpful. there replacement sdl_overlay? necessary?

sdl_overlay used in following context:

sdl_overlay     *bmp; bmp = sdl_createyuvoverlay(pcodecctx->width, pcodecctx->height,                        sdl_yv12_overlay, screen); 

try sdl_createtexture() yuv pixel format matches layout , planar-ity of decoded frames.

or use libswscale convert ffmpeg's yuv buffers rgb.

edit: sdl2 >= 2.0.1 has sdl_updateyuvtexture() updating planar yuv textures don't have manually coalesce libav's buffers more.
