• SDL2.0 Alternative for SDL_Overlay

  2 février 2017, par Josh

  So I’ve been trying to go through the following tutorial on ffmpeg : http://dranger.com/ffmpeg/tutorial02.html

  However, when I try to compile using gcc, I get the 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 this function)
  
  tutorial02.c:41: error: (Each undeclared identifier is reported only once
  
  tutorial02.c:41: error: for each function it appears in.)
  
  tutorial02.c:41: error: ‘bmp’ undeclared (first use in this function)
  
  tutorial02.c:98: warning: assignment makes pointer from integer without a cast
  
  tutorial02.c:110: error: ‘SDL_YV12_OVERLAY’ undeclared (first use in this function)

  Now, I read that SDL_Overlay is no longer used in SDL2, so therein lies the problem. I’ve been poking around, but can’t seem to find anything helpful. Is there a replacement for SDL_Overlay ? Is it necessary ?

  SDL_Overlay is used in the following context :

  SDL_Overlay     *bmp;
  
  bmp = SDL_CreateYUVOverlay(pCodecCtx->width, pCodecCtx->height,
  
                         SDL_YV12_OVERLAY, screen);

• avformat/AVFormatContext : Move fields down to match the fork

  9 juillet 2013, par Michael Niedermayer

  avformat/AVFormatContext : Move fields down to match the fork
  avconv uses private and internal fields from libavformat, we thus must
  
  match the layout even of the fields marked non public.
  
  Otherwise ffmpegs libavformat could not be used as a dropin replacement
  
  on debian/ubuntu
  The current soname of libavformat was not part of any release nor are any
  
  fields marked public moved thus in theory
  
  no installed shared lib ABI breakage should occur. Still the need for this
  
  change is unfortunate and chilling.
  
  If you installed shared libs from a recent development version of libavformat
  
  that is more recent than the last release. You probably want to check or rebuild
  
  applications that linked to it.
  minor versions of avformat & avdevice are bumped to allow detecting this
  
  as both use the updated struct

• Remove avserver.

  9 juin 2014, par Anton Khirnov

  Remove avserver.
  It has not been properly maintained for years and there is little hope
  
  of that changing in the future.
  
  It appears simpler to write a new replacement from scratch than
  
  unbreaking it.
