- Hardware YUV overlay (SDL) with real colors ;p It may suck for non

    4:2:0 streams.
  - Removed vout code found in intf file to support fullscreen switching.
    Now only vout_SDL updates SDL data and intf only switch flags such as
    b_reopen_display and b_fullscreen in p_vout->p_sys.
  - Fixed a var name typo in input_programs.c which prevents vlc from
    compiling with --enable-debug option. (i_es_pid -> i_es_id :)

There's a segfault in the termination process due to sdl, I don't really
know what is the problem and I have to work today. Help me!

Good night suckers. I love you too :p

ChangeLog

 0.1.99j:
 
+  * Added hardware YUV overlay support (SDL). Huge performance
+    increase.
   * Minor changes in the Debian files.
   * Fixed fps display.
   * Fixed MPEG1 video decoding. We don't read MPEG 1 PS files for the
