vlc/include/video_output.h
Sam Hocevar b29f85e06c * ./src/video_output/video_output.c: fixed a vout4 image starvation bug. 
* ./plugins/dvd/dvd.c: we look for libdvdcss.so.2 as well as -.so.1.
  * ./configure.in: BSD/OS fixes thanks to Steven M. Schultz.
  * ./Makefile: renamed the `snapshot' rule to `dist'.
  * ./Makefile: removed the `snapshot-nocss' rule which isn't needed anymore.
