[xiph-cvs] cvs commit: theora/examples dump_video.c

  Modified:    examples dump_video.c
  Log:
  Fixed a problem where very small streams would not output anything.
  
  Turns out we were checking for EOF before queueing any pages we already had data for after parsing the headers. If we'd already buffered the whole file, then these pages would never get queued, and thus never decoded.
