[xiph-commits] r12903 - trunk/theora/lib/dec

[giles at svn.xiph.org]

Author: giles

New Revision: 12903

Modified:
   trunk/theora/lib/dec/decinfo.c
Log:
Loosen the bitstream version checking to match the older code and 
specification: We expect general playback compatibility regardless
of the subminor version, and accept earlier minors under the same
minor as backward-compatible.
