adb98a3d22 VC1: restore optimizations broken in 9a1ced32. 
They were moved into code under HAVE_YASM and most of them
even into completely disabled code with no reason given
for that in the commit message.

73ad4471a4 rv34: Handle only complete frames in frame-mt. 
Correct handling of errors to prevent hags or crashes is very complex

The frame initializing is also moved from decode_slice() to
decode_frame() for clarity.
