MJPEG Tools Svn

turn off iframe only for vcd format

Never converted properly from a standalone app to being integrated into cvs

if/when mjpegtools-config.h is actually needed it can be revived.

oooooooooooooooooops

- add 1 to mmx version as found by Stephen Beahm:

Both the C-reference and altivec versions of bsumsq_sub22_mmx() implement the
following:
v = ((p1f[i]+p1b[i]+1)>>1) - p2[i];

The mmx version does not add the one (+1).

- make twos[] static, so it doesn't have to be pushed on the stack everytime the function sumsq_mmx() is called

Stephen Beahm noticed that the mmx code had not been updated like the
C-reference and Altivec code had been (2003/10)

free() getting a bogus pointer because simd_env is modified by parse_next.
Another fine patch submitted by Stephen Beahm ;)

Missing emms() spotted by Stephen Beahm - thanks!

Couple missing '-' to turn multithread into multi-thread (so it matches the
mpeg2enc program usage).

Fix obscure threading issue due to the last frame being read
while the corresponding StreamState is being set.
