The parser for the outdef will accept a negative value for the first
named channel's gain. As negative values effectively only invert the
phase of the signal, and not negate the level, the gains' absolute
values must be used to correctly accumulate the levels.

Expands the parser to also accept the separator '-' in addition to
'+', and take the negative sign into consideration.

While trying to use pan to subtract two channels (actually to see whether a
two-channel file I have is effectively mono), I noticed that
"pan=mono|c0=-0.5*c0+0.5*c1" would work, while "pan=mono|c0=0.5*c0-0.5*c1"
would cause the parser to choke, expecting a '+'.
Using this (second) patch, you

movd is SSE2. Can be worked around by moving it through the stack though.

Using lfg was an overkill in this case where the random numbers
were only used for encoder descisions. Should increase result
uniformity between different FPUs and gives a slight speedup.

Should improve encoding performance a bit with twoloop and alot with the
fast coder.

Hi!
Attached patch removes a warning that is always shown if the
default mxf muxer is used.
