This does not seem to have an effect currently. Fate-h264 passes with
THREADS=1..16 and both threading types as before. It fixes however a
segfault during error resilience with my adaptive-frame-mt patchset.
A picture in use during error resilience gets realloced in another
thread in the fuzzed sample sample_varPAR.avi_s226019.

Fixes segfault in the fuzzed sample bipbop234.ts_s226407.

Same calculation as for RGBA etc to create unpremultiplied output.
Useful for creating an intermediate "Mix/Effects bank", in vision mixer
(switcher) terminology.

Example command:

ffmpeg -i input.mov -vf
"[in]scale=iw:ih:interl=1,format=yuv420p[bg];movie=BBC_blocks_watermark.png,scale=iw:ih:interl=1,format=yuva420p[dog];movie=Kickabout_strap.mov,scale=iw:ih:interl=1,format=yuva420p[strap];[strap][dog]overlay=0:0[me1];[bg][me1]overlay=0:0,scale=0:0:interl=1[out]"
-b:v 3M -an output.mov

Should fix compilation on native windows
We could also use _access() and literal numbers as flags but i cant test it
and the compilation failure should be fixed ASAP

When the extra rear channel is present but unused, the
s->channel_order_tab[] value for that channel is -1. The QMF can be
skipped for the extra channel, and doing so avoids an out-of-array read
on s->samples_chanptr[].

This should work on windows, but if not please contact me ASAP
i have another idea on how to solve this without access() if that
really doesnt work on windows.
