some additional notes;
make sure you use a proper shell (command.com won't work!);
i.e. use cygwin's shell 'sh.exe', then you can combine 1) and 2) into
sh.exe -c './jpeg2yuv-20010113.exe -n 1 -f 25 -I p -j still.jpeg |
./mpeg2enc-pth-20010113.exe -T 160 -f 7 -o still.m2v'
this also keeps you from generating big temporary .yuv files...
another thing, you should use the mpeg2enc-pth-nosse executable, as SSE
support is broken on win32 it seems...
