hello,
just wanted to let you know, that I've been to build some tools under
cygwin (win32), required to make stills...
(as done on http://www.vcdimager.org/stillencode/)
you'll find them in the usual .testing dir...
here some example run for creating a single SVCD PAL still.jpeg picture:
1) convert to YUV4MPEG2 format
(you can also use the ppmtoy4m-tool if you have a ppm format image)
make sure you have the right resolution (see the table at the bottom
web-encoder page...)
btw, those yuv files can get quite big... especially when trying to
create sequences...
$ ./jpeg2yuv-20010113.exe -n 1 -f 25 -I p -j still.jpeg > still.yuv
2) encode elementary video stream
("-T 160" tells mpeg2enc how much space (i.e. quality) to use for the
still picture...)
$ ./mpeg2enc-pth-20010113.exe -T 160 -f 7 -o still.m2v ./still.yuv
3) finally multiplex the stuff...
$ ./mplex-20010113.exe -f 7 -o still.m2p ./still.m2v
regards,
