Hello
I try to make VCD/SVCD from photos and camera's movies, but when it
comes to mpeg2enc it always fails with something like "memory protect
error". Why? Is my CPU to slow? Do I need special flags to every
concrete situation? Or maybe mpeg2enc is broken?
My stuff:
- Celeron 600; 128 MB RAM; HDD: 40GB,7200rpm,w/2048KiB Cache,UDMA(66)
- Linux 2.4.20/Debian 3.0 Woody
- mjpegtoos 1.6.1 (without jpeg-mmx, libmovtar and quictime4linux)
Simple example I tried:
jpeg --> SVCD

Last thing means in english something like "memory protect error".
And it always fails in the same point for every yuv-->mpg conversion
with mpeg2enc.
And another little problem... building jpeg-mmx fails with:
-----------------------------------------
[EMAIL PROTECTED] jpeg-mmx-0.1.4]$ make
nasm -f elf -o fdct_mmx.o fdct_mmx.s
fdct_mmx.s:394: error: operation size not specified
make: *** [fdct_mmx.o] Error 1
----------------------------------------
???
I will be very grateful for any help.
ps. I do not subscribe mjpeg-users mailing list... should I subscribe to
get an answer? How to subscribe?
