Mark,
The easiest solution is most probably to use OpenMP if you have a serial
program up and running. it consists "simply" of adding pragmas to the serial
code. Any compiler should be able to handle this today. This avoids going to
the basics like pthreads. It's a fast solution, but it's effic

computer. I am running SuSE Linux 10.1 (32 bit) on an Athlon 64 X2 3800+. I

Hi,
I have another capturing problem with very old VHS tapes. I am using a Canopus
ADVC-55 for capturing to PAL-DV. Even if my tapes are very old, I do not have
any problem with lost frames, drops outs etc. My problem seems to be a
synchronization issue of the individual scan lines. In some fra

I am interested in capturing my analog material to dv. On this list, the

Are there any other hard or software solutions for that purpose

Hallo,
I am using mjpegtools for a rather long time for the restoration of very old
VHS sources. But now I met a problem where I do not know how to proceed.
The material which I have (already in MJPEG format) comes from 45+ years old
8mm material. Most of it is bw but some takes are colored.
