Hi all,
My aim is to set up a real time video capture system via DM6446 board
(2.6.10_mvl402) in linux(Centos5 2.6.18-8.el5).
I use a CCD Color camera(PAL) via BNC connecter and a Color TFT LCD
Monitor(PAL).
I set the SW3-10 to on.
The problems came out when I encode and decode the demos:
root=/dev/hda1
[EMAIL PROTECTED]:/opt/dvevm#./loadmodules.sh
insmod:error inserting'cmemk.ko': -1File exists
insmod:error inserting'dsplinkk.ko':-1 File exists
[EMAIL PROTECTED]:/opt/dvevm#./encode -v test.mpeg4 -t 20
Encode demo started
Win:1, hfactor:0,vfactor:0

System halt.
