ok, i need more information:
1. try 'insmod ./sigma-test.ko' and post outout of dmesg
2. lspci -vv
3. kernel version and may be some other distribution details
4. if there is dmesg messages like 'kernel oops' during playing video, Post its here.
5. Try another m2v file (mpeg2 video stream file) instead of used before
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
i test a em8400 card
when i send m2v file to /dev/sigma/video
show picture serveral seconds then froze
system message is
SIGMA video 0: component output not supported by EM8400
what's the meaning
em84xx can't use this driver??
how to support component output
oh
i know em8400 not support component output
i use the svideo output, why the picture froze
What hardware do you use?
