[mpeg2] Re: Trying to get Kfir board to run, read 0 byte data

["Niu Ding" <niuding@hotmail.com>]

Hi Torsten,

Thanks for your quick response. I did exactly the same as you:

for NTSC video source:
  insmod kfir.o vidinmode=1 vidoutmode=0 vidinput=0

For PAL source:
  insmod kfir.o vidinmode=0 vidoutmode=1 vidinput=0

But got 0 byte data. I wrote a simple C program, after open the video 
device, it stuck in read().

What kind of system are you using? I am using an Compag PC with AMD 800Mhz.

Thanks,

Niu Ding
