Hi
I am using the Kfir1 driver on 2.4.18-3 kernel. We have added an ioctl command
which my application wants to check if the Video Source is active(present) or not.
Here is the code segment for it.
u32 *val = arg;
decoder_command(kfircurr, DECODER_GET_STATUS, val)
The value of the val is '1' from Composite Input, if the Composite
video input is connected from the DVD player and the player is
ON(i.e. source is active) and '0' if the source is not connected.
But, when I disconnect the Composite and connect the S-Video
cable of the DVD player and do this check, I do not get
value as 1. Basically, it does seem to detect for S-Video.
We have changed saa7113.c for DECODER_GET_STATUS switch
case to comment the following code to make it work properly
for Composite input.
/* switch (decoder->norm) {
case VIDEO_MODE_NTSC:
res |= DECODER_STATUS_NTSC;
break;
case VIDEO_MODE_PAL:
res |= DECODER_STATUS_PAL;
break;
default:
case VIDEO_MODE_AUTO:
if ((status & (1 << 5)) != 0) {
res |= DECODER_STATUS_NTSC;
} else {
res |= DECODER_STATUS_PAL;
}
break;
}
if ((status & (1 << 0)) != 0) {
res |= DECODER_STATUS_COLOR;
}
*/
But, if I do not do this 2 lines active Video check and
start the encoder with S-Video, it is OK and encodes properly
with S-Video.
This check is creating a problem only on S-Video and Composite is OK.
I need to do this check in my application.
Any suggestions on the Active Video check for S-Video.

Deepak
