Ok, i cracked it. This is what works.
/usr/bin/ivtvctl -d /dev/video0 -u 0x3000
/usr/bin/ivtvctl -d /dev/video0 -u 0xff
/usr/bin/ivtvctl -p 0
/usr/bin/ivtvctl -f width=720,height=576
/bin/sleep 2s
I noticed something fun. If i "just" did the -u 0xff as the first command.
It does not print anything to my syslog. But, if i use 0x3000 as the first
command, it DOES write
Nov 29 20:55:40 mythbox kernel: saa7115: decoder set norm NTSC
Nov 29 20:55:40 mythbox kernel: saa7115: set audio: 0x01
Nov 29 20:55:40 mythbox kernel: saa7127: Setting Encoder Video Standard
Nov 29 20:55:40 mythbox kernel: saa7127: Set NTSC Video Mode
Nov 29 20:55:40 mythbox kernel: saa7127: Selecting NTSC video Standard
And then the 0xff shows
Nov 29 20:55:42 mythbox kernel: ivtv: Switching standard to PAL.
Nov 29 20:55:42 mythbox kernel: saa7115: decoder set norm PAL
Nov 29 20:55:42 mythbox kernel: saa7115: set audio: 0x01
Nov 29 20:55:42 mythbox kernel: saa7127: Setting Encoder Video Standard
Nov 29 20:55:42 mythbox kernel: saa7127: Set PAL Video Mode
Nov 29 20:55:42 mythbox kernel: saa7127: Selecting PAL video Standard
Funny phenomenon?
