Thx for the idea.
I downloaded it and tried it like this:
# perl -IVideo record-v4l2.pl --debug --no-record -d /dev/video0 -i 0 -s PAL -f
pal-europe -c 28 -W 384 -H 288
The output:
Debug = '1'
FrequencyTable = 'pal-europe'
VideoHeight = '288'
VideoDevice = '/dev/video0'
InputNum = '0'
VideoStandard = 'PAL'
TunerNum = '0'
VideoWidth = '384'
Warning: V4l2 driver = 'saa7134' does not support the ivtv "enhancements"!
All codec related options will be ignored.
Standard: 0x000000ff
Input: 0x00000000
0 0x000000ff PAL 1/25 625
1 0x00003000 NTSC 1001/30000 525
2 0x007f0000 SECAM 1/25 625
3 0x00000100 PAL-M 1001/30000 525
4 0x00000400 PAL-Nc 1/25 625
oldWidth = '-1', oldHeight = '-1'
Error in setResolution ioctl call!
I get a full grean picture already though :))
