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 :)) -- Robert L. RAKSI -- The Microsoft of Borg: Patches Are Futile! --
