Dear PerlMonks, I am in need of capturing/grabbing frames via the aforementioned module. Unfortunately by running the following code:
#!/usr/bin/perl use strict; use Video::Capture::V4l; my $grab = new Video::Capture::V4l("/dev/video0") or die "Unable to op +en Video device: $!"; print "silent error:$!\n"; $grab->sync(0) or die "unable to sync: $!\n"; #
I obtain:
silent error: Illegal seek unable to sync: Invalid argument
That suggests v4l cannot lock and sync the frame 0. I have tested, successfully, my video input via mplayer through the following command:
mplayer -tv device=/dev/video0:input=2:driver=v4l2:width=320:height=24 +0:norm=ntsc:adevice=/dev/dsp tv://1 -zoom -aspect 4:3
This suggests I have to find a way to pass the -tv and the tv://1 options through Video::Capture::V4l. Do you happen to know how to do this? Thank you again in advance, CptSkripto
