I am trying to encode video from my Microdia webcam (usb 0c45:62c0), using the v4l2 driver. I can capture video just fine, but I keep getting a "Floating point exception" when I try to include audio (details below). Is this a known bug? -David The following successfully captures video (with no sound, obviously): mencoder -srate 48000 \ -fps 20000/1001 \ -ofps 20000/1001 \ -tv driver=v4l2:device=/dev/video0:outfmt=yuy2:input=0:noaudio \ tv:// -ovc lavc -o test.avi But this results in a SIGFPE: mencoder -srate 48000 \ -fps 20000/1001 \ -ofps 20000/1001 \ -tv driver=v4l2:device=/dev/video0:outfmt=yuy2:input=0:forceaudio:alsa:adevice=hw.0,0 \ tv:// -ovc lavc -oac lavc -o test.avi MEncoder dev-SVN-rUNKNOWN-4.1.2 (C) 2000-2006 MPlayer Team CPU: Intel(R) Core(TM)2 CPU T5200 @ 1.60GHz (Family: 6, Model: 15, Stepping: 6) CPUflags: Type: 6 MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1 Compiled with runtime CPU detection. success: format: 9 data: 0x0 - 0x0 TV file format detected.
