bttv errors in system log

[philipt]

Hi, has anyone seen these errors before in the system log? It's ZM 1.27 on CentOS 7 and an BT878 video capture card on /dev/video0.

'kernel: bttv: 0: timeout: drop=31600 irq=138887/138888, risc=c8acb01c, bits: HSYNC OFLOW'

About once a second. I've set fps=3 secs and 320x240, 8 bit grey scale.

Thanks! Philip.

Yeah I have them... there is a module parameter to turn them down..... google v4l bttv parameters for details.

modern v4l development is unfortunately less than optimally documented.
