[MPlayer-dev-eng] [patch] division by zero in stream/tvi_v4l2.c when norm not set

[Jarek Czekalski]

I capture from usb camera with mencoder and v4l2. There's a problem in setting
a norm form v4l2 with this hardware. Then "Floating point exception is
reported". Division by zero in stream/tvi_v4l2.c. The calculation performed
there is only to report a warning message.

I patched code just checking if the divider is
zero and then omit the test. Attached diff. After applying the diff recording
seems to go well.

Regards
Jarek
