[byavl]

Hi All

I got problems when try encode VHS to MPEG2.
Source file that I have is in MJPG.
I try many ways to encode, but either some SIGSEGV was happened...

And other scary message.

But I had detect option that is reason of my trobles.
It is option "v4mv".
In any option variants with v4mv unpredictable result is appearing.
For example with ":v4mv:psnr:" and sigsegv welcome.

I hope guys fixed it... :)

Thanks and best regards.
