possible fix (is 0 a valid value?)

Program received signal SIGFPE, Arithmetic exception.
0x00007fffe5c86f07 in handleVAEncSequenceParameterBufferType (drv=0x5555557ec2b0, context=0x555555a42c70, buf=0x555555819000)
    at /var/tmp/paludis/media-libs-mesa-9999/work/mesa-9999/src/gallium/state_trackers/va/picture.c:374
374     in /var/tmp/paludis/media-libs-mesa-9999/work/mesa-9999/src/gallium/state_trackers/va/picture.c

What happens is that h264->intra_idr_period is 0, which with current parenthesizing results in a division by 0.

Command used :
