* commit 'a7c1689d':
  4xm: check that bits per sample is strictly positive
Merged-by: Michael Niedermayer <michaelni@gmx.at>

The check added in df33a58e does not work
at all, rather it broke the summing of bitrates completely.
The comparission was wrong way around.
This commit replaces it by a simpler and hopefully clearer check

of the codepath.

The added check is redundant.
It shows the error path more clearly though

An alternative to this would be to change the code to support any
stride.
The condition of differing strides should be rare.
If theres no speedloss supporting any stride would be better

The pixel format descriptors are set to more or less arbitrary
values as bayer formats do not fit in the descriptors structure.
These values are currently not used for bayer formats and thus
do not matter.
