Ah indeed, sorry. Patch with trivial fix will follow.
But besides that, I came across another thing I do not completely
understand: Does bgr0 mean that the last byte is guaranteed to be zero, or
that it is simply not taken into account by the encoder/decoder?
I ask because I'm not able to get equal framemd5 when comparing with bgr0.
But it does work with bgr24.

I have not measured, but it will be slower because of the
Micheal, do you think it's worth doing measurements, or shall I just
duplicate the function to avoid the if(), and thus any possible speed loss?
