134233972e lavc/utvideoenc: Set bits_per_coded_sample for rgba. 
Allows to write correct value for biBitCount into BITMAPINFOHEADER.
Before, ff_put_bmp_header() always wrote "24" as biBitCount
for utvideo because bits_per_coded_sample was never set by the
encoder.

c1173437fc avcodec/ffv1enc: Fix storing RGB48 without explicitly set level 
the bps value is only stored with level >= 1, using rgb48 with level 0 requires the
user app to keep track of the bps by external means, which does not always happen
also we force level >= 1 for other 16bps formats, so this is consistent.

be885da342 vp9: change order of operations in adapt_prob(). 
This is intended to workaround bug "665 Integer Divide Instruction May
Cause Unpredictable Behavior" on some early AMD CPUs, which causes a
div-by-zero in this codepath, such as reported in Mozilla bug #1293996.

Note that this isn't guaranteed to fix the bug, since a compiler is free
to reorder instructions that don't depend on each other. However, it
appears to fix the bug in Firefox, and a similar patch was applied to
libvpx also (see Chrome bug #599899).
