The calculation of width/height should round up, not round down to
prevent setting width or height to 0.
Also image->comps[compno].w is unsigned (at least in openjpeg2), so the
calculation could silently wrap around without the explicit cast to int.

This is a similar filter to f_metadata, only it works on side data. Since
adding side data from a user provided arbitrary binary string is unsafe,
because current code assumes that a side data of a certain kind has the proper
size, this filter only implements selection and deletion. Also, no value
matching support is implemented yet, because there is no uniform way to specify
a side data textually.

Use check_lib2 to test the header together with the function. This is
necessary, because '-DOPJ_STATIC' changes what the included header does.
Also add '-DOPJ_STATIC' to CPPFLAGS, so that it isn't necessary to
hardcode this in libavcodec/libopenjpeg{dec,enc}.c.
Finally, check for non-static openjpeg 2.1, too.

This fixes a build problem for MIPS architecture that looks like this:
libavcodec/mips/h264dsp_msa.c:2498:6: error: conflicting types for
‘ff_weight_h264_pixels16_8_msa’
void ff_weight_h264_pixels16_8_msa(uint8_t *src, int stride,
This bug was introduced by commit bc26fe8927:
avcodec/h264: Use ptrdiff_t for (bi)weight functions
That commit changed the data type of some function parameters in some
function definitions. However, the implementation of those functions in
libavcodec/mips/h264dsp_msa.c wasn't changed accordingly.

The hardware handling of packed bframes was always questionable but
it used to ok with my workaround. Today, not so much. But today we
have a bsf to unpack the bframes, so let's just use that and be
done with it.
With all the various refactorings that have happened over the years,
the current pts logic is very broken for non-trivial cases (ie: ones
where not every frame/field has a meaningful pts assocated with it).
Generally, we do not want to write AV_NOPTS_VALUE as the output
timestamp, regardless of anything else. It's better to pass zero
if there's no other information.
Additionally, interlaced content where the decoder returns each field
separately can result in the first field carrying the timestamp and
the second having AV_NOPTS_VALUE. It's clearly wrong to overwrite
the valid timestamp.
So, let's just never write AV_NOPTS_VALUE into an output frame.
Empirically, this fixed playback of interlaced mpeg2 and h.264 and
mpeg4-asp with packed b-frames in an avi container.
Using lfg was an overkill in this case where the random numbers
were only used for encoder descisions. Should increase result
uniformity between different FPUs and gives a slight speedup.

The parser for the outdef will accept a negative value for the first
named channel's gain. As negative values effectively only invert the
phase of the signal, and not negate the level, the gains' absolute
values must be used to correctly accumulate the levels.

The slice index expected by D3D11VA is the one from the texture not from the
array or texture/slices.
In VLC the slices we provide the decoder don't start from 0 and thus pictures
