This made the output non binary reproducible across different versions of
zlib.

The demuxer's 'missing_streams' private option is used to communicate
information from the demuxer to avformat_find_stream_info(). However,
that is not only unnecessarily complicated, it also leaks internal
information to users, e.g. this option appears in the results of the
fate-flv-demux test.
Use a new field in FFFormatContext to communicate this information
instead.
This function would otherwise fail to build on the next major bump, as
inject_global_side_data is marked for removal.
It should also never be needed, as there is now a mechanism for
supplying global side data to decoders directly.
stddev and PSNR values change by the removal of format conversion and because
of the added sws_flags. Either or will have the same effect even on their own.

This change will save approximately 531 MB for an 8K clip when processed with 16 threads.
The calculation is as follows:
7680 * 4320 * sizeof(int) * 2 * 2 * 16 / (4 * 4).
The deblock boundary strength stage utilizes ~5% of CPU resources for 8K clips.
It's worth considering it as a standalone stage. This stage has been relocated
to follow the parser process, allowing us to reuse CUs and TUs before releasing them.
This function is only used for filtering and generic compute.
The issue is that a view inherits the usage flags from the image
by default, and the spec says the view format must be compatible
with the usage. VkImageViewUsageCreateInfo allows us to filter out
the indeded uses of the imageview.
Pffff.
When using **integer** images inside shaders, it turns out
that conversion doesn't automatically happen, but we need to
explicitly use the imageviews to get the image exposed as
a suitable representation for the shader.
Finally enables bitexact image representations.
This format is useful for doing certain lossless transforms on images,
RCT in particular, which require you to escalate the size from 16 to
32 bits to avoid overflows.
APIchanges will be done alongside when comitting.
Broken after 7753a9d627. Apply only the
whitelist early, and the rest with a single call to av_opt_set_dict2()
with AV_OPT_SEARCH_CHILDREN, which should be equivalent to the original
behaviour.
