v10 Update:
- FEATURE-COMPLETE!
No more features or filters will be added to this
patchset
- Added subscale filter
Provides high-quality scaling and rearranging
functionality for graphical subtitles.
This has been the last missing bit for making this
a useful and versatile toolset

These three are closely related and can't be separated easily:
In get_tag, the code was adding 22 bytes (in order to allow
it to hold 64bit numbers as string) to the value len for creating
creating a buffer. This was unnecessarily imposing a
size-constraint on the value_len parameter.
The code
The value_len is an uint32 not an int32 per spec. That
value must not be truncated, neither by casting to int, nor by any
conditional checks, because at the end of get_tag, this value is
needed to move forward in parsing. When the len value gets
modified, the parsing may break.
Signed-off-by:
get_value had a return type of int, which means that reading
QWORDS (case 4) was broken due to truncation of the result from
avio_rl64().

The spec allows attachment sizes of up to UINT32_MAX while
we can handle only sizes up to INT32_MAX (in downstream
code).
The debug.assert in get_tag didn't really address this,
and truncating the value_len in calling methods cannot
be used because the length value is required in order to

Fix 1: Commit c8140fe7324f264faacf7395b27e12531d1f13f7 had
introduced a check for value_len > UINT16_MAX.
As a consequence, attached images of sizes larger than
UINT16_MAX could no longer be read.
Fix 2: The value_len is an uint32 not an int32 per spec. That
value must not be truncated, neither

With the introduction of subtitle filtering, subsequent video frames
which are sharing the same data won't be as rare as this happened
to occur yet.
Ensuring per-frame uniqueness when data is modified is not only important
to avoid issues in the future, but a common API requirement anyway.

Hi,
for a new filter, I want to rescale PAL8 subtitle bitmaps where the palette
includes
colors with alpha.
From what I’ve seen, swscale doesn’t support PAL8-to-PAL8, only PAL8-to-BGR8
which doesn’t support alpha and the palette is fixed with 256 entries defined by
convention, while I would
