Export the poster_time_location if available. The poster_time_location is
calculated using the poster_time / time_scale = X seconds. The value of
poster_time_location indicates where in the video the poster frame is.

Hello,
This should address the issues found in the previous version, and vectors
loading the unfiltered data.

On most cases, the vector type (VTYPE) for the RISC-V Vector extension
is supplied as an immediate value, with either of the VSETVLI or
VSETIVLI instructions. There is however a third instruction VSETVL
which takes the vector type from a general purpose register. That is so
the type can be selected
This is implemented for a vector size of 128-bit. Since the scalar
product in the inner loop covers 5 samples or 160 bits, we need a group
multipler of 2.
To avoid reconfiguring the vector type, the outer loop, which loads
multiple input samples sticks to the same multipler. Consequently, the

This adds a variant of the postfilter for use with 256-bit vectors.
As a single vector is then large enough to perform the scalar product,
the group multipler is reduced to just one at run-time.
The different vector type is passed via register. Unfortunately,
there is no VSETIVL instruction, so th
This adds a variant of the postfilter for use with 512-bit vectors.
Half a vector is enough to perform the scalar product. Normally a whole
vector would be used anyhow. Indeed fractional multiplers are no faster
than the unit multipler.
But in this particular function, a full vector makes up 16 sa

This codec uses BswapDSP, BlockDSP and IDCTDSP.
The former never used MMX, the latter does not use it

ff_square_tab is always used with an offset; if this table
is marked as hidden, the compiler can infer that it and
therefore also ff_square_tab + 256 have a fixed offset
from the code. This allows to avoid performing "+ 256"
at runtime by baking it into the offset from the code to

(There is a small issue that is now being treated differently:
The earlier code would record a position in a buffer that
is being written to via put_bits(), then write data,
then overwrite the byte at the position recorded earlier

Any chance of someone finding the time to have a look at this?
