680b3cee1f avcodec/h265_metadata: Add options to set width/height after crop
It's a common usecase to request a video size after crop. Before
this patch, user must know the video size before crop, then set
crop_right/crop_bottom accordingly. Since HEVC can have different
CTU size, it's not easy to get/deduce the video size before crop.
With the new width/height options, there is no such requirement.

47ba87551c checkasm/sw_rgb: test rgb24/bgr24 to yuv
The line width 8 is supposed to test corner case, while the
performance doesn't matter. Width 1080 is also a case of
unaligned to 16.

Width 1920 meant for benchmark (together with --runs options).

121fb846b9 lavc/vp7dsp: add R-V V vp7_idct_dc_add4uv
This is almost the same story as vp7_idct_add4y. We just have to use
strided loads of 2 64-bit elements to account for the different data
layout in memory.

T-Head C908:
vp7_idct_dc_add4uv_c:       7.5
vp7_idct_dc_add4uv_rvv_i64: 2.0
vp8_idct_dc_add4uv_c:       6.2
vp8_idct_dc_add4uv_rvv_i32: 2.2 (before)
vp8_idct_dc_add4uv_rvv_i64: 2.0

SpacemiT X60:
vp7_idct_dc_add4uv_c:       6.7
vp7_idct_dc_add4uv_rvv_i64: 2.2

225de53c9d lavc/vp8dsp: rework R-V V idct_dc_add4y
DCT-related FFmpeg functions often add an unsigned 8-bit sample to a
signed 16-bit coefficient, then clip the result back to an unsigned
8-bit value. RISC-V has no signed 16-bit to unsigned 8-bit clip, so
instead our most common sequence is:
    VWADDU.WV
    set SEW to 16 bits
    VMAX.VV zero     # clip negative values to 0
    set SEW to 8 bits
    VNCLIPU.WI       # clip values over 255 to 255 and narrow

Here we use a different sequence which does not require toggling the
vector type. This assumes that the wide addend vector is biased by
-128:
    VWADDU.WV
    VNCLIP.WI    # clip values to signed 8-bit and narrow
    VXOR.VX 0x80 # flip sign bit (convert signed to unsigned)

Also the VMAX is effectively replaced by a VXOR of half-width. In this
function, this comes for free as we anyway add a constant to the wide
vector in the prologue.

On C908, this has no observable effects. On X60, this improves
microbenchmarks by about 20%.

4e120fbbbd lavc/vp8dsp: add R-V V vp7_idct_dc_add4y
As with idct_dc_add, most of the code is shared with, and replaces, the
previous VP8 function. To improve performance, we break down the 16x4
matrix into 4 rows, rather than 4 squares. Thus strided loads and
stores are avoided, and the 4 DC calculations are vectored.
Unfortunately this requires a vector gather to splat the DC values, but
overall this is still a win for performance:

T-Head C908:
vp7_idct_dc_add4y_c:       7.2
vp7_idct_dc_add4y_rvv_i32: 2.2
vp8_idct_dc_add4y_c:       6.2
vp8_idct_dc_add4y_rvv_i32: 2.2 (before)
vp8_idct_dc_add4y_rvv_i32: 1.7

SpacemiT X60:
vp7_idct_dc_add4y_c:       6.2
vp7_idct_dc_add4y_rvv_i32: 2.0
vp8_idct_dc_add4y_c:       5.5
vp8_idct_dc_add4y_rvv_i32: 2.5 (before)
vp8_idct_dc_add4y_rvv_i32: 1.7

I also tried to provision the DC values using indexed loads. It ends up
slower overall, especially for VP7, as we then have to compute 16 DC's
instead of just 4.

30797e4ff6 lavc/vp8dsp: add R-V V vp7_idct_dc_add
This just computes the direct coefficient and hands over to code shared
with VP8. Accordingly the bulk of changes are just rewriting the VP8
code to share.

Nothing to write home about:
vp7_idct_dc_add_c:       1.7
vp7_idct_dc_add_rvv_i32: 1.2

67ca18dd56 lavc/hevcdec: drop HEVCLocalContext.gb
In all HEVCLocalContext instances except the first one, the bitreader is
never used for actually reading bits, but merely for passing the buffer
to ff_init_cabac_decoder(), which is better done directly.

The instance that actually is used for bitreading gets moved to stack in
decode_nal_unit(), which makes its lifetime clearer.

74159cbfc3 lavc/hevcdec: move handling of byte alignment at the end of slice header
Do it in hls_slice_header() rather than cabac_init_decoder() - the
former is a more logical place as according the spec the byte alignment
is a part of the slice header, not slice data. Avoids a second instance
of alignment handling in vaapi_hevc.

Also, check that alignment_bit_equal_to_one is, in fact, equal to one.

aacdec_usac: error out on too many elements
USAC supports up to 64 audio channels, but puts no limit on the total
number of extensions that may be present. Which may mean that there's
a single audio channel, with 65 thousand extension elements.

We assume that 64 elements is the maximum for now. So check the value.
