where does 20480/0 turn into 20480/1 ? or did i misunderstand this?
It seems that denominator 0 is replaced with 1
The specification says that if either the numerator or the
denominator is zero then the SAR is to be intended unspecified.
Internally ffmpeg represents an unspecified SAR as 0/1, while
fractions with a zero denominator are not handled properly;
so we bridge the gap by replacing x/0 with 0/1.
Signe
I'm a bit confused because the calculation here goes up to 32 bits and then
returns to 8 bits. It seems that the vmax and vnclipu instructions can't be
removed by using round-related instructions？

This puts lavu frame buffer allocator helpers in sync with lavc's decoder frame
buffer allocator's STRIDE_ALIGN define.
Remove the comment about av_cpu_max_align() while at it as using it is not
ideal when CPU flags can be changed mid process.
Should fix ticket #6.

Thank you for the detailed explanation. One more question: I understand
that assembly code needs to be further broken down, but what's the issue
with adding this code to the init section of the C code here? I think this
C code is just mimicking the init section of the C code in x86.

This is really just a wrapper for idct4_add16intra, which is in turm mostly
a wrapper for idct4_add and idct4_dc_add.
For benchmarks refer to the later two.

The snow encoder uses block based motion estimation which can read out of array
if
insufficient alignment is used
It may be better to only apply this for the encoder, as it would safe a few
bytes of memory
for the decoder. Until then, this fixes the issue in a simple way.

Hi, good day,
I think something is wrong with this v2 patch, it is showing as corrupt in
the patchwork system.
See here:
https://patchwork.ffmpeg.org/project/ffmpeg/patch/69b8a7a5-3826-4aef-88e1-2984d61a5...@skybound.link/
By chance did you modify the .patch file directly?
