Apparently, the alignment values are informative, rather than mandatory,
but the spec's wording makes it sound as if they're mandatory.
Previously floats where scaled up to 32bit int, but floats do not
have 32bits in their mantisse so a quarter of the bits where nonsense.
It seems no fate test is affected by this change, which is interresting

When seeking through MBAFF-coded H264, this can happen. Decoding calls end_frame
without calling start_frame. We are unable to decode this, as no frame
state has been set.
Happens for both VAAPI and Vulkan. Could be an issue elsewhere, hence
the individual commit.
There are circumstances where the flag isn't set but the skip mode
frames are. So don't use the inferred bit which has other inputs
when deciding to pass the skip mode frames to the device.
This fixes some decoding bugs on intel av1
Vulkan requires it.
It technically also requires use_default_scaling_matrix_mask,
but we can just be explicit and give it the matrix we fill in as-non
default.
The only thing besides the hwaccel that this function uses from
AVCodecHWConfigInternal is the pixel format, which should always match
the hwaccel one.
Will be useful in following commits.
