e29a99a975 fftools/ffmpeg_enc: don't ignore user selected chroma location 
This code always ignored the user-provided enc_ctx->chroma_sample_location
in favor of the location tagged on the frame. This leads to a very (IMHO)
unexpected outcome where -chroma_sample_location works differently from the
related options like -colorspace and -color_range, the latter of which
override the frame properties as a consequence of being configured on the
filter graph output.

The discrepancy comes from the fact that the chroma sample location does not
itself participate in filter graph negotiation.

Solve the situation by only overriding the enc_ctx option if it was left
unspecified by the user, and otherwise printing a warning if the requested
parameter does not match the frame parameter.

cd83161ff6 avcodec/vp9: fix leaked cbs fragment AVBufferRef 
When this function returns, the fragment is never reset, so
current_frag->data_ref is never unref-ed, which ends up leaking it.
We call ff_cbs_fragment_reset to release the reference on its buffer.

8e4c904c8e checkasm: ac3dsp: Increase the float tolerance for sum_square_butterfly_float 
Accept up to 13 ULP difference.

This fixes running "checkasm --test=ac3dsp 3044836819" on ARM.

Depending on how the SIMD implementations aggregate numbers,
larger/smaller values might not end up accumulated in exactly
the same way; the current NEON implementation for ARM aggregates
into vectors of 2 elements. If it would aggregate into vectors
of 4 elements instead, like the AArch64 version does, this particular
case would end up with a smaller difference.

26a2a76346 cbs_vp9: Fix VP9 passthrough 
Don't overwrite the bitstream values when updating the top-level loop
filter and segmentation state, instead do the update separately at the
end of the frame parsing.

This also reverts the change to the passthrough tests which made them
have output not matching the input.
