The input file is MPEG range, so we should also encode to MPEG range
before comparing against it. This bug was avoided in the past because
YUVJ inputs were automatically converted back to limited range when converting
to a different pixfmt (in the absence of tagging). However, with proper YUV
negotiation in place, the default behavior is to preserve the YUV range
wherever possible. Since `rawvideo` does not signal or care about the YUV
range, we need to explicitly request the desired output range to force a
conversion.
Affects all rawvideo tests, in particular vsynth and owdenoise.
The test constructs 66 sine waves of different frequencies and joins
them into a 7th order ambisonic layout with extra non-diegetic
stereo. The channels are then shifted circularly with channelmap and
separated into individual streams for muxing with channelsplit.
Note that the last step is necessary because swr is not capable of
interleaving planar to packed for more than 64 channels, which would be
necessary to mux such a stream as PCM.
This reverts commit 110d8549d5.
I have been working through fixing bugs, particularly crashes I've
found using a fuzzer, in the VVC decoder for the past few months.
While I won't claim it is now bug-free, it is considerably more
resilient than it was and I think in a position to have the
experimental flag removed for release 7.1.
Additionally, most of the Main 10 features of VVC which were missing
version of the decoder released in 7.0 have now been implemented.
This includes the most major missing features: IBC, subpictures and RPR.

Fix "ost->st->avg_frame_rate = ost->frame_rate" in streamcopy_init()
being reset to input's frame rate a few lines below.
Note that in current code, there are some discrepancies amongst the
muxers. For example, avienc relies on time_base, so it is not affected
by this patch, whereas mxfenc and matroskaenc do use avg_frame_rate,
so this patch fixes -r being honored.
In the updated fate test, the input is (wrongly) probed as 50fps. With
this patch, the correct value (25fps) is successfully forced with -r.

The time_base was a bad guess.
Currently, fate-time_base test data assumed that overriding the input
time_base would affect the frame_rate, but this behaviour is not
documented, so just fix the fate data now that this is fixed.
Fix regression since 10185e2d4c1e9839bc58a1d6a63c861677b13fd0:
previously, when streamcopying, the time_base was guessed from the
frame_rate considering it is often constant, so guessing the frame_rate
back from the time_base was often not a problem.

Replace the manually specified chroma location by one using standard
notation, arbitrarily "bottomleft" as it is a less common path.
Required if we want to phase out the use of manual chroma locations.
Encoders may emit a buffering period SEI without a corresponding
SPS/PPS if the SPS/PPS is carried out-of-band, eg with avcc.
During Annex B conversion, this may result in the SPS/PPS being
inserted *after* the buffering period SEI but before the IDR NAL.
Since the buffering period SEI references the SPS, the SPS/PPS
needs to come first.

F and D extensions are included in all RISC-V application profiles ever
made (so starting from RV64GC a.k.a. RVA20). Realistically they need to be
selected at compilation time.
Currently, there are no consumers for these two flags. If there is ever a
need to reintroduce F- or D-specific optimisations, we can always use
__riscv_f or __riscv_d compiler predefined macros respectively.
This preserves T1 whilst calling the instrumented function. In a Sci-Fi
setting where type-based Control Flow Integrity (CFI) is supported, the
calling code (i.e., the `checkasm` test case) will set T1 to the expected
value of the landing pad label (LPL) of the instrumented function.
The call wrapper will always use LPL zero which is a wild card. We should
preserve the value of T1 at least until the indirect call to the
instrumented function. Of course this is Sci-Fi, because:
1) there is no hardware (or even QEMU) support yet,
2) all our assembler functions currently use LPL zero anyway.
This uses T3 rather than T2 because indirect branches with T2 is reserved
for notionally direct calls made with an indirect call instruction (e.g.
due to GOT indirection), and are exempted from forward-edge CFI checks.
The B extension was finally ratified in May 2024, encompassing:
- Zba (addresses),
- Zbb (basics) and
- Zbs (single bits).
It does not include Zbc (base-2 polynomials).
Increase the tolerance from 10 ulp to 11 ulp. This fixes occasional
errors for some inputs; the errors could be reproduced on
aarch64/neon builds, with "checkasm --test=ac3dsp 3446175925".

This test confirms that we can write mDCv and cLLi chunks and read them
back via the png decoder. It uses an HEVC conformance sample with this
metadata as the base source for the side data in the frames.
