c28ed1d743 h264: move [uv]linesize to the per-slice context 
While it is a per-frame variable, it is only really used in the
low-level decoding code, so it is more efficient to store it in the
slice context.

a12d3188cb h264: use a smaller struct for the ref lists 
There is no need to store a whole H264Picture, with a full AVFrame
embedded in it. This should allow getting rid of the embedded AVFrame
later.

36d04801ba h264: move the scratch buffers into the per-slice context 
Also change the method for allocating them. Instead of two possible
alloc calls from different places, just ensure they are allocated at the
start of each slice. This should be simpler and less bug-prone than the
previous method.

30e6abd1a8 webp: ensure that each transform is only used once 
According to the WebP Lossless Bitstream Specification
"each transform is allowed to be used only once".

If a transform is more than once this can lead to memory
corruption.

7b05b5093e ac3dec_fixed: always use the USE_FIXED=1 variant of the AC3DecodeContext 
The AC3DecodeContext has a float (USE_FIXED=0) and an integer
(USE_FIXED=1) variant, both of which can be present in the same binary.
This is not only very confusing, but it also breaks horribly, when one
variant is used by code expecting the other.

This currently happens, because eac3dec.c is only compiled for the float
variant, but also used from ac3dec_fixed.c, which uses the integer
variant.

The result is memory corruption, leading to crashes.

So compile eac3dec.c once for each variant and adapt it, so that it
works with the integer variant.

A loss of precission and scaling bug has been fixed by the committer

This mainly consists of replacing all the pointer arithmatic 'addiu'
instructions with PTR_ADDIU which will handle the differences in pointer
sizes when compiled on 64 bit mips systems.

The header asmdefs.h contains the PTR_ macros which expend to the correct mips
instructions to manipulate registers containing pointers.

eae13eae9d configure, mips: remove MIPS32R2, merging it with MIPSFPU 
There are no independant uses of mips32r2 instructions except for the
FPU parts. Due to the heavy use of mips32r2 specifc fpu extensions, I
am guessing the original author intended MIPSFPU to imply MIPS32R2 anyway.

Since these fpu instructions are available on mips64 (non-r2), enable them
there as well.

Also remove the last occurence of HAVE_MIPS32R2 (which is coupled to
HAVE_MIPSFPU anyway).

mips32r2 is left in the list of options form compatability so that using
--disable-mips32r2 doesn't break anything.

87e85a133f aac: Relax reserved_bit validation 
Although the specification mandates this bit to zero, it may happen
that software tools incorrectly flip it to one, invalidating a possibly

Relax this restriction, by failing only when AV_EF_BITSTREAM is set.
This behaviour is similar to aac decoders in Firefox and Quicktime.

37ffe7f90a mips/aaccoder: use variables instead of using register names directly 
On mips64, the registers t[4-7] do not exist. Instead of using a lot of #ifdef
or defines to handle differing register names, use variables and let GCC
allocate the registers automatically (like in the other mips assembly files).

In get_band_cost_ESC_mips, t4 and t5 were renamed to t6 and t7 to avoid a
variable name conflict.

Normally the aic decoder finds the proper slice combination (multiple of

default values, which were actually swapped.
The number of slices is modified to account for such odd width cases.

6394acaf36 AAC: Fix M/S stereo encoding 
This patch fixes a pointer arithmetic bug in adjust_frame_information that resulted in heavily corrupted audio when using M/S encoding. Also, a backup copy of untransformed coefficients has to be kept around or attempts at re-processing the frame (which happens when hevavily overspending bits during transients) will result in re-encoding of the coefficients and subsequent corruption of the resulting stream.

A/B testing shows the bug as corrected, but still cannot prove that M/S coding is a win at least in numbers. Limited listening tests do show improvement on M/S encoded samples in lower bitrates, but they're hidden among the other artifacts that remain to be corrected in the encoder.

Some of the regressions flagged in the report do show poor stereo image (but not buggy), so M/S encoding is clearly not good enough yet to be defaulted to auto.

In numbers, Patched against Unpatched, stereo_mode auto:

84f4be424d avcodec/aacpsy: Fix AAC Psy PE reduction calculation when multiple iterations are required 
This is a small change, but it does have a big impact on bit allocation.

all the regressions marked in the report have no audible
difference (I didn't check them all though), but the improvements can
be heard.

This affects mostly high bit rates. It's related to issue #2686.

In the report, A is the patched version, B is unpatched, all
comparisons show deltas in the form (A-B), so a positive pSNR delta
means a better quality in the patched version, and negative a
regression. Regressions are only considered for pSNR deltas below
-1db, they're considered serious below -6db.

All measurements were done with tiny_psnr.

The summary of the report inline for quick reading:

Files: 58
Bitrates: 6
Tests: 347
Serious Regressions: 0 (0%)
Regressions: 10 (2%)
Improvements: 54 (15%)
Big improvements: 26 (7%)

50833c9f7b Fix buffer_size argument to init_put_bits() in multiple encoders. 
Several encoders were multiplying the buffer size by 8, in order to get
a bit size. However, the buffer_size argument is for the byte size of
the buffer. We had experienced crashes encoding prores (Anatoliy) at
size 4096x4096.

b9de1303a6 mips/acelp_filters: fix incorrect register constraint 
Change register constraint on the v variable from = to +. This was causing GCC
to think that the v variable was never read and therefore not initialize it.

This fixes about 20 fate failures on mips64el.

generally only called a few times at the streams start.

a83b6b077c vp9: assign PTS to visible instead of invisible frames 
All the webm/vp9 files I have seen so far can have packets that contain
1 invisible and 1 visible frame. The vp9 parser separates them. Since
the invisible frame is always (?) the first sub-packet, the new packet
is assigned the PTS of the original packet, while the packet containing
the visible frame has no PTS.

This patch essentially reassigns the PTS from the invisible to the
visible frame.

d20df2601f avcodec/nvenc: De-compensate aspect ratio compensation of DVD-like content. 
For reasons we are not privy to, nvidia decided that the nvenc encoder
should apply aspect ratio compensation to 'DVD like' content, assuming that
the content is not bt.601 compliant, but needs to be bt.601 compliant. In
this context, that means that they make the following, questionable,
assumptions:

1) If the input dimensions are 720x480 or 720x576, assume the content has
an active area of 704x480 or 704x576.

2) Assume that whatever the input sample aspect ratio is, it does not account
for the difference between 'physical' and 'active' dimensions.

From, these assumptions, they then conclude that they can 'help', by adjusting
the sample aspect ratio by a factor of 45/44. And indeed, if you wanted to
display only the 704 wide active area with the same aspect ratio as the full
720 wide image - this would be the correct adjustment factor, but what if you
don't? And more importantly, what if you're used to ffmpeg not making this kind
of adjustment at encode time - because none of the other encoders do this!

And, what if you had already accounted for bt.601 and your input had the
correct attributes? Well, it's going to apply the compensation anyway!
So, if you take some content, and feed it through nvenc repeatedly, it
will keep scaling the aspect ratio every time, stretching your video out
more and more and more.

So, clearly, regardless of whether you want to apply bt.601 aspect ratio
adjustments or not, this is not the way to do it. With any other ffmpeg
encoder, you would do it as part of defining your input paramters or
do the adjustment at playback time, and there's no reason by nvenc
should be any different.

This change adds some logic to undo the compensation that nvenc would
otherwise do.

nvidia engineers have told us that they will work to make this
compensation mechanism optional in a future release of the nvenc
SDK. At that point, we can adapt accordingly.
