a00072a9d5 libswscale: force a minimum size of the slide for bayer sources 
Bayer sources are read in groups of 2 lines (e.g. for a
BGGR flavor, the first row contains only B and G samples,
while the second row contains only G and R samples). They
need to be read as a whole.

ddf3bedfb8 lavc/videotoolbox: do not pass AVCodecContext to decoder output callback 
The opaque parameter for the callback is set in videotoolbox_start(),
called when the hwaccel is initialized. When frame threading is used,
avctx will be the context corresponding to the frame thread currently
doing the decoding. Using this same codec context in all subsequent
invocations of the decoder callback (even those triggered by a different
frame thread) is unsafe, and broken after
cc867f2c09, since each frame thread now
cleans up its hwaccel state after decoding each frame.

Fix this by passing hwaccel_priv_data as the opaque parameter, which
exists in a single instance forwarded between all frame threads.

The only other use of AVCodecContext in the decoder output callback is
as a logging context. For this purpose, store a logging context in
hwaccel_priv_data.

57e15b2e07 avformat/cafenc: derive Opus frame size from the relevant stream parameters 
Use the stream duration as last resort, as an off-by-one result of the
"st->duration / (caf->packets - 1)" calculation can break playback on some
devices.
Also, don't write the sample_rate value propagated by encoders like libopus.
The sample rate of the audio fed to it is irrelevant after being encoded.

Fixes ticket #9930.

c1b8ffbed8 avcodec/arm/sbcenc: avoid callee preserved vfp registers 
When compiling FFmpeg with GCC-9, some very random segfaults were
observed in code which had previously called down into the SBC encoder
NEON assembly routines. This was caused by these functions clobbering
some of the vfp callee saved registers (d8 - d15 aka q4 - q7). GCC was
using these registers to save local variables, but after these
functions returned, they would contain garbage.

Fix by reallocating the registers in the two affected functions in
the following way:
 ff_sbc_analyze_4_neon: q2-q5 => q8-q11, then q1-q4 => q8-q11
 ff_sbc_analyze_8_neon: q2-q9 => q8-q15

The reason for using these replacements is to keep closely related
sets of registers consecutively numbered which hopefully makes the
code more easy to follow. Since this commit only reallocates
registers, it should have no performance impact.

068faf4f74 avfilter/vf_scale: overwrite the width and height expressions with the original values 
Instead of the potentially adjusted ones. Otherwise, if config_props() is
called again and if using force_original_aspect_ratio, the already adjusted
values could be altered again.

Example command line
scale=size=1920x1000:force_original_aspect_ratio=decrease:force_divisible_by=2

user value 1920x1000 -> 1920x798 on init_dict() -> 1918x798 on frame
change when eval_mode == EVAL_MODE_INIT, which after e645a1ddb9 could be at the
very first frame.

This state is not refcounted, so make sure it always has a well-defined

this commit also solves that issue in a more general way.
