Closes #9.

Bug report by Sam Panzer.

And other resolution dependent buffers checks.
Closes videolan/x264#10.

Fix crash of MSVC builds compiled with --system-libx264 and /MT (default) CRT.

Removes need for -Bsymbolic during linking.

Simplifies a lot of code and avoids having to export public asm functions.

Note that the force_align_arg_pointer function attribute is broken in clang
versions prior to 6.0.1 which may result in crashes, so make sure to either
use a newer clang version or a different compiler.

pkg-config doesn't like spaces in version string.

Some hardware decoders reject to decode streams with non-zero
constraint_set4_flag/constraint_set5_flag.

Result was never used in that case.

Bug report by Xuezhi Yan.

Bug report by Hongxu Chen.

It now includes pkg-config, so lavf can be detected.

Supported targets:
 - debian amd64
 - debian aarch64
 - windows 32 bit
 - windows 64 bit
 - macos 64bit

The tests are ran on all supported targets (via wine on windows).

The release jobs are only available on master/stable branches in
videolan/x264 repository, and must be ran manually when a developer
wishes to upload the artifacts.

This will break decoding with older versions of FFmpeg/Libav.

Warn when the following are used without the appropriate cpuflag:
 * YMM and ZMM registers
 * 'pextrw' with a memory operand
 * GPR instruction set extensions

Allows for marking symbols as having limited global scope, similar to
using 'hidden' symbol visibility on ELF.

Allows for automatic command line completion for both options and values.

Options such as --input-csp and --input-fmt will dynamically retrieve
supported values from libavformat when compiled with lavf support.

Execute 'source tools/bash-autocomplete.sh' in bash to enable.

Progressive High, Constrained High, and Progressive High 10.

Even in Main profile, constraint_set4_flag is now set to 1 if progressive,
and constraint_set5_flag is set to 1 if no B-slices are present.

Around a ~1% speedup to the overall encoding for --slow.

Luca Barbato authored 6 years ago and Anton Mitrofanov committed 6 years ago

No overall speedup, just tidier code.

Luca Barbato authored 6 years ago and Anton Mitrofanov committed 6 years ago

Seems to give about a 1-2% overall speedup on --slow.

Yet another use of xxpermdi, another 10% gain.

Luca Barbato authored 6 years ago and Anton Mitrofanov committed 6 years ago

About 20% faster.
