x264 is a free library for encoding H.264/AVC (aka MPEG-4 Part 10)
video streams.
Encoder features
* CAVLC/CABAC
* Multi-references
* Intra: all modes (4x4 and 16x16 with all predictions)
* Inter P: all partitions (from 16x16 down to 4x4)
* Inter B: partitions from 16x16 down to 8x8 (including SKIP/DIRECT)
* Ratecontrol: constant quantizer, constant bitrate, or multipass ABR
* Scene cut detection
===> The following configuration options are available for libx264-0.165.3223_1:
ASM=on: Use optimized assembly code
LTO=on: Use Link-Time Optimization
OPTIMIZED_CFLAGS=on: Use extra compiler optimizations
===> Use 'make config' to modify these settings
multimedia/*x264: Update to 0.165.3223 and transfer maintainership
* Switch to GStreamer's meson branch as it simplifies builds and is
faster
* Transfer maintainership to multimedia
* Remove DEBUG, GPAC, OPENCL and PGO options
By switching to Meson we can utilize the framework for debug builds
GPAC is broken upstream
OPENCL (lookahead) has very little advantage now that core count for
CPUs are much higher than a decade ago and with x264's limited
parallelization. It's also much simplier than x264's other code paths.
PGO pulls in GCC with no to little benefit
* Add LTO and OPTIMIZED_CFLAGS options
Available only on aarch64 and amd64, enabled by default

multimedia/libx264: add -znotext to LDFLAGS on i386, for lld
Example error:
/usr/bin/ld: error: can't create dynamic relocation R_386_PC32 against
symbol: gettimeofday in readonly segment; recompile object files
with -fPIC
This port links some non-PIC code, which fails with lld as it defaults
to disallowing relocations against read-only segments. For i386 we can
just add -znotext unconditionally: for GNU BFD ld it just affirms BFD's
existing default.

Remove "-march=i686 -mfpmath=sse -msse" and "-msse2" on later versions

relies on CPUID but may pessimize compiler (around 2.3 % on Skylake).

Our stdint.h is a symlink to sys/stdint.h so we need to teach x264 the
header guard of the sys/stdint.h file. Otherwise compiling software with the
x264.h header will generate a warning about the mismatch header guard.

multimedia/libx264: Fix PGO/GCC options
- Revert options helpers for PGO and GCC .. *shakes fist*. We end up
setting USE_GCC=yes yes otherwise, and that's not valid.
- libx264 and x264 share the same distfiles, use the same DIST_SUBDIR
multimedia/x264: General overhaul
- Split x264 into two ports: the CLI application (x264), and the library
(libx264). This will allow x264 to use lavf and friends from ffmpeg for
decoding and demuxing while preventing a circular dependency between the
two: x264 can depend on ffmpeg, but ffmpeg will depend on libx264 rather
than x264.
- Add the LAVF option to the CLI port, making the dependency on ffmpeg
optional.
- Update to 0.142.2455.
- Amend fixes to local patches so that they can apply to the new upstream
files.
- Provide the git revision and other version information to the build
environment, allowing the CLI binary to display this information (like the
Windows builds).
- Remove unsupported build options (X11_OUTPUT).
- Ensure that the library and CLI ports each have the appropriate options.
- Add notes for future contributors who wish to update the ports.
- Bump PORTREVISION for all dependent ports.
