From c67ba9f70c41e158a7b3d62f968fb45e095578f4 Mon Sep 17 00:00:00 2001 From: arch1t3cht Date: Fri, 13 Oct 2023 23:46:11 +0200 Subject: [PATCH] Update ffmpeg wrap to 6.0 following ffms2 updates Also bump libdav1d and turn the wrap patches into diffs. This requires bumping the minimum meson version to 0.63, but meson 1.0 is available pretty much everywhere now so this should be fine. --- meson.build | 2 +- subprojects/dav1d.wrap | 4 +- subprojects/ffmpeg.wrap | 4 +- subprojects/packagefiles/dav1d/0001.patch | 39 + .../packagefiles/dav1d/src/meson.build | 366 --- subprojects/packagefiles/ffmpeg/0001.patch | 100 + subprojects/packagefiles/ffmpeg/meson.build | 2750 ----------------- subprojects/packagefiles/ffms2/meson.build | 4 +- 8 files changed, 146 insertions(+), 3123 deletions(-) create mode 100644 subprojects/packagefiles/dav1d/0001.patch delete mode 100644 subprojects/packagefiles/dav1d/src/meson.build create mode 100644 subprojects/packagefiles/ffmpeg/0001.patch delete mode 100644 subprojects/packagefiles/ffmpeg/meson.build diff --git a/meson.build b/meson.build index 3f2c3b05ed..47e33455a0 100644 --- a/meson.build +++ b/meson.build @@ -1,6 +1,6 @@ project('Aegisub', ['c', 'cpp'], license: 'BSD-3-Clause', - meson_version: '>=0.57.0', + meson_version: '>=1.0.0', default_options: ['cpp_std=c++14', 'buildtype=debugoptimized'], version: '3.2.2') diff --git a/subprojects/dav1d.wrap b/subprojects/dav1d.wrap index 49251c463e..2dc6bfc6df 100644 --- a/subprojects/dav1d.wrap +++ b/subprojects/dav1d.wrap @@ -1,8 +1,8 @@ [wrap-git] directory = dav1d url = https://github.com/videolan/dav1d.git -revision = 0.9.2 -patch_directory = dav1d +revision = head +diff_files = dav1d/0001.patch [provide] dav1d = dav1d_dep diff --git a/subprojects/ffmpeg.wrap b/subprojects/ffmpeg.wrap index e03e121231..3d2a60e893 100644 --- a/subprojects/ffmpeg.wrap +++ b/subprojects/ffmpeg.wrap @@ -1,8 +1,8 @@ [wrap-git] directory = ffmpeg url = https://gitlab.freedesktop.org/gstreamer/meson-ports/ffmpeg.git -revision = c7a42b33c46c7b52f5e5c908e78bc411555aac1f -patch_directory = ffmpeg +revision = head +diff_files = ffmpeg/0001.patch [provide] libavformat = libavformat_dep diff --git a/subprojects/packagefiles/dav1d/0001.patch b/subprojects/packagefiles/dav1d/0001.patch new file mode 100644 index 0000000000..5356fa5e29 --- /dev/null +++ b/subprojects/packagefiles/dav1d/0001.patch @@ -0,0 +1,39 @@ +diff --git a/include/dav1d/dav1d.h b/include/dav1d/dav1d.h +index e8f0705..ff48ea0 100644 +--- a/include/dav1d/dav1d.h ++++ b/include/dav1d/dav1d.h +@@ -34,7 +34,7 @@ + #include "common.h" + #include "picture.h" + #include "data.h" +-#include "version.h" ++#include "dav1d_version.h" + + #ifdef __cplusplus + extern "C" { +diff --git a/include/dav1d/meson.build b/include/dav1d/meson.build +index 68faaf9..09b0239 100644 +--- a/include/dav1d/meson.build ++++ b/include/dav1d/meson.build +@@ -28,7 +28,7 @@ version_h_data.set('DAV1D_API_VERSION_MAJOR', dav1d_api_version_major) + version_h_data.set('DAV1D_API_VERSION_MINOR', dav1d_api_version_minor) + version_h_data.set('DAV1D_API_VERSION_PATCH', dav1d_api_version_revision) + version_h_target = configure_file(input: 'version.h.in', +- output: 'version.h', ++ output: 'dav1d_version.h', + configuration: version_h_data) + + dav1d_api_headers = [ +diff --git a/src/meson.build b/src/meson.build +index 3a34e76..53ef660 100644 +--- a/src/meson.build ++++ b/src/meson.build +@@ -335,7 +335,7 @@ libdav1d = library('dav1d', + ) + + dav1d_dep = declare_dependency(link_with: libdav1d, +- include_directories : include_directories('../include/dav1d') ++ include_directories : include_directories('../include/', '../include/dav1d/') + ) + + # diff --git a/subprojects/packagefiles/dav1d/src/meson.build b/subprojects/packagefiles/dav1d/src/meson.build deleted file mode 100644 index 6886c775f0..0000000000 --- a/subprojects/packagefiles/dav1d/src/meson.build +++ /dev/null @@ -1,366 +0,0 @@ -# Copyright © 2018-2019, VideoLAN and dav1d authors -# All rights reserved. -# -# Redistribution and use in source and binary forms, with or without -# modification, are permitted provided that the following conditions are met: -# -# 1.
