GodotVideoPlayer

项目设置

• 项目描述
• 版本号
• 使用自定义用户目录：方便看日志
  • use custom user dir
  • custom user dir name
• 视口：1920x1080
• 禁用垂直同步。播放视频时帧率能更高。
• ClearColor：改为纯黑
• Debug->File Logging->Enable File logging 开

设置gdextension

流程

1. git submodule add -b 4.2 https://github.com/godotengine/godot-cpp gd_extensions/godot_cpp 添加子模块，版本需要对应
2. Sconstruct
3. build.py
4. gozen.gdextension
5. 插件编写

# Sconstruct
import os

env = SConscript("../godot_cpp/SConstruct")
env.Append(CPPPATH=['src'])
dest_dir = "../../src/bin/gozen/"

num_jobs = ARGUMENTS.get('jobs', 16)
platform = ARGUMENTS.get('platform', 'windows')

src = Glob("src/*.cpp")
libpath = '{}libgozen{}{}'.format(dest_dir, env['suffix'], env['SHLIBSUFFIX'])
shardlib = env.SharedLibrary(libpath, src)

Default(shardlib)

#  build.py
import os

os.chdir("gd_extensions/gozen")
os.system("scons -j 16 target=template_debug")
os.chdir("../..")

[configuration]

entry_symbol = "gozen_library_init"
compatibility_minimum = 4.2
reloadable = true # 热更新dll

[libraries]

windows.debug.x86_64 = "res://bin/gozen/libgozen.windows.template_debug.x86_64.dll"
windows.release.x86_64 = "res://bin/gozen/libgozen.windows.template_release.x86_64.dll"

6.1 API 文档

git submodule add -b release/6.1 https://github.com/FFmpeg/FFmpeg gd_extensions/gozen/ffmpeg

注

移动git子模块，使用git mv
git mv gd_extensions/gozen/ffmpeg other/ffmpeg
