qt_add_ios_ffmpeg_libraries

Auxiliary function which embeds FFmpeg binaries in iOS app bundle.

This command was introduced in Qt 6.8.

注意： This command is in technology preview and may change in future releases.

概要

qt_add_ios_ffmpeg_libraries(target)

若无版本命令被禁用，使用 qt6_add_ios_ffmpeg_libraries() 代替。它支持如此命令的一组相同自变量。

描述

FFmpeg binaries from the online installer must be embedded into the application's bundle. To embed FFmpeg binaries, you can add the qt_add_ios_ffmpeg_libraries command to the app's CMakeLists.txt file.

This command will set several properties for the application target:

XCODE_EMBED_FRAMEWORKS, adds the informatioin for XCode (which FFmpeg binaries to embed).
XCODE_EMBED_FRAMEWORKS_CODE_SIGN_ON_COPY is set to ON, so that the embedded FFmpeg binaries will be code-signed.
XCODE_ATTRIBUTE_LD_RUNPATH_SEARCH_PATHS - to add the location of embedded FFmpeg libraries within the bundle.

If code-signing is not required, you can use the QT_NO_FFMPEG_XCODE_EMBED_FRAMEWORKS_CODE_SIGN_ON_COPY variable before the command qt_add_ios_ffmpeg_libraries :

set(QT_NO_FFMPEG_XCODE_EMBED_FRAMEWORKS_CODE_SIGN_ON_COPY ON)

注意： qt_add_ios_ffmpeg_libraries requires CMake 3.28 or later.
