為 Mac OSX High Sierra 10.13 編譯 ffmpeg

Question

Hello I made an electron app that uses ffmpeg to combine audio and renders video, it works fine on windows, linux, and modern mac osx computers, but a user has reported to me that on an older version of mac osx such as High Sierra 10.13 ，我設置 ffmpeg 的方式不起作用。

我有一個帶有 High Sierra v10.13 的虛擬機，我從我的RenderTune 發布頁面安裝RenderTune-mac.dmg ，然后我從這個鏈接下載 2 個音頻文件和圖像。 我打開 RenderTune，然后嘗試渲染視頻。 我將音頻文件組合成單個 mp3 的命令工作正常，但是當我嘗試將該 mp3 與圖像文件組合時，我與 electron 應用程序打包的 ffmpeg 構建失敗並出現此錯誤：

這些文件將在 windows/linux 和最近的 mac 版本上正常呈現。 為了在 Mac 計算機上的 electron 應用程序中使用 package ffmpeg，我必須構建一個沒有動態鏈接庫的自定義沙盒版本。 我有一個 .sh 文件，它會自動下載 ffmpeg 並使用 mac 計算機的所有必要標志構建它。 https://github.com/MartinBarker/RenderTune/blob/master/buildffmpeg.sh在this.sh文件中是我使用這些標志編譯ffmpeg的地方：

./configure \
    --pkgconfigdir="$WORKSPACE/lib/pkgconfig" \
    --prefix=${WORKSPACE} \
    --pkg-config-flags="--static" \
    --extra-cflags="-I$WORKSPACE/include -mmacosx-version-min=${MACOS_MIN}" \
    --extra-ldflags="-L$WORKSPACE/lib -mmacosx-version-min=${MACOS_MIN}" \
    --extra-libs="-lpthread -lm" \
        --enable-static \
        --disable-securetransport \
        --disable-debug \
        --disable-shared \
        --disable-ffplay \
        --disable-lzma \
        --disable-doc \
        --enable-version3 \
        --enable-pthreads \
        --enable-runtime-cpudetect \
        --enable-avfilter \
        --enable-filters \
        --disable-libxcb \
        --enable-gpl \
        --enable-nonfree \
        --disable-libass \
        --enable-libfdk-aac \
        --enable-libmp3lame \
        --enable-libx264 

如果我嘗試在我的 High Sierra VM 中運行此腳本，則會失敗並顯示以下消息：

Unknown option "-extra-libs=-lpthread"

如果我刪除該標志，它會失敗並顯示不同的消息：

Unknown option "--enable-static"

我需要這個標志才能在 mac Apple Store 上發布我的 electron 應用程序，誰能幫我編譯 ffmpeg 的 static 版本？13 適用於現代 macos 1 等舊版本。

Answer 1

如果您支持多個操作系統及其各種版本，您將需要多個版本。 我通過編譯AdoptOpenJDK然后編譯FFmpeg 2.8在 High Sierra 10.13 上成功編譯了 FFmpeg 。 我手動使用自制軟件，現在將自動使用網絡請求下載 static 版本。
