//編輯保存時間並參考SF project。 IMO,可能以後更多的工作,節省起牀到速度的工作噸.....ffmpeg for android build - 是否完整
在這個問題上:
添加一個git project
構建更容易定製的工具鏈安裝,以便你可以從ndk-build
樣品標準輸出 - 最初使用的Ubuntu 12.04中在Windows Vista上vmplayer。 IMO的Linux比cygwin更適合構建。
我遵循這些instructions得到一個不確定的結果,其中存在以下條件。
build_android.sh似乎正常退出
的config.log有錯誤的位置,確認從crosstoolchain
GCC所有靜態庫是建立好的 (./libavfilter,./libavcodec等)
ffmpeg.o在那裏,執行確定
沒有./android目錄按前綴設置配置
它看起來像我可以只是把二進制文件到我的手機和測試的外殼。如果沒關係,那麼我可以看一下靜態庫的jni包裝。
但爲什麼沒有寫入任何東西--prefix =。/ android/armv7-a ??
配置記錄的內容進行處理: 這條道路並不在構建結束

謝謝..會給這個嘗試 –
嘿它爲我工作。但同時我得到了一些警告dat datat某些函數已被棄用,並且「libavcodec/aacps.c:352:9:警告:從不兼容指針類型[默認啓用]傳遞'hybrid4_8_12_cx'的參數libavcodec/aacps.c:331: 13:注意:期望'const float(*)[8] [2]',但參數的類型是'float(*)[8] [2]' 「。我應該忽略它嗎? –
該死的,我必須從extra-cflags中除去「-DANDROID」以外的所有內容,並且.mak文件的問題得到解決。謝謝。 –
