Question

我正在尝试使用mac osx 10.8.5在Andriod Studio上构建Gstreamer教程示例5.

我已从https://github.com/jaroslavas/Gstreamer-Android-example
我已经从
我从https://gstreamer.freedesktop.org/data/pkg/android/1.8.0/下载了Gstreamer Android库gstreamer-1.0-android-arm-1.8.0

4.我编辑了local.properties - 设置SDK和NDK路径

我编辑了src / main / jni / Android.mk文件并将GSTREAMER_ROOT_ANDROID设置为我提取Gstreamer库的路径
我创建了一个gradle.properties文件，以便设置标志android.useDeprecatedNdk = true
我已添加：

sourceSets.main { jni.srcDirs = [] }

为了不让Android Studio覆盖.mk文件

运行。

Gradle控制台显示了几个

/bin/bash: i: command not found
make: [genstatic_armeabi] Error 127 (ignored)

以下是完整的控制台日志：

:app:ndkBuild FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:ndkBuild'.
> Process 'command '/Users/vincenzodigiovambattista/AndroidStudioProjects/android-ndk-r11c/ndk-build'' finished with non-zero exit value 2

有什么建议吗？

我知道为Android Studio构建gstreamer很痛苦，检查周围没有完整的指南用于此目的，我想用这篇文章创建一个！

Answer 1

首先，在已知问题的https://gstreamer.freedesktop.org/releases/1.8/下，您可以看到无法使用NDK r11进行构建。请改用NDK r10。

如果你得到同样的错误，请转到GStreamer包中的share / gst-android / ndk-build文件夹，然后查看gstreamer-1.0.mk文件。搜索genstatic _ $（TARGET_ARCH_ABI）。在那里，您将看到该命令的定义，并可以检查它是否有任何错误。

有了这个错误，bash基本上会告诉你在执行genstatic_armeabi命令时遇到了一个未知的命令“i”。

Answer 2

HOST_SED仅在 Windows平台上定义。

我们需要根据需要定义HOST_SED。

<强> gstreamer-1.0.mk

# Host tools
ifeq ($(HOST_OS),windows)
    HOST_SED := $(GSTREAMER_NDK_BUILD_PATH)/tools/windows/sed
    GSTREAMER_LD :=
else
    HOST_SED := sed //linux
endif

....

@$(HOST_ECHO) "GStreamer      : [GEN] => $(PRIV_C)"
@$(call host-mkdir,$(PRIV_B_DIR))
@$(call host-cp,$(PRIV_C_IN),$(PRIV_C))
@$(HOST_SED) -i "s/@PLUGINS_DECLARATION@/$(PRIV_P_D)/g" $(PRIV_C)
@$(HOST_SED) -i "s/@PLUGINS_REGISTRATION@/$(PRIV_P_R)/g" $(PRIV_C)
@$(HOST_SED) -i "s/@G_IO_MODULES_LOAD@/$(PRIV_G_L)/g" $(PRIV_C)
@$(HOST_SED) -i "s/@G_IO_MODULES_DECLARE@/$(PRIV_G_R)/g" $(PRIV_C)
