+## Media Testing ##

+#### MetaDataUtils Test
+The MetaDataUtils Unit Test Suite validates the libstagefright_metadatautils library available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+m MetaDataUtilsTest
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/MetaDataUtilsTest/MetaDataUtilsTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/MetaDataUtilsTest/MetaDataUtilsTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/tests/metadatautils/MetaDataUtilsTestRes-1.0.zip). Download, unzip and push these files into device for testing.
+
+```
+adb push MetaDataUtilsTestRes-1.0 /data/local/tmp/
+```
+
+usage: MetaDataUtilsTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/MetaDataUtilsTest -P /data/local/tmp/MetaDataUtilsTestRes-1.0/
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest MetaDataUtilsTest -- --enable-module-dynamic-download=true
+```
