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