+## Media Testing ##

+
+#### Mpeg4H263Encoder :
+The Mpeg4H263Encoder Test Suite validates the Mpeg4 and H263 encoder available in libstagefright.
+Run the following steps to build the test suite:
+```
+m Mpeg4H263EncoderTest
+```
+
+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/Mpeg4H263EncoderTest/Mpeg4H263EncoderTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/Mpeg4H263EncoderTest/Mpeg4H263EncoderTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/codecs/m4v_h263/enc/test/Mpeg4H263Encoder.zip ) Download, unzip and push these files into device for testing.
+
+```
+adb push Mpeg4H263Encoder/. /data/local/tmp/
+```
+
+usage: Mpeg4H263EncoderTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/Mpeg4H263EncoderTest -P /data/local/tmp/
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest Mpeg4H263EncoderTest -- --enable-module-dynamic-download=true
+```
