+ * MediaSampleReader benchmark tests.
+ *
+ * How to run the benchmark:
+ *
+ * 1. Download the media assets from http://go/transcodingbenchmark and push the directory
+ *    ("TranscodingBenchmark") to /data/local/tmp.
+ *
+ * 2. Compile the benchmark and sync to device:
+ *      $ mm -j72 && adb sync
+ *
+ * 3. Run:
+ *      $ adb shell /data/nativetest64/MediaSampleReaderBenchmark/MediaSampleReaderBenchmark
