-// the video from the reference files located in GetReferenceFilesDir().
-// The file kReferenceY4mFileName.kY4mFileExtension is played using a
-// FileVideoCaptureDevice and its sibling with kYuvFileExtension is used for
-// comparison.
-//
-// You must also compile the chromium_builder_webrtc target before you run this
-// test to get all the tools built.
-//
-// The external compare_videos.py script also depends on two external
-// executables which must be located in the PATH when running this test.
-// * zxing (see the CPP version at https://code.google.com/p/zxing)
-// * ffmpeg 0.11.1 or compatible version (see http://www.ffmpeg.org)
-//
-// The test runs several custom binaries - rgba_to_i420 converter and
-// frame_analyzer. Both tools can be found under third_party/webrtc/tools. The
-// test also runs a stand alone Python implementation of a WebSocket server
-// (pywebsocket) and a barcode_decoder script.
