+// TODO(hbos): This is essentially a copy of an decoder class in WebRTC that as
+// of this statement has not yet landed, but that I want to have accessible in
+// Chromium before that CL lands. This is because I use it in order to validate
+// the build files for OpenH264 and the WebRTC encoder/decoder CL cannot land
+// until I can build OpenH264 from source. Once the build files are stable I
+// will land both CLs and remove this copy of the decoder.
