I think this header file is for int32_t? consider using ppapi/c/pp_stdint.h
instead.

Done.

Reverted. It's for PPAPI_SHARED_EXPORT.

+#include "ppapi/shared_impl/ppapi_shared_export.h"
+
+namespace ppapi {
+
+class PPAPI_SHARED_EXPORT MediaStreamAudioTrackShared {
+ public:
+  struct Attributes {
+    Attributes()
+        : buffers(0) {}

[Peng, 2014/05/27 14:35:49]

It can be fit into one line.

[thembrown, 2014/05/27 17:11:23]

Done.
