Since you're not compiling webm_stream_parser.cc for Android, it might be better
to just add this file to the 'sources not to build' list in media/media.gyp for
now. 

In the future we should probably add a USES_FFMPEG type define for this sort of
thing instead of an OS specific one. When that day comes the padding for the
non-FFmpeg case will be 0 because this is only here because FFmpeg expects it.

-  scoped_array<uint8> buf(new uint8[size + FF_INPUT_BUFFER_PADDING_SIZE]);
+  scoped_array<uint8> buf(new uint8[size + INPUT_BUFFER_PADDING_SIZE]);
   memcpy(buf.get(), data, size);
-  memset(buf.get() + size, 0, FF_INPUT_BUFFER_PADDING_SIZE);
+  memset(buf.get() + size, 0, INPUT_BUFFER_PADDING_SIZE);
   return new DataBuffer(buf.Pass(), size);
