When you rebase, we have removed the variable "codec" from this method, and just
"return proc(...)" instead of calling "codec.reset(proc(...))". We'll be
guaranteed to have a stream, so you can skip this if statement.

Sorry, as I am not really using git before, I have a dummy question:
how can I "rebase"? I tried "git rebase", and did not see any changes.
could you let me know how can I "sync" my current CL correctly with the head of
skia?

Thanks for the tips. I got the code rebase and fixed the code here.

+            SkASSERT(!codec);
+            codec.reset(SkRawCodec::NewFromStream(streamDeleter.detach()));
+        }
+#endif
     }
