This should not be needed unless it fixes a crash.
NewGlobalRef/DeleteGlobalRef (as well as NewLocalRef/DeleteLocalRef)
handles NULL pointers. The JNI MediaCodec wrapper is missleading about
this as it does this kind of unneeded checks everywhere (I did not known
at the time that the ref functions handle NULL). I have a local branch
cleaning this up. I will submit it to the ML in the upcoming days.
