The patchset works (tested on a Nexus5x and Galaxy S7). I have one more comment regarding the AVMediaCodecDeviceContext surface field. The documentation should probably say something about the fact that if the user pass a local reference, the hw context and codec initialization must be done in the same thread (otherwise it will crash). Also, whether it is a local or global reference, the hw context does not take the reference ownership. Unless we do the same thing as in av_mediacodec_default_init (ie: make a global reference) but that would require to expose lavcodec/ffjni to lavutil.
