fixed a bug of context overwritten by key frame recoding The recoding loop save and restore frame coding context for recodes. However in recoding of key frames, some of the coding context saved was stale from last encoded inter frame. The save/restore sometimes overwrites the re-inintialized coding context with saved context from last frame, resulting in encoder/decoder mismatch Change-Id: I354ae2f71074d142602d51d06544c05a2462caaf
