From: Matthieu Bouron<matthieu.bou...@stupeflix.com>If a JNI environment is not already attached to the thread where the MediaCodec calls are made the current implementation will attach / detach an environment for each MediaCodec call wasting some CPU time. ff_jni_get_env replaces ff_jni_{attach,detach} by permanently attaching an environment (if it is not already the case) to the current thread. The environment will be automatically detached at the thread destruction using a pthread_key callback. Saves around 5% of CPU time (out of 20%) while decoding a stream with MediaCodec. --- libavcodec/ffjni.c | 43 +++++---- libavcodec/ffjni.h | 15 +--
