Andreas Rheinhardt	9cae7f9450	avcodec/zlib_wrapper: Add wrapper for deflateInit() The rationale is the same as for the wrappers for inflateInit(), although the case for it is admittedly not so strong because there are less users of deflateInit(). Also remove an unnecessary inclusion of config.h in libavformat/protocols.c in order to trigger a request for reconfigure (which is needed for CONFIG_DEFLATE_WRAPPER to take effect).

Andreas Rheinhardt	dd8a55cb3e	avcodec/zlib_wrapper: Add wrappers for zlib inflateInit, inflateEnd It is not documented to be safe to call inflateEnd() on a z_stream that has never been successfully been initialized by inflateInit(), but just zeroed. It just happens to work and several codecs rely on this (they have FF_CODEC_CAP_INIT_CLEANUP set and even call inflateEnd() when inflateInit() failed or has never been called). To avoid this, other codecs recorded whether their zstream has been initialized successfully or not. This commit adds wrappers for inflateInit() and inflateEnd() that do what these other codecs do; furthermore, they also take care of properly setting up the zstream before inflateInit() and emit an error message in case of error.

Matthieu Bouron	376d8fb2c5	lavc/ffjni: replace ff_jni_{attach,detach} with ff_jni_get_env 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.	9 years ago
