* commit '54dd9b1cdd9e54f1ee39ae25af0324f8aba2831b':
h264: set mb_aff_frame in frame_start()
h264: move the block starting a new field out of slice_header_parse()
Both commits are merged at the same time in order to prevent a
regression with Ticket #4440 (see 38660128).

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.
The accessors are needed only from outside libavutil.

It's a small and simple function that can be inlined.
This removes one private symbol and should reduce object dependencies with the next
major bump

lavc/movenc rely on avpriv_dnxhd_parse_header_prefix declared by
dnxhddata.h since e47981dab7.
Fixes a missing symbol error in lavc/movenc if the dnxhd encoder is not
enabled.
This reverts commit d30cf57a7b, reversing changes made to
acc155ac55. The commit d30cf57a7b
provided irrelevant code complexity and decoding slowdown. But the main disadvantage of this
commit is a decoder crash. So it should be reverted.

There is actually a need for the origin and end point not to be defined.
We can not automatically insert them with the y value of the first and
last point as it will influence the curves in a wrong way.
Fixes#5397
If this still doesnt give the same results on all platforms then this should be
disabled

Fix const corectness and zero init the struct. This example code would actually crash when initializing string.

When seeking a file where codec delay is greater than 0, the timecode
can become negative after offsetting by the codec delay. Failing to cast
to a signed int64 will cause the check against skip_to_timecode to evaluate
true for these negative values. This breaks the "skip_to" seek mechanism.
