There are two patches on the development mailing list, waiting for
review and to be applied to ffmpeg master:
http://ffmpeg.org/pipermail/ffmpeg-devel/2017-June/212956.html
http://ffmpeg.org/pipermail/ffmpeg-devel/2017-June/212956.html

These may or may not make it to ffmpeg HEAD really soon.

In the meantime, you can apply them to your local build (are you
building yourself?) and see whether they help you.
