Comment (by SuRGeoNix):
Found another issue with HEVC (at least with the same LG Chess 4K Demo.ts)
that might be related to this one.
I have implemented a reverse playback by decoding from keyframe until the
next one and then seeking to the previous keyframe (Manually ensuring that
I actually have keyframe to keyframe).
While decoding I'm draining the decoder properly but it seems that
sometimes it misses some frames and I have at least 2-3 frames diff
between the last draining frame and the next keyframe. I will do further
testing and open a new issue if required.
