 Summary of the bug:
 I use rtp as h265 transport and found that even with 1% of packets loss
 image became totally distorted (static background became gray and only
 moving parts are shown). It seems that avdec_h265 (based on libav) has a
 bug because if I use NVidia HW decoder nvh265dec it decode that same
 stream without any visible artifacts. I've tried to play such file (1%
 loss) with ffplay and found that the problem is inside ffmpeg.

 How to reproduce:
 {{{
 % ffplay h265_0.01_loss.mkv
 ffplay version 5.1.3-1 Copyright (c) 2003-2022 the FFmpeg developers
   built with gcc 12 (Debian 12.2.0-14)
 }}}

 If I do the same (1% loss) for h264 codec no such problem occured.
