x265 encoder generate wrong PTS/DTS and incorrect result

On git master, with the following sout configuration

./vlc ~/Desktop/\[PuyaSubs\!\]\ Uchuu\ Patrol\ Luluco\ -\ 10\ \[720p\]\[967D0521\].mkv \
    --dec-dev=none -I dummy -vv \
     --run-time=10 --play-and-exit \
     --sout="#transcode{vcodec=h265}:std{access=file,dst=foo.mkv}"

the muxer generate error message

[matroska @ 0x61b00007fc80] pts (4423) < dts (4444) in stream 1
[000060d00002a510] avformat mux error: could not write frame (pts: 4423305, dts: 4444581) (pkt pts: 4423, dts: 4444)
[matroska @ 0x61b00007fc80] pts (4636) < dts (4657) in stream 1

and the video is much faster than the original.

There is no issue when subsituting h264 to h265 in the command line.
