RTSP h265 input produces invalid MP4 output with -c copy

Description

Summary of the bug:

Taking a RTSP HEVC main profile input from a HikVision IP PTZ camera, and producing an mp4 with -c copy, results in an invalid mp4 file.

Reading this mp4 file results in the following errors:

[AVBSFContext @ 0x55f87e9a1f00] No start code is found.
/tmp/test3.mp4: Invalid data found when processing input

VLC, mpv and ffmpeg are all unable to read the file, despite all being able to play the stream live without problem. However, if one outputs to a TS file, the output is entirely usable, and can afterwards be remuxed to mp4 without issue.

The issue seems identical to this mailing list post from 2017, which unfortunately had no followup: https://ffmpeg.org/pipermail/libav-user/2017-November/010762.html.

How to reproduce:

I have uploaded the mp4/ts files using the videolan file uploader (​https://streams.videolan.org/upload/#)
