Need a player for 265 videos in raw format

[dns]

The stationary video recorder produces video in raw format, the files are obtained with the extension h264
ffplay, vlc, mpv don't play the file.

Yeah. The file turns out to be h265. I rename it, but it makes no sense.

ffplay -f hevc -i "IP camera_02_20230913_06.00.00-07.00.00[H][@220f5][1].h265"

It plays, but rewinding still doesn't work and writes an error in the console:

[hevc @ 000001d85e347b80] Invalid NAL unit 0, skipping.
[NULL @ 000001d85d81eb40] Invalid NAL unit 0, skipping.
Last message repeated 6 times

But here's the catch, I had a player that showed it perfectly and rewinded the file. I lost it

Renamed to .h265 is played by mpc-hc or mpc-be.
But if you want rewind etc. the best option is mux it to .mkv with MkvToolNix, it create the needed indexes to play forward and backward.

I think I found that player (I searched for half a day).

Player page (https://www.polyvision.ru/po/dlya-windows/pleer-h.264)

It plays files beautifully and rewinding works great. But why, why does ffmpeg stumble?

At first I didn't realize that it was playing - until I saw the time code advancing.
mux it to .mkv
Looks to work just fine, including reversing (& even though it does spit out, Invalid NAL, messages).

ffmpeg -i xxx.h265 -c copy out.mkv
