Missing video - Codec ID 0x00000000 Basic Windows bitmap format

[456325]

Summary of the bug:
I have noticed that certain file converted is showing a black screen during playback, but audio is played. Mediainfo shows:

Video
ID                                       : 0
Format                                   : RGB
Codec ID                                 : 0x00000000
Codec ID/Info                            : Basic Windows bitmap format. 1, 4 and 8 bpp versions are palettised. 16, 24 and 32bpp contain raw RGB samples

Command used:
ffmpeg -loglevel debug -i "sample.avi" -vf format=nv12 -c:a copy -c:v libx265 -qp 25 -map "" "output.avi"

result/output:
​https://bin.disroot.org/?c577c297b593e3c8#2Eu3GV5dQgzX2mGmLK6UhWWkd9vHhmpkZa8m1YXDvk1W

Sample file (valid file, please use as an ffmpeg input to get erroneous file):
​https://ufile.io/nf30mvxw

Can anyone please try to reproduce using that command with that file?

I don't think this is a valid ticket, the input file plays fine here and hevc encoding is used widely.
For future tickets or if you want to reopen this one: Please test current FFmpeg git head, the only version supported on this bug tracker, always paste the complete, uncut console output into the ticket, do not store the console output on another website and explain why you believe anything went wrong - I do not easily remember a ticket where MediaInfo output helped avoiding this explanation, MediaInfo output is generally not useful to report FFmpeg bugs.

Probably a duplicate of ticket #8362, difficult to guess.

Replying to Carl Eugen Hoyos:

the input file plays fine here

i thought it was obvious from my description, that the sample file is input and correct, but the output file (produced by mentioned command) is wrong, and that i wish someone try to do. Download the file please and run the command mentioned. Thank you

Then yes, a duplicate of #8362
