The resulting colors are washed out, i.e. blacks become lighter. Probably something to do with the color range?

Is the issue also reproducible with `ffplay`? `ffplay` plays `input.mp4` with the same washed out colors of `output.mp4`.
Is the issue also reproducible if you re-encode the output file to h.264? Yes, h.264->h.265->h.264 shows same results as only encoding to h.265.
Please provide an input file. Following the instructions on wiki:WikiStart I uploaded it to the VideoLAN File Uploader, with description `"input.mp4" file for ffmpeg ticket #7180`, called `ticket_7180_input.mp4` and has 19,707,503 bytes. I hope
I'm now thinking that it could be a player problem, but what I don't understand is why `input.mp4` has normal colors in VLC/MPC-HC but not in `output.mp4`. Although... now I'm starting to think that the washed out colors might be the normal ones and VLC/MPC-HC are reading something wrong in `input.mp4` that somehow ffmpeg fixes...? I don't know anymore. that works for you. If not, please tell me and I'll find another way. -- Ticket URL: <https://trac.ffmpeg.org/ticket/7180#comment:2> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

Do I understand correctly that if there is a bug then it is not related to H.265 encoding but to the decoding of your input sample? -- Ticket URL: <https://trac.ffmpeg.org/ticket/7180#comment:3> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

Do I understand correctly that if there is a bug then it is not related to H.265 encoding but to the decoding of your input sample? My initial guess was something to do with H.265 because if I reencoded the file from H.264 to H.264 the colors didn't change. However, a bug related to the decoding also might make sense. But I'm afraid I don't have the knowledge to answer that question, I'm sorry.
Replying to [comment:4 cehoyos]:
I forgot: How did you create the input sample? I just removed the audio because it was not relevant and saved some size: `ffmpeg -i input.mp4 -c:v copy -an`. I don't have info about the creation of the original `input.mp4`, it seemingly was created with `ffmpeg` but I don't know more about it. Before that, it originally came from a DSLR camera, probably a Canon EOS 7D.

Gray or black? What colour is the right "under-sleeve" of the man with the laptop and the white "over-shirt" supposed to be? Green or black-green? Looking at the red car on the right and the red (Hello Kitty?) logo on the left and the green logo in the middle of the screen, I suspect that the "washed out" colours are actually correct. And please look at the faces! I'll attach two png files: Is `washed.png` what you see after re-encoding with FFmpeg and is `dark.png` what you originally expected? -- Ticket URL: <https://trac.ffmpeg.org/ticket/7180#comment:7> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

Both colors were identical to `washed.png`, while MPC-HC and VLC showed it like `dark.png`. So it was a subjective thing on my part and 'washed out' colors have to be the good ones, like you suspected. It was a player issue with the original file then!
