Incorrect color when decoding h264 file

[iss]

Summary of the bug:
When converting attached file, colors are different to what I see when I play it with ffplay. Ffplay displays correct colors.

This has been reported to us as a bug, but I don't see any obvious issue in our code and I get same result when converting to png file. So I figured this could be ffmpeg bug.

How to reproduce:

% ffmpeg -i incorrect_color_h264.mp4 -frames 1 out.png
% ffplay incorrect_color_h264.mp4

Full console output:

$ ./ffmpeg.exe  -v 9 -loglevel 99 -i incorrect_color_h264.mp4 -frames 0  out.png

Actual result

[Carl Eugen Hoyos]

It appears to me that ffplay shows wrong colours but ffmpeg creates a correct output: Why do you think the expected_result.png file is correct / how did you produce it?

[iss]

Replying to cehoyos:

It appears to me that ffplay shows wrong colours but ffmpeg creates a correct output: Why do you think the expected_result.png file is correct / how did you produce it?

I think that expected result is correct, because it shows correct in most players I tested (web browser, VLC, ffplay, even windows thumbnail looks like expected_result.png)

Unfortunately I can't tell how the file was created, it was provided as sample for bug report - see ​https://developer.blender.org/T81307

Perhaps not quite useful information is, that I have converted pFrame buffer data to RGB (I did this manually for 2 pixels) and the darker color was different to either of those results. There is good chance I did not do this correctly though, I am not used to other pixel formats than our RGBA.

This was my sample for darker pixel:

pFrame->data[0][100]
pFrame->data[1][100]
pFrame->data[2][100]

And lighter pixel:

pFrame->data[0][0]
pFrame->data[1][0]
pFrame->data[2][0]

I used this util to convert values ​https://www.mikekohn.net/file_formats/yuv_rgb_converter.php

[Balling]

web browser, VLC, ffplay,

This is not true. thumbnail is actually actual_result.png.

We've recorded the pattern video with OBS Studio (recording program) from our display.

This was our first post.
​https://blenderartists.org/t/big-color-problem-with-video-editing/

This was our second post.
​https://developer.blender.org/T81307

We've contacted four days ago Prof. Dr.-Ing. Jörn Ostermann at ​https://www.mpegstandards.org for this color problem. Unfortunately couldn't help much.

[Carl Eugen Hoyos]

Replying to 3DLight:

We've recorded the pattern video with OBS Studio (recording program) from our display.

But you don't have a YUV420 display, do you?

Note that all information has to be posted here in the ticket (except for large sample files), please do not use other external resources.

From a quick look, the attached file does not contain the necessary information to decide how it should be displayed: Given that you apparently control the input file, why don't you add the missing information when creating the file?

[3DLight]

Do you mean color format with YUV420 display?
Our Display:
Bit depth: 8-bit
Color format: RGB
Color space: Standard dynamic range (SDR)

Here is another user who tested this:

Quote: "It’s like the color management of video files (mp4 files at least) is broken."

[Carl Eugen Hoyos]

Replying to 3DLight:

Color format: RGB

Then why are you recording in yuv420?

Please run ffmpeg -i on any mp4 file you find and compare with the attached input file: You will see that most files contain information about the colourspace that is missing from the file you created.

[3DLight]

We don't know why it's missing. We don't have that know-how for this.

[Balling]

We don't know why it's missing. We don't have that know-how for this.

read this ​https://trac.ffmpeg.org/wiki/colorspace

[Balling]

Well, because it is 1920x1080, it is automatically promoted to BT.709 and limited range. But not in ffmpeg.
So, use ffmpeg -i incorrect_color_h264.mp4 -c copy -colorspace bt709 -color_primaries bt709 -color_trc bt709 out.mp4 to set all the stuff and then when you will do out.png it will be good.

Thanks for looking into this and sorry for wasting your time. Next time I will try to do more research, but I was out of ideas this time.
