Description
Hi
Summary of the bug:
For some unit tests on a project I ended up seeing different results when decoding a constant gray sample video from mpeg4 to rgb24 depending if I'm on macOS x86_64 or arm64.
I generated the sample video sample_gray_100.avi from a constant gray value RGB[100,100,100] (0x646464 in hex). I first confirmed that playing the video on VLC for both architectures display the same correct output of the expected constant gray 0x646464 value.
Here is how to reproduce, testing on a single gray frame of size 2x2:
% ffmpeg -v 9 -loglevel 99 -i sample_gray_100.avi -vf select='eq(n\,1)',showinfo -f rawvideo -pix_fmt rgb24 -sws_flags print_info - | hexdump
Below are the two outputs on macOS x86_64 and arm64
macOS x86_64:

I can see that for both archs the frame YUV value is the same [102 128 128], but the RGB output differs: on x86_64 I get the expected 0x64 values, but 0x62 on arm64. I also confirmed the "wrong" behaviour on arm64 is observed on both n6.0 and n6.1-dev
The default chosen swscale converter for the 2 archs seems different, but are these results above normal/expected ?
Also, reading this answer, adding full_chroma_int+accurate_rnd to the swscale options fix the output to the right 0x64 gray value on arm64, but this is not the default behaviour.
P.S: Could this be related to #979 ?

generated the sample video sample_gray_100.avi from a constant gray value RGB[100,100,100] (0x646464 in hex).
You need 10 bit YCbCr to preserve 8 bit RGB.
confirmed that playing the video on VLC for both architectures display the same correct output of the expected constant gray 0x646464 value.
You cannot. VLC has a lot of bugs, that makes tbis impossible. You need to use mpv.
can see that for both archs the frame YUV value is the same [102 128 128]
It is 420, not 444. So how can it be, not all pixels have all components? But sure, 102 will decode to 100 in full RGB.
P.S: Could this be related to #979 ?
No, that happens on with bgr from 420 and vice versa. Here we have rgb, not bgr.
full_chroma_int+accurate_rnd
Does only accurate_rnd fixes it?
comment:2 by , 10 months ago
I tried mpv on both x86_64 and arm64 and the displayed RGB value is to be [101 100 100] (checking on the frame with Apple digital color meter if that matters).
No, using accurate_rnd only does not fix it. (neither does using full_chroma_int only)
