Hi,
> So its better to use that instead of human written assembly? Does clang generate faster code without this asm?
I'm not sure I fully understand your questions, but I hope the following answers it. The reason why we auto-converted our intrinsics code to asm is not a technical one, we unfortunately just don't have the knowledge or resources to manually write asm code. If I remember correctly, the SIMD optimized code runs about twice as fast as the C code, especially on UHD input.

Done, please find attached a second version (v1) of the XPSNR avfilter patch.
Thanks and best,

So its better to use that instead of human written assembly?
Does clang generate faster code without this asm?

Please remove SLICE_THREADS related flag as there is no call to
execute to filter in slices.
Please remove stdbool.h header and adapt code to compile without it.

+
+Obtain the average (across all input frames) and minimum (across all color plane averages)
+eXtended Perceptually weighted peak Signal-to-Noise Ratio (XPSNR) between two input videos.
+
+The XPSNR is a low-complexity psychovisually motivated distortion measurement algorithm for
+assessing the difference between two video streams or images. This is especially useful for
+objectively quantifying the distortions caused by video and image codecs, as an alternative
+to a formal subjective test. The logarithmic XPSNR output values are in a similar range as
+those of traditional @ref{psnr} assessments but better reflect human impressions of visual
+coding quality. More details on the XPSNR measure, which essentially represents a blockwise
+weighted variant of the PSNR measure, can be found in the following freely available papers:
+
+@itemize
+@item
+C. R. Helmrich, M. Siekmann, S. Becker, S. Bosse, D. Marpe, and T. Wiegand, "XPSNR: A
+Low-Complexity Extension of the Perceptually Weighted Peak Signal-to-Noise Ratio for
+High-Resolution Video Quality Assessment," in Proc. IEEE Int. Conf. Acoustics, Speech,
+Sig. Process. (ICASSP), virt./online, May 2020. @url{www.ecodis.de/xpsnr.htm}

+C. R. Helmrich, S. Bosse, H. Schwarz, D. Marpe, and T. Wiegand, "A Study of the
+Extended Perceptually Weighted Peak Signal-to-Noise Ratio (XPSNR) for Video Compression
+with Different Resolutions and Bit Depths," ITU Journal: ICT Discoveries, vol. 3, no.

+@end itemize
+
+When publishing the results of XPSNR assessments obtained using, e.g., this FFmpeg filter, a
+reference to the above papers as a means of documentation is strongly encouraged. The filter
+requires two input videos. The first input is considered a (usually not distorted) reference
+source and is passed unchanged to the output, whereas the second input is a (distorted) test
+signal. Except for the bit depth, these two video inputs must have the same pixel format. In
+addition, for best performance, both compared input videos should be in YCbCr color format.
+
+The obtained overall XPSNR values mentioned above are printed through the logging system. In
+case of input with multiple color planes, we suggest reporting of the minimum XPSNR average.
+
+The following parameter, which behaves like the one for the @ref{psnr} filter, is accepted:
+
+@table @option
+@item stats_file, f
+If specified, the filter will use the named file to save the XPSNR value of each individual
+frame and color plane. When the file name equals "-", that data is sent to standard output.
+@end table
+
+This filter also supports the @ref{framesync} options.
+
+@subsection Examples
+@itemize
+@item
+XPSNR analysis of two 1080p HD videos, ref_source.yuv and test_video.yuv, both at 24 frames
+per second, with color format 4:2:0, bit depth 8, and output of a logfile named "xpsnr.log":
