When including pdf's which contain a jpg image, one currently get with pdflatex a pdf error in the terminal.

To reproduce the problem:

Create a pdf named pdfmitjpg with an embeded jpg:

% jobname= pdfmitjpg
\documentclass{article}
\usepackage{graphicx}
\begin{document}
\includegraphics{example-image.jpg}
\end{document}

Include this pdf in another document:

\documentclass{article}
\usepackage{graphicx}
\begin{document}
\includegraphics{pdfmitjpg}
\end{document}

On the terminal I can then see

 Syntax Error (441): Unknown filter 'DCTDecode'

If the first pdf is compiled with the

     \pdfcompresslevel0
     \pdfobjcompresslevel0

then the error number change to 418.

The pdf itself looks fine. It open in adobe and sumatra. In texlive there is no such error message.

Thanks, I have fixed this (luatex and xetex were also affected).

I had the same problem and fixed it!

Windows search > MiKTex Update > Select 'I want to get packages from a remote package repository' and 'Use the nearest package repository' > Click 'Next' > Select al the updateable packages and click 'Next'.

This should do the trick!
