Hello,

I just got some trouble while using the function VideoWriter to generate a video. I'm trying to use the sample code in the function document, as below.

clear
clc
A = rand(300);
v = VideoWriter("newfile.avi");
open(v)
writeVideo(v,A)
close(v)

These lines can run without any error message, and a video file is created. However, the created video file cannot be played by windows media player.

In fact, I had used this function on another computer and it works well. Is the function VideoWriter or any related function environment-dependent? The computer where I got problem is run on windows 11, and I'm using Matlab 2023b.

Thanks for any help.

Moreover, I just checked play the file through another player (VLC). It can be played correctly through VLC. However, I want to insert the video file into a .pptx file. The video is still not able to be played in the .pptx file. It seems that there are indeed some issues with this video file。
