Problems Encountered When Running Examples
Describe the bug
Error in examples/video Directory
When running the example in the examples/video directory, the following error occurs:
# [pkg-config --cflags -- libavformat libavcodec libavutil libswresample libavutil libavformat libavcodec libswscale libavutil libavformat libavcodec libswscale libswscale libavformat libavcodec libavutil libswscale libavformat libavcodec libavutil libswscale libavutil libavformat libavcodec libavutil libavutil libavformat libavcodec libswscale libavutil libavformat libavcodec libswscale]
pkg-config: could not find package 'libavformat'
This error likely occurs because the FFmpeg development libraries (containing libavformat, libavcodec, etc.) are not installed or not properly configured in the system. These libraries are typically required for video-related functionality, and pkg-config cannot locate them to generate compiler flags.
Application Crash on Windows 11 When Clicking Taskbar Icon
How to reproduce
1、Run the gpu/examples/phong on Windows 11. 2、Click or double-click the application icon in the Windows taskbar (bottom of the screen) while the program is running.
